Tortuguero National Park is a remote Caribbean rainforest haven in Costa Rica renowned for its labyrinthine waterway network nesting sea turtles and extraordinary biodiversity making it one of the most captivating eco-tourism destinations in all of Central America.
Costa Rica: Limon Province – Moin to Tortuguero National Park
🌧️ Even Paradise Has Its Off Days
Even paradise can look utterly miserable on a wet day, and that is precisely where we found ourselves on the morning of day five in Costa Rica. The sky had decided to open up with considerable enthusiasm and showed absolutely no signs of stopping. Fortunately, today was a travel day — we were heading to Tortuguero National Park — so we could afford to be philosophical about it. We managed that with only mild complaining, which for us was practically cheerful.
🐢 The Man Who Put Tortuguero on the Map
The story of Tortuguero — whose name translates rather poetically as “Place of the Turtles” — began in earnest in 1953, when an American marine biologist named Archie Carr made the long and uncomfortable journey to this remote stretch of Costa Rica’s Caribbean coast. Carr was a distinguished zoologist from the University of Florida, and he had been hearing persistent reports of enormous green sea turtle nesting grounds somewhere along this wild and largely inaccessible coastline. He came to have a look. What he found stopped him in his tracks.
The dark volcanic sand beaches of Tortuguero, he quickly realised, were not just significant. They were the single most important green sea turtle nesting ground in the entire Western Hemisphere. Every year, between June and October, tens of thousands of green sea turtles hauled themselves out of the Caribbean and lumbered up those beaches to lay their eggs — a spectacle that had been going on, essentially unchanged, since the age of the dinosaurs. Carr spent years documenting this extraordinary phenomenon and lobbying the Costa Rican government to protect it. His persistence eventually paid off. In 1975, more than 35 kilometres (22 miles) of beach and the surrounding jungle were officially designated as Tortuguero National Park.
The timing was fortunate. Across the rest of the world, green sea turtle populations have fallen sharply since then, battered by habitat loss, fishing nets, and the persistent human habit of eating things we really shouldn’t. Yet at Tortuguero, the opposite has happened. Nesting numbers have risen by nearly 500% since the park was established. Today, roughly 20,000 green turtles nest here each year, making it the largest colony of nesting green turtles on the planet. Archie Carr would have been delighted. We were here outside of turtle nesting season, which was a shame, but as it turned out, there was rather a lot else to be getting on with.
🌿 A Wilderness Worth Getting Wet For
Just behind the beach, a network of serpentine rivers winds deep into the jungle, opening up a lush and staggering wilderness. Tortuguero is home to 60 mammal species, 57 amphibian species, 111 reptile species, over 300 bird species, more than 400 tree species, and upwards of 2,000 plant species. In short, the place is absolutely heaving with life, which is either thrilling or alarming depending on your feelings about crocodiles.
We explored the waterways by motor boat, drifting quietly past the overhanging trees while monkeys crashed about overhead, sloths hung with magnificent indifference from the branches, and the occasional caiman slid into the water with a composure that frankly put the rest of us to shame. It is easy to see why Tortuguero has become the top eco-destination on Costa Rica’s Caribbean coast and the country’s third-most visited national park. It really is spectacular — even in the rain. Especially in the rain, perhaps, if you are the sort of person who enjoys being soggy in a beautiful place.
🚢 Getting There: The Moin Option
We were travelling up from Puerto Viejo de Talamanca, in the southern reaches of the Caribbean coast, which meant our best route was via the docks at Moin — a journey of roughly three to four hours by boat through the canals and waterways. There is one public boat a day from Moin, which departs at around 10:00 am. Modula advice suggests arriving at least 30 minutes early, and given that missing the only boat of the day would have made for a deeply unpleasant afternoon, we took this seriously. We had an early breakfast and were on the road by 8:00 am for the hour-long drive from Puerto Viejo. We had a hire car, though for those without one, shuttle buses and tour operators run the route from Puerto Viejo to Moin for a perfectly reasonable fee.
The rain was still hammering down when we reached the small dock area at Moin, which sits right alongside the working container port — an atmospheric combination, as you can imagine. There were a handful of boats, which pretty much accounted for the entire harbour. There was something loosely described as a car park, which claimed to be secure. I was not entirely convinced by this claim. Fortunately, it was a hire car and we were fully insured, so we locked up, left absolutely nothing of value inside, and tried to look unconcerned. We were not charged for parking, but were told to tip “the man” on our return from Tortuguero. Exactly which man remained something of a mystery, and we filed this under Things To Worry About Later.
We had booked our places on the boat through a local travel company, though “booked” is perhaps putting it rather grandly. There was no confirmation number, no ticket, no email — nothing you could wave at anyone in a moment of dispute. The instructions had been simple enough: find Captain David, hand over 35 US dollars per person, and he would sort us out. This is the sort of arrangement that makes me quietly anxious. I am, I freely admit, a hopeless worrywart when it comes to travel, the sort of person who triple-checks departure times and arrives at airports roughly three hours before strictly necessary. But this is Costa Rica, and informality is simply how things work here. You either embrace it or spend the whole holiday with a slightly hunted expression. We embraced it. Mostly.
We made our way across the dock towards a group of men sheltering under a corrugated roof, exchanged a few pleasantries, and asked whether a Captain David happened to be among them. One of the men raised a hand, took our money without much ceremony, and told us to hang around. And that, apparently, was that. Berths secured. Probably.
We retreated to a ramshackle single-storey building nearby that served as the terminal, if one is using the word very loosely indeed, and made use of the facilities — this being strongly advisable, as there are no toilets on the boat and precisely one stop along the entire three-and-a-half-hour journey. We then stood in the rain and waited, which is something the British are extraordinarily well-practised at.
After a while, things began to happen. A man arrived in a battered pickup truck, jumped out, and hauled two large barrels of petrol onto the dock. He then produced a length of rubber tubing, inserted one end into the barrel, placed the other end firmly in his mouth, gave it an enormous and committed suck, yanked the tube free from his lips at precisely the right moment, and redirected it into what we assumed was the fuel tank of the boat. Siphoning by mouth. Bold. We watched this with a mixture of admiration and mild alarm, and said nothing.
With the boat fuelled — by whatever margin of safety that represented — it was time to load the bags. This was when we got our first proper look at our vessel. It was tiny. Accommodation for perhaps twenty people at a squeeze, with a roof of sorts but otherwise entirely open to the elements on all sides. About half a dozen fellow travellers were already waiting with us, every single one of them thoroughly drenched. Our crew, to their credit, had a solution for the luggage: a collection of black bin bags, each one sporting a generously sized hole, into which we deposited our belongings before they were stowed somewhere in the uncovered rear of the boat. Waterproofing, Costa Rica style. And with that, we climbed aboard and set off.
We set off at a pleasantly unhurried pace, which suited us rather well. After a few hundred yards the captain cut the engine and we drifted gently towards the riverbank. My immediate thought was that something had broken down, which would have been entirely on brand for the day so far. It hadn’t. On the outbound journey to Tortuguero, the crew make a point of turning what is essentially a transfer into something resembling an actual tour, which was a rather nice touch. The captain gestured towards a tree hanging low over the water, and there, looking extraordinarily sorry for itself, was a three-toed sloth. Absolutely sodden. Whether it was actually miserable or perfectly content dangling in the downpour is, of course, anybody’s guess — I may have been projecting. We then motored across to the opposite bank, where another sloth was doing much the same thing.
From our sloth spotting, we chugged on up the river for another half a mile or so before the captain decided he’d been patient long enough, opened the throttle, and suddenly we were skipping across the water at a decent lick. It was actually quite thrilling, hurtling around the long sweeping bends with the jungle blurring past on either side. The boat’s canvas roof, bless it, turned out to be largely decorative — more of a suggestion of shelter than anything approaching actual protection — and within minutes we were absolutely soaked. Drenched. Comprehensively wet in ways that require a change of clothes and a quiet moment of reflection. Still, at least it was warm rain. Small mercies, as my mother used to say.
The route from Moin to Tortuguero threads its way through a mix of natural river channels and man-made canals — a watery highway that the locals have been using for generations, largely because there is no road and nobody seems particularly bothered about building one. At various points along the way, the river opens out towards the Caribbean coast and you catch glimpses of waves breaking on the dark sand beaches. It was rather dramatic, in a grey and windswept sort of way.
The waterways are not entirely straightforward. Fallen debris is a constant presence, and while most of it is the sort of thing you can nudge past without incident, we rounded a bend on one of the narrower canals to find an enormous tree sprawled halfway across the water. Apparently, the trees along these banks have extraordinarily shallow root systems, which means they topple into the canal with impressive regularity. Our captain, who had clearly seen this sort of thing before and was entirely unbothered by it, manoeuvred around the obstruction with the quiet confidence of a man parallel parking a very familiar car, and we were back up to full speed within minutes.
The wildlife kept us entertained throughout. The riverbanks were busy with spoonbills, pelicans, herons, and cormorants going about their business with great purpose. Then, just as we crossed into the boundaries of Tortuguero National Park, a very large crocodile announced itself from a sandbank, looking ancient, immovable, and entirely unimpressed by our arrival.
After about three hours on the water, we pulled into Tortuguero — wet, bedraggled, and looking like something the tide had brought in. The dock was tiny, as was the village itself, a modest little settlement sitting on a narrow rainforest-covered sandbar, completely hemmed in by the national park on all sides. There is no road in or out — the only way to arrive is by boat or small plane, which does give the place a rather pleasingly end-of-the-world feel. We unloaded quickly. The rain had briefly and mercifully stopped, so we grabbed our bags and scuttled off to find the hotel before it changed its mind.

Best Time to Visit Costa Rica
🌞 Dry Season (December to April) — High Season
Costa Rica’s dry season runs from December to April and is widely regarded as the most popular time to visit. The weather across most of the country is reliably warm and sunny, with low humidity and minimal rainfall making it ideal for outdoor activities, beach holidays, and exploring national parks. The Pacific Coast — including destinations such as Manuel Antonio, Tamarindo, and the Nicoya Peninsula — is at its most accessible and attractive during these months, with calm seas ideal for surfing, snorkelling, and boat trips. The Central Valley and highlands enjoy clear skies, making the volcano landscapes and cloud forests particularly stunning. December and January bring a festive atmosphere, whilst February and March are often considered the absolute peak of the season. April marks the tail end of the dry season, still largely pleasant but with the first hints of rain beginning to return.
Wildlife watching is excellent throughout this period, with animals more visible around water sources as vegetation thins. Humpback whales can be spotted off the Pacific coast, and sea turtle nesting begins to pick up towards March and April.
The trade-off for all this good weather is crowds and cost. Hotels, tours, and flights tend to be at their most expensive, and popular attractions can feel busy. Booking well in advance — ideally three to six months ahead — is strongly recommended.
What to pack: Lightweight, breathable clothing in natural fabrics, a high-factor sun cream (SPF 50+), a wide-brimmed hat, UV-protective sunglasses, sturdy walking sandals and light trainers, a reusable water bottle, a compact day rucksack, insect repellent, a light layer or thin fleece for highland evenings, and a small dry bag for beach excursions.
🌧️ Green Season / Rainy Season (May to November) — Low Season
The green season, as it is affectionately known locally, spans May to November and coincides with Costa Rica’s rainy season. Whilst this deters many visitors, it rewards those who travel during this period with lush, vivid landscapes, fewer tourists, significantly lower prices, and a more authentic experience of the country. Rainfall typically arrives in short, sharp afternoon downpours rather than all-day drizzle, leaving mornings largely clear and perfectly workable for sightseeing and activities.
The Caribbean Coast — including Puerto Viejo and Tortuguero — operates on a different weather calendar and is often drier during the months of September and October when the Pacific side is at its wettest. This makes the Caribbean an excellent option during those months. The rainforest is at its most spectacular during the green season; waterfalls are full and thundering, rivers run high, and the wildlife is extraordinarily active. The months of July and August offer a brief dry spell known as the veranillo or little summer, during which Pacific-coast conditions temporarily improve.
This is an excellent period for white-water rafting, as rivers are swollen and fast-moving. Turtle nesting on both coasts reaches its peak — particularly at Tortuguero, where green turtles nest in enormous numbers between July and October. Surfers will find some of the best swells of the year along the Pacific coast during this season.
What to pack: A quality waterproof jacket or rain poncho, quick-dry clothing, waterproof hiking boots with good grip, waterproof covers for bags and rucksacks, a dry bag or waterproof pouches for electronics, extra pairs of socks, insect repellent, anti-fungal foot powder, a travel umbrella, and a light fleece for cooler highland evenings. A dry bag for camera equipment is especially advisable.
🌤️ Shoulder Seasons (Late April / Early May and November)
The shoulder periods — roughly late April into May, and the month of November — represent an increasingly popular sweet spot for experienced travellers. The weather in late April and early May retains much of the dry season’s charm whilst prices begin to ease and crowds thin noticeably. November is similarly transitional: the rains are winding down across the Pacific side, landscapes remain beautifully green, and accommodation and tour costs drop sharply after the October lows.
These months offer a genuine best-of-both-worlds experience for those with flexibility. Wildlife activity is high, national parks feel less overrun, and there is often a greater sense of ease in navigating the country — from roads to restaurants.
What to pack: A versatile layering system suitable for both sun and rain, a lightweight waterproof jacket, a combination of quick-dry and breathable clothing, good-quality walking shoes, sun cream, insect repellent, a hat that doubles as sun and rain protection, and a mid-size rucksack suitable for day trips and overnight excursions.
🗻 Visiting the Highlands and Volcanoes
The Central Highlands — home to Monteverde, Arenal, and the Poás and Irazú volcanoes — follow a slightly different pattern from the coasts. Cloud forests such as Monteverde are at their most atmospheric and enveloped in mist during the wetter months, creating an ethereal, primordial quality. However, they can be quite cold and damp, particularly at altitude. Arenal Volcano is most visible during the dry season, as cloud cover frequently obscures its summit during the rainy months. Those travelling to highland areas at any time of year should be prepared for cooler temperatures, often 10–18°C at altitude, and the possibility of sudden mist and light rain regardless of season.
What to pack for highlands: Warm layers including a fleece or lightweight down jacket, waterproof outer layer, long trousers, sturdy waterproof hiking boots, warm socks, a hat and light gloves for evenings, and a headtorch for early morning wildlife walks.
🐢 Wildlife and Natural Events by Season
Costa Rica’s remarkable biodiversity means there is always something extraordinary happening in nature, regardless of when you visit.
December to April: Dry forests thin out, making wildlife easier to spot. Humpback whales are present off the Pacific coast (particularly January to March). Mating season for many bird species begins. The scarlet macaw is highly visible in the Osa Peninsula.
May to July: Olive Ridley and Leatherback turtles begin nesting on the Pacific coast. Cloud forests are vibrant with amphibians and insects. Birdwatching is exceptional as migratory species pass through.
July to October: Leatherback, Green, and Hawksbill turtles nest on the Caribbean coast, with Tortuguero offering extraordinary night-time nesting experiences. Humpback whales return to the Pacific (July to November). Baby sea turtles hatch in August and September.
October to December: Whale sharks can be spotted around Cocos Island. The Caribbean coast dries out, making it one of the best times to visit the east. Migratory birds begin arriving from North America.
📋 Season-at-a-Glance Summary Table
🌍 Overall Best Time to Visit Costa Rica
For most travellers visiting Costa Rica for the first time, the period from mid-December to March represents the optimal window. The weather is at its most consistently dry and sunny, the full range of activities and national parks are accessible, and the country is buzzing with energy. Those who prioritise value for money, solitude, and a more immersive experience of the rainforest are very well served by visiting between June and August, when the veranillo provides a brief respite from the rains and prices are meaningfully lower. For the discerning traveller who wants the best balance of good weather, reasonable cost, and thinner crowds, November stands out as a particularly well-kept secret — the rains are easing, the landscapes remain lush, and the country feels unhurried. Costa Rica rewards visitors in every season; the question is simply one of priorities.
