Halong Bay: 11 Must-Do Experiences (2026 Guide)

The 175 floating houses painted in blue and pink line up sheltered by the rocks of Va Gia, and only the slap of oars breaks the silence. Cua Van, tucked into a sheltered cove of the central bay, works as a cultural memory centre for Halong's fishing communities and was ranked by Journeyetc.com among the 16 most beautiful ancient villages in the world in 2012. The visit happens in a rowing sampan steered by the village women, about 45 minutes to glide past the floating school, the temple and the fish farm. More authentic than Vung Vieng, more arranged for tourists, Cua Van still keeps a real resident population.

You pass under a natural stone arch and the village appears, set on the dark water like a raft of yellow houses. Located in Bai Tu Long Bay, away from the classic circuits, Vung Vieng was founded in the 19th century and is home today to about 300 inhabitants who live from fishing, pearl farming and now a little tourism. The rowing-boat visit lasts an hour and includes the pearl farm, where you watch the nucleus inserted into the oyster. Vung Vieng is the pick for travellers who want to skip the Cua Van crowd and prefer raw authenticity to staging.

The boat leaves the harbour and, within fifteen minutes, the karst pillars rise from the jade water like a stone army. The bay, a UNESCO World Heritage Site since 1994, spreads its 1,133 islands over 65,650 hectares in northern Vietnam. A 2-day / 1-night cruise stays the gold standard: you alternate slow sailing, swimming off the back deck, kayaking between the cliffs, and a night aboard, anchor dropped in a silent cove. Compared to a same-day round trip from Hanoi, this rhythm lets the landscape breathe instead of just crossing it.

A crescent of white sand, translucent water, and behind it a jungle-clad sugarloaf calling for the climb. The island, named in 1962 in honour of Soviet cosmonaut Gherman Titov, who was hosted here by Ho Chi Minh, is just 3.7 hectares but concentrates the DNA of the bay. You swim for an hour on the beach, then climb the 400 to 450 steps to the belvedere for a 360° panorama over the karst pillars, the absolute postcard view. It is the only easily accessible high point in the central bay, which is why every cruise stops here.

After about a hundred steps under frangipani trees, the vault opens onto a mineral cathedral lit in blue and pink. Discovered by French explorers in 1901, Sung Sot Cave covers more than 10,000 m² on Bo Hon Island, 25 metres above sea level. The route follows a marked 500-metre corridor through two successive halls, the second large enough to hold a football pitch. It is the most spectacular cave in the central bay, more impressive in volume than Thien Cung further west.

The ferry docks, you cross the fishing port, then the road dives into a dense jungle where langurs call. Cat Ba is the largest island in the archipelago, included in the 2023 UNESCO extension, and its national park, created in 1986, covers 109 km² of land and 52 km² of sea. It is the only worldwide sanctuary of the golden-headed langur, of which fewer than 70 individuals remain, observable from the marked hiking trails (3 to 5 hours depending on the loop). Unlike a classic cruise where you sleep aboard, Cat Ba lets you mix hiking, beach time and evenings in town.

The paddle slices through opal-coloured water, you slip between two 80-metre cliffs, and suddenly a hidden lagoon opens up, empty of any boat. South of Halong, Lan Ha lines up more than 400 islets and 139 sand beaches, without the mass tourism of the main bay. The kayak outing lasts 2 to 3 hours and usually goes through the Ba Ham lagoons and the Dark and Bright caves, paddled through when the tide allows. Lan Ha is the choice for those who have already seen Halong in pictures and want the intimate version, with no buses or queues.

You enter through a narrow fissure, then the space explodes into three successive chambers where stalactites trace dragons, birds and figures from local mythology. Set on Dau Go Island, 4 km from Bai Chay port and 25 metres above the sea, Thien Cung covers nearly 10,000 m² with ceilings rising to 30 metres. The visit takes about 45 minutes, the time it takes to climb the steep path then cross the three chambers in a ballet of coloured lights. More theatrical than Dau Go right next door, this is the cave you pick for the wow factor with the family.

The cross-bay cable car lifts two giant gondolas above the channel, and the entire bay suddenly spreads out through the windows. Opened in 2017 on 214 hectares of Ba Deo Hill, Sun World Halong combines amusement park, Japanese garden and the Sun Wheel reaching 215 metres above the sea, with a 20-minute full rotation. You come for the panoramic view over the karst pillars at sunset, more than for the rides themselves. It is the dry-land alternative for travellers who do not want to board a cruise, or the side trip from a night in Bai Chay.

Sometimes called 'Halong in miniature', this island packs the best of the bay into 3.8 km². Bo Hon is home to Sung Sot Cave, Luon Cave that you cross in a rowing boat, the Drum Cave (Trong) and Dong Tien Lake ringed by cliffs. Most cruises spend a full half-day here, alternating the Sung Sot walk and the rowing-boat passage through Luon, a natural tunnel that opens onto a closed lagoon populated by macaques. Bo Hon is the geographic hub of the central bay: if you only have one day, this is where 70% of the highlights are concentrated.

Natural light filters through the 17-metre-wide entrance, coating the walls with mosses and ferns, a rare sight in a Halong cave. Dau Go covers 5,000 m² on the island that bears its name and takes its name from General Tran Hung Dao, who is said to have hidden here in 1288 the sharpened wooden stakes later planted in the Bach Dang River to trap the Mongol fleet. The visit takes about thirty minutes, on a circular route with a sea-view belvedere on the way out. It is the most botanically alive cave in the bay, where Thien Cung is mineral and theatrical.
