Finca 6 Sphere Museum near Palmar Sur is Costa Rica's only UNESCO World Heritage archaeological site where ancient Diquís stone spheres — crafted over a thousand years ago — remain in their original linear arrangements amid a lush former banana plantation.
Costa Rica: Puntarenas Province – Corcovado National Park
🌿 Corcovado National Park: A Proper Gem on the Osa Peninsula
Now, if you’re anything like us, you might look at a map of Costa Rica and think, “Right, nice little country, let’s crack on.” But then you get to the Osa Peninsula in the far south-west, and your jaw just drops. Sitting on that peninsula, covering roughly a third of its entire landmass, is Corcovado National Park — and blimey, what a park it is.
Established in 1975, Corcovado stretches across 41,788 hectares — around 103,260 acres for those of us who still think in old money — protecting an extraordinary patchwork of shallow coastal lagoons, boggy marshland, mangrove swamps, winding rivers, wet lowland forest, low-altitude cloud forest, and 46 kilometres of sandy beach. Not bad for a day out.
Corcovado isn’t just big — it’s alive in a way few places can claim. Scientists have long regarded it as one of the most biologically intense ecosystems in all of Central America, and the numbers back that up. Within its boundaries, we found around 6,000 insect species, 500 tree species, 367 bird species, 140 mammal species, 117 amphibians and reptiles, and 40 freshwater fish species. Jaguars still prowl here too, which is not something you can say about many places left in the world.
Unlike most of Costa Rica’s parks, Corcovado has six separate entrance points — and because the roads of the Osa Peninsula were clearly designed by someone with a very mischievous sense of humour, these entrances can be several hours apart by car even when they look close on a map.
The six entry points are: San Pedrillo, Sirena, La Leona, El Tigre, Los Planes, and Los Patos. The four busiest ranger stations are Sirena, San Pedrillo, La Leona, and Los Patos. Sirena, sitting deep in the park’s heart, is the one most serious wildlife watchers aim for — reachable by coastal hike, boat, or small charter flight from Drake Bay.
Plan this bit carefully before setting off. Each entrance serves a different section of the park, and the trails between them are not the sort of thing you tackle on a whim.
🧭 How Do We Actually Visit Corcovado?
Right, so you’ve decided Corcovado is on the list — good shout. But how you visit depends on three things: how much time you’ve got, how fit you’re feeling, and whether roughing it in a rainforest sounds like a laugh or an absolute nightmare. Tours broadly come in three flavours: one-day, two-day/one-night, or three-day/two-nights.
One thing that’s non-negotiable regardless of which option you choose — you must enter the park with a registered guide. No exceptions, no winging it.
🚤 The One-Day Option
For those short on time, the classic one-day tour involves a boat ride from either Puerto Jiménez or Drake Bay straight to Sirena Station, a good stomp around the trails, and then a boat back. Quick, efficient, and you still get a proper taste of the place. We stayed at one of the resorts in Carate and did our day trip from there, which worked a treat and we’d thoroughly recommend it.
🌙 The Two-Day/One-Night Option
Step it up a notch and the two-day tour usually kicks off from Drake Bay or Puerto Jiménez — either a boat across to Sirena Station or a drive to Carate followed by a hike in. You overnight at Sirena, head out on forest trails the following morning, then make your way back. A much more immersive experience and well worth the extra night.
🎒 The Three-Day/Two-Night Option
This is the full works. Tours typically begin and end in Puerto Jiménez, from where you drive to either Carate or the Los Patos entrance, hike through to Sirena Station, and exit from whichever end you didn’t start at before returning to Puerto Jiménez. Proper jungle adventure stuff.
💰 What’s It Going to Cost?
As you’d expect, prices vary considerably depending on what you opt for. A day trip can come in at under $100, while a multi-day expedition will set you back $400 or more. Have a look at Osa Wild and Sukia Travel for current options and pricing.
🏕️ The Ranger Stations
Carate sits 26 miles (43 km) south-west of Puerto Jiménez along what can only be described as a road that someone clearly gave up on halfway through — rocky, muddy, riddled with potholes, and genuinely challenging during the wet season. That said, it’s the gateway to the La Leona Ranger Station, which offers potable water, showers and campsites. From La Leona, it’s a further 9 miles west along the coastline to reach Sirena.
Sirena Ranger Station sits a few hundred yards back from the coast, with a grass landing strip between the station and the sea — used by the small charter planes that serve the park. Seven hiking trails radiate out from here, winding through magnificent primary rainforest between the Río Claro to the south and the Río Sirena to the north.
There’s no camping at Sirena, so bunkhouse reservations are essential. No outside food is permitted either — all meals must be bought at the cafeteria ($20 breakfast, $25 lunch, $25 dinner). The station itself is a collection of wooden buildings connected by covered walkways, which, given that rain here is less of an occasional inconvenience and more of a way of life, turns out to be a rather sensible bit of design.
🥾 Hiking On from Sirena
From Sirena, we had a couple of decent options. The first was to hike back the way we came towards Carate. The second — for those with energy to spare and sturdy knees — was to push on a further 14 miles along the coast to San Pedrillo Ranger Station, and then a further 11 miles on to Drake Bay. We’ve written a full post on Drake Bay if you want the detail on that.
The alternative to the coastal slog to San Pedrillo is to head inland instead, pushing deep into the rainforest, past the beautiful Laguna Corcovado and climbing up towards the cloud forest to Los Patos Ranger Station — around 10 miles (16 km). From Los Patos, it’s straightforward enough to arrange a lift through to Puerto Jiménez.
If hiking isn’t your thing — or your boots have given up the ghost — a popular way to arrive at and depart from Sirena is simply by boat from either Drake Bay or Carate. Much more civilised, frankly.
The trails through Corcovado are well-established and, for the most part, in reasonable condition. But let’s be honest about what we were dealing with here — this is a rainforest, and it gets properly wet. Especially during the green season, when the heavens open with an enthusiasm that would make even a Londoner wince.
Even in the dry season, we hit muddy patches regularly. Tree roots lurk everywhere and become genuinely treacherous underfoot regardless of the time of year — so eyes down and watch your step.
River crossings are part of the deal on several trails. In the dry season these might be no more than ankle-deep trickles — pleasant enough. In the green season, those same crossings can be thigh or even waist-deep, with a current moving fast enough to make you think twice. Worth bearing in mind before we set off.
🏖️ The Beaches
The Osa Peninsula has some genuinely wonderful beaches, and the really rather brilliant thing is that you’ll almost certainly have them entirely to yourself. No sunbeds, no beach bars blasting out music, no one trying to sell you a knock-off watch. Just you, the sand, and the jungle pressing right up to the waterline. Bliss.
That said, let’s not get carried away with the romance of it all. Beach hiking in Corcovado is exposed, relentless, and hot in a way that those of us from grey, drizzly London are simply not built for. We’re talking proper tropical sun here — the kind that doesn’t mess about. If you don’t treat it with serious respect, it will put you in hospital before you’ve even had a chance to admire the view. Hat, high-factor sunscreen, plenty of water, and an early start are not optional extras — they are absolutely non-negotiable.
🌊 Watch Yourself in the Water
Riptides are common along these beaches, so always check with the Rangers or local people before swimming in any waters you don’t know. This is genuinely important advice, not the sort of thing to skim past.
If you do get caught in a rip and find yourself being dragged out to sea — and it can happen faster than you’d think — the instinct is to panic and swim straight back to shore. Don’t. Swim parallel to the beach instead, until you feel the current release you, then make your way in calmly. Fighting a riptide head-on is a battle you won’t win.
🐾 The Wildlife
Right then, let’s talk about the animals — because this is really why most of us make the trek to Corcovado in the first place. The park is home to a quite staggering 124 mammal species. We’re talking bats, pumas, jaguars, Baird’s tapirs, anteaters, white-lipped peccaries, and all four of Costa Rica’s monkey species — spider, white-faced, howler, and squirrel. It’s basically a greatest hits collection of tropical wildlife.
🐗 White-Lipped Peccaries — Give These Lads a Very Wide Berth
Now, the white-lipped peccary deserves a special mention. These hog-like creatures have been largely wiped out across much of Costa Rica, but in Corcovado they are positively thriving. They travel in groups of up to 300 individuals and when they decide to move through the rainforest, they don’t quietly tiptoe — they stampede.
Here’s the thing though: they are not to be trifled with. Their sharp teeth are normally used to tear through rocky soil and roots while foraging, but make no mistake, those same teeth will cut through flesh and bone with very little encouragement. Their eyesight is poor, which makes them jumpy, and a startled peccary — or one that thinks you’re squaring up to it — can turn aggressive with alarming speed. They’re not actively hunting you down, but they won’t lose much sleep over giving you a nasty time if they feel cornered.
If we find ourselves in the path of a herd, the advice is simple: back off immediately, and if backing off isn’t an option, find a tree and climb it. Sit tight and wait for them to move on. Not the most dignified exit, but infinitely preferable to the alternative.
🐆 Five of Central America’s Six Wild Cats
Corcovado is one of the very few places in Central America where you have a genuine chance — however slim — of encountering five of the region’s six wild cat species. Jaguars, pumas, ocelots, margays, and jaguarundis all call this park home. Spotting a jaguar in the wild is genuinely rare, and most visitors never manage it, but knowing they’re out there padding silently through the undergrowth gives the whole experience a rather wonderful edge. They are, without question, the undisputed kings of Corcovado.
🦥 The Rest of the Gang
The mammal roll call doesn’t stop there, not by a long stretch. We also came across tamanduas — a mid-sized anteater equipped with an extraordinary 16-inch tongue built for raiding termite mounds — and coatis, those endlessly busy raccoon-like creatures that’ll scavenge absolutely anything going, from crabs to bird eggs. And dangling from the branches above it all, in that wonderfully unbothered way of theirs, were both two-toed and three-toed sloths. Brilliant animals. Absolutely no interest in the world’s opinion.
If you’re even remotely interested in birds — and after a visit here, you will be — then Corcovado is going to make your head spin. The park supports a genuinely healthy population of scarlet macaws, and spotting one of these impossibly vivid creatures flying overhead is the sort of moment that stops you dead in your tracks.
But the macaws are really just the opening act. We also came across crimson-fronted parakeets, red-lored Amazon parrots, Baird’s trogons, and the brilliantly named fiery-billed aracari, which sounds made up but very much isn’t. Add to that 10 woodpecker species hammering away at the forest, 15 tanager species doing their colourful best, and no fewer than 20 hummingbird species hovering about the place like tiny jewelled helicopters, and you start to get a sense of just how extraordinary the birdlife here really is.
And then there’s the harpy eagle. The largest and most powerful raptor in the entire Americas, this is a bird that looks like it was designed specifically to intimidate everything else in the forest — and it does a thoroughly convincing job of it. Sightings are rare, but they do happen in Corcovado, and if we’re honest, just knowing they’re out there somewhere adds a certain frisson to a morning walk through the trees.
The park is also home to several bird species found nowhere else, including the yellow-billed cotinga and the black-cheeked ant-tanager — both endemic to this small corner of Costa Rica and both very good reasons to keep the binoculars handy at all times.
There are plenty of reptiles to find in Corcovado, and the snake situation alone is enough to keep you on your toes. The park is home to a good number of species — both venomous and the constricting variety — going quietly about their business in the undergrowth, up in the canopy, and along the riverbanks.
Honestly, the chances of actually spotting one are fairly slim unless you’re actively looking, moving slowly, and know what you’re searching for. Most snakes here are masters of camouflage and would far rather slip away unnoticed than have any sort of encounter with a pair of walking boots. That said, Corcovado does host some genuinely serious species — the Fer-de-Lance, for instance, is not a snake you want to stumble across unexpectedly, and the Bushmaster, the longest venomous snake in the Americas, also calls this forest home.
So whilst we wouldn’t want to put anyone off, the golden rule is a simple one: don’t reach into anywhere you can’t see first. That means rocky crevices, hollow logs, thick leaf litter, and the base of dense vegetation. Have a good look before you put your hand anywhere. It’s just common sense, really — the same rule that applies to putting your hand behind the sofa at home, except here the stakes are considerably higher.

🗺️ Getting There
Corcovado sits on the remote Osa Peninsula in southwest Costa Rica. Most visitors fly into San José (Juan Santamaría International Airport) and then take a domestic flight or bus south. The quickest route is a short charter flight to Drake Bay or Carate, from where the park entrances are reachable on foot or by boat. By road, the drive from San José to Puerto Jiménez — the main gateway town — takes around 8 hours via the Costanera Sur highway, much of it unpaved once you leave the main road. A 4WD vehicle is strongly recommended. From Puerto Jiménez, boats, taxis, and organised tours can take you to the park’s various entry points. Note that Sirena station, the most popular base inside the park, is only accessible by boat or a multi-hour jungle hike — there is no road access.
Best Time to Visit Costa Rica’s West Coast
🌞 Dry Season (December to April)
This is the classic high season and, for most visitors, the most straightforward time to travel. Skies over Guanacaste and the Nicoya Peninsula are reliably clear, rainfall is minimal, and the Pacific Ocean tends to be calm and brilliantly blue. Temperatures sit between 28°C and 35°C, and the trade winds that blow in from the north keep the heat from becoming oppressive — particularly along the coast. Playa Tamarindo, Playa Flamingo, Playa Conchal, and Playa Nosara are all at their most photogenic during these months. The dry season also coincides with prime surfing conditions at breaks such as Witch’s Rock and Ollie’s Point, which are accessible by boat from Tamarindo and Playa del Coco. Wildlife is highly visible because animals congregate around remaining water sources. Leatherback sea turtle nesting at Playa Grande peaks between November and February, and January through March sees excellent whale-watching offshore. The trade-off is that this period is busy and expensive. Accommodation should be booked months in advance, especially over Christmas, New Year, and Semana Santa (Easter Week), when prices spike considerably and beaches become crowded.
What to pack: Lightweight, breathable clothing (linen or technical fabrics), high-SPF sun cream, a good sun hat, UV-protective sunglasses, sandals and sturdy walking shoes, a reusable water bottle, insect repellent, a light layer for air-conditioned restaurants and transfers, swimwear, a dry bag for beach days and boat trips, and any prescription medication.
🌦️ Shoulder Season / Green Season Onset (May to June)
May and June mark the start of the rainy season, but the transition is gradual and, for independent travellers, arguably the most rewarding period of the year. Rain tends to fall in concentrated afternoon or evening downpours rather than all-day grey drizzle, leaving mornings consistently bright and warm. The landscape transforms almost overnight: the brown, parched hillsides of the dry season give way to a lush, vivid green that earns this period its alternative name, the Green Season. Crowds thin out noticeably, prices drop across hotels and tour operators, and the roads are quieter. Surf conditions remain strong along the northern Nicoya coast. The warm, rain-fed rivers begin to run well, making inland excursions and wildlife spotting increasingly rewarding. May and June represent excellent value without any significant sacrifice in terms of day-to-day enjoyment.
What to pack: A quality lightweight waterproof jacket or packable poncho, quick-dry clothing, waterproof sandals or trail shoes, a dry bag, insect repellent (mosquito activity increases with the rains), sun cream, swimwear, a small travel umbrella, a portable power bank to keep devices charged during downpours, and a microfibre towel.
🌧️ Mid Rainy Season (July to August)
July and August bring an interesting anomaly known locally as the veranillo, or “little summer” — a brief dry spell that typically occurs in late July and can extend into August. For travellers who plan around this window, the experience can feel much like the dry season: clear blue skies, calm seas, and excellent beach conditions. Outside the veranillo, rainfall is heavier than in May and June, with proper thunderstorms rolling in during afternoons and evenings. Rivers run fast, waterfalls are at their most spectacular, and the rainforest canopy is at peak density. This is also one of the best periods for sport fishing offshore, and humpback whale season is in full swing from July onwards, with pods regularly spotted along the Guanacaste coast and around the Nicoya Gulf. Prices remain low, and popular spots are uncrowded. Road conditions on unpaved tracks can become challenging, and some more remote beaches may be harder to reach. That said, a 4×4 vehicle and a flexible itinerary turn what might seem like obstacles into genuine adventure.
What to pack: A robust waterproof jacket, quick-dry shirts and trousers, waterproof hiking boots or heavy-duty sandals, a dry bag for electronics and documents, insect repellent with DEET, malaria prophylaxis if venturing into forested inland areas (consult your GP), a first-aid kit, sun cream (for the veranillo and coastal days), swimwear, a headtorch, and cash (ATMs can be unreliable in remote areas).
⛈️ Peak Rainy Season (September to November)
September and October are the wettest months on the West Coast. Rainfall totals are at their highest, and there can be multi-day spells of overcast, damp weather — particularly in October, which is statistically the wettest month in Guanacaste. Tropical storms, while not guaranteed, are possible during this period and the broader Atlantic hurricane season can occasionally push systems across from the Caribbean side. That said, the West Coast of Costa Rica is far less vulnerable to hurricanes than the Caribbean coast, and many visitors find this time perfectly manageable with the right expectations. Prices are at their absolute lowest, and top-end eco-lodges that are often fully booked in December can be available at a fraction of the usual rate. The natural environment is extraordinarily alive: nesting olive ridley sea turtles arrive in mass nesting events called arribadas at Playa Ostional on the Nicoya Peninsula, and the rivers and forests teem with wildlife. November brings a gradual improvement as the rains begin to ease and the first dry-season visitors start to arrive, making it a transitional month with a pleasant mix of green landscapes and increasing sunshine.
What to pack: Full waterproofs (jacket and trousers), waterproof footwear, a dry bag, anti-malarial tablets if applicable (seek medical advice), DEET insect repellent, lightweight long-sleeved shirts and trousers for evenings and forest hikes, a portable water filter or purification tablets, a headtorch, a backup power bank, a travel insurance policy that covers weather-related disruptions, and sun cream for clear spells.
🌍 Overall Best Time to Visit
For most travellers, January to April offers the most dependable weather and the widest range of activities on Costa Rica’s West Coast, with February and March sitting at the sweet spot of excellent conditions before the Easter crowds arrive. However, those willing to embrace a little unpredictability will find remarkable rewards in the shoulder months. May to June and the veranillo of late July deliver much of the same beauty at considerably lower cost, with the added bonus of lush green scenery and far fewer fellow tourists. The true adventurer, seeking an untouched, immersive Costa Rica, might even consider October — the country at its most wild, wet, and wonderfully alive.
Where to stay around Corcovado National Park
Puerto Jiménez is a small town but it is an ideal gateway for tours into the Corcovado. Cabinas Jiménez is a great option as a base for your exploration of the National Park. The staff are super friendly and it is also a safe place to leave your rental car if you are doing a multi-day tour.
We decided to spend a few days in Carate, about 23 miles southwest of Puerto Jiménez along very bumpy roads. You might want to think about leaving your rental car in Puerto Jiménez if it is not a 4×4 and catch a taxi. We loved our time at Finca Exotica Eco Lodge. There are other highly rated lodges in the area including Luna Lodge and La Leona Eco Lodge. From Carate you can get a local guide to take you to the Corcovado National Park on foot and reach La Leona and La Sirena Ranger stations.
Another great option is to stay on the opposite side of the peninsula from Puerto Jiménez in the small community of Drake Bay, which is best reached by boat from Sierpe. You can hike from Drake Bay to the San Pedrillo Ranger station or take a boat to Sirena Ranger station for a day or multi-day trip. We stayed at the rustic and affordable Bella Vista Corcovado. Other good options include Copa De Arbol Beach & Rainforest Resort and Cabaña Ara Macao Lodge
