Not many people know this, but although the whole area is known as Halong Bay, there are in fact 3 different bays: Halong Bay, Bai Tu Long Bay and Lan Ha Bay. All three bays have virtually indistinguishable karst landscapes.
One of the things we were most looking forward to during our visit to Vietnam was a 3 day/2 night cruise in Bai Tu Long Bay – a neighbour of the more famous Ha Long Bay.
About Ha Long Bay
Ha Long Bay, Vietnamese Vinh Ha Long (“Where the Dragon Descends to the Sea”), bay on the northwest coast of the Gulf of Tonkin, near the city of Ha Long (Hong Gai), Quang Ninh province, northern Vietnam. Situated 102 miles (164 km) southeast of Hanoi, the 580-square-mile (1,500-square-km) area contains some 3,000 rocky and earthen islands, typically in the form of jagged limestone pillars jutting out from the sea, and several caves and grottoes, all of which blended to produce an exotic and picturesque seascape. A diverse population of marine and land mammals, reptiles, fish, and birds are found in the waters and tropical forests. It is listed on the register of UNESCO World Heritage sites.
There are two similar legends about the origin of the bay, which are reflected in its name. The first legend asserts that a dragon stomped on the earth with such force that mountains crumbled, forming large valleys that soon filled with water; only the peaks of mountains—now the rocky islands of Ha Long Bay—remained above the surface. The alternate folklore tells of a dragon whose large tail tore up the earth, creating valleys and crevices that became flooded when the beast jumped into the nearby water. Both versions lent themselves to the modern-day legend of Tarasque, a dragon-like marine creature believed to inhabit the bay.
Bai Tu Long Bay
Our boat tour would take us to Bai Tu Long Bay, located east of Ha Long Bay and far from all the tourist sites. Bai Tu Long Bay is a lesser-known alternative to Halong.
The limestone karst landscape at Bai Tu Long Bay is virtually indistinguishable from Ha Long and Bai Tu Long Bays. The benefit of coming here is that it is probably the least developed of the three bays and sees the least number of tourists.
Our Tour
We were collected from our hotel and transported, along with our fellow passengers towards Ha Long Bay. Our guide for the day was Man (pronounced ‘mon’). Along the way, we stopped at a shop that sells pearl jewellery made from pearls harvested in the area.
Leaving the pearl shop, we grabbed a smoothie and jumped back onto the bus for the remaining 20-minute drive to the harbour at Ha Long. We were not due to board for another hour or so which meant hanging around in a waiting area, which soon passed and in no time, we were heading out on a tender to our Swan Cruise ship. It was a relatively small boat with 18 cabins on three decks and one dining area. We had a room right on the stern of the boat on the second deck, which meant we were one of four cabins with a balcony. The room was spacious with a huge bathroom, at least for a boat with a jacuzzi bath.
After checking out our room it was time to head to the dining room for lunch which was served as we cruised out into the bay.

Our tour took us to Bai Tu Long Bay, north of Ha Long Bay, where there are virtually no day cruises, so it is much quieter and has very similar islands.
In the afternoon we climbed aboard the small tender and headed out to a small dock area. Here we clambered into two-person sit-on kayaks and followed Man in his kayak around the islands. It was stunning, even though the visibility was not great due to the misty conditions. After about 20 minutes we pulled up on a small beach. Karen was still feeling a bit delicate from the sickness she picked up in Hanoi, so she didn’t fancy swimming, but I decided to brave the waters. It was not too cold.
We stayed on the beach for a bit before paddling back to the jetty. From there it was back on the tender to the Swan Cruise boat.
By now it was late afternoon, so after a quick shower we headed up to the open top deck for an afternoon drink to watch the sun go down. The misty conditions did not make for the greatest sunset experience.
One of the after-dinner options was to try and catch squid on a line from over the side of the boat. We didn’t manage to catch any.
Day Two
The day’s first order was a short Tai Chi class on the upper deck led by Man. There was quite a good turnout considering it was early morning and the weather was a little grey and damp. We worked through five different sequences before pulling them all together for a final run-through. The only disconcerting thing was when the boat started to cruise as we were doing the moves.
The routine for the day was for the Swan Cruise ship to return to Ha Long to drop off those who were only staying one night and return with some new passengers. Those of us staying for the two nights would be transferred to a different boat for some activities, including kayaking and visiting a floating village.
Karen was still under the weather so she decided to stay aboard the Swan Cruise boat, while the rest of us two-day visitors, got onboard the tender and headed across to another boat which would be taking us around the next few hours.
I was not up for kayaking, so I stayed on board with another couple from the Netherlands while the others set off on the kayaks. About an hour later they came back, and we started to sail again. As we cruised, we had lunch, which was very tasty and plentiful.
After lunch, we pulled up to the jetty and transferred onto some small boats that were rowed by ladies which took us through a sheltered bay among the limestone karst islands.
Dating back thousands of years, Halong Bay has been populated by small local communities living on floating villages tucked away in between the karst, sunken mountains.
Originally built as a place for returning fishermen to sell their fresh catch from the night before, the Halong Bay floating villages became residential quite quickly. People lived, ate, slept, worked, partied, and even went to school in these tiny, self-sufficient floating villages.
But of late things have changed. The government sent out a directive that would force the residents to move inland and leave their floating homes behind.
At first, the people in the village were indignant, refusing to leave behind the homes- the community that they had spent generations to build. But the government’s standpoint was firm: the people’s quality of life, and particularly the children’s access to education would improve vastly if they moved inland. Pollution and environmental protection were also a big factor.
Now, the Halong Bay floating villages are preserved intact, just the way they were when the residents still lived here full time.
Although people do not now live here full time, the locals still carry out a lot of activities and work tasks here, such as fishing, net weaving, and pearl processing.
We were taken through one of these floating villages and saw the people at work, primarily growing clams and harvesting pearls. At the end of our boat journey, we were taken to see a demonstration of seeding the clams and of course, taken into a store selling pearl jewellery.
It was now time to head back to the Swan Cruise ship. While we’d been away Karen had been all the way back to Ha Long port and had been joined by a new group of twenty or so people.
The routine for the rest of the day was the same as the day before with pre-dinner drinks on the deck followed by dinner.
Day Three
Like the day before we got up early so, we could do Tai Chi on the top deck. This time it was being led by our new guide Mike, who had replaced Man the day before when he returned to Hanoi. Mike’s class was better than the last session, with very clear explanations as to what we were doing.
Straight after Tai Chi, we all went down to breakfast. Karen was feeling better, but still under the weather. After breakfast, it was a case of clearing out our rooms and then going on a short hike to visit some caves on one of the islands.
The caves were about 75 metres up the side of one of the limestone karsts via some very steep steps, which some people struggled with a bit. Once inside the caves, the ground was less slippery. There were a few nice formations, including stalactites, flowstones and columns. Infuriatingly some people insisted on sitting on and touching these formations, ignorant that these actions could damage them. I wish the guides would be more active in instructing their clients! After the caves, we climbed back down the steps and headed to the little man-made beach around the corner, which was very cute, for a few minutes. At this time the gloomy weather that had been with us for the last day or so perked up and we got to see glimmers of the sun once more which greatly improved our visibility of the islands in the bay.
Soon it was time to return to the Swan Cruise ship and set sail back to Ha Long harbour.
Once back in Ha Long, we climbed aboard our bus for the three-hour trip back to Hanoi.
