Why go to Halong Bay?
Halong Bay unfolds one of the most striking landscapes on the planet: thousands of karst pinnacles rising from an emerald sea. A UNESCO World Heritage Site, it conjures up a legendary setting where dragons are said to have laid down pearls of jade. The morning mist wrapping the islets heightens this unreal, poetic atmosphere.
The experience is lived above all from the deck of a traditional junk, gliding slowly between the limestone columns. You explore caves adorned with rock formations, swim in hidden coves and paddle a kayak at the foot of the cliffs. Nights on board, under a starry sky far from any light pollution, leave a lasting mark.
Beyond the postcard, the bay shelters floating fishing villages, markets on the water and remarkable marine biodiversity. To escape the crowds, many now prefer Lan Ha Bay or Bai Tu Long Bay, every bit as spectacular but more under the radar. It is a total immersion in an environment shaped by time.

Halong Bay is a safe destination, but the quality of cruises varies enormously from one operator to another.

What to see and do in Halong Bay
- a junk cruise
- the karst pinnacles
- the sea caves
- kayaking between the islets
- the floating villages
Sung Sot Cave
The Cave of Surprises is the largest and most visited in the bay. Its immense chambers hold spectacular limestone formations, set off by coloured lighting. A laid-out path winds through stalactites and stalagmites of evocative shapes. From the elevated exit, the plunging view over the anchored junks is unforgettable.
Ti Top Island
This small island offers one of the finest panoramas of the bay from its viewpoint. A staircase of around four hundred steps leads to the summit, where a 360-degree view opens over the pinnacles. At its foot, a crescent beach invites you to swim in turquoise water. Ho Chi Minh named the site in honour of a Soviet cosmonaut.
Cua Van floating village
This fishing village keeps alive an ancestral way of life lived entirely on the water. Colourful houses, schools and fish farms float with the tides, anchored between the islets. You get around in a rowing boat, often guided by women from the village. It is a moving glimpse into the daily life of the bay's maritime communities.
Lan Ha Bay
The quieter neighbour of Halong Bay, Lan Ha charms with its wild beaches and clear waters. Less visited, it offers an ideal setting for kayaking and swimming at the foot of the cliffs. Its hundreds of green islets form an enchanting labyrinth. It is a prime alternative for those seeking authenticity.
Cat Ba Island
The largest island in the bay, Cat Ba is home to a national park covered in dense jungle. Here you can spot the rare golden-headed langur, an endemic primate threatened with extinction. Hiking trails, beaches and caves complete the offer, while the town serves as a logistical base. It is the ideal starting point for exploring Lan Ha Bay.
Virgin Cave
This cave takes its name from a romantic legend of a fisherman and a young woman turned to stone by waiting. Its vast chambers hold surprisingly shaped formations, including a silhouette resembling a female figure. Less crowded than Sung Sot, it offers a more intimate visit. It often features on two-day cruise itineraries.
How many days, and which itinerary?
A 2-day, 1-night cruise is the ideal format, but 3 days let you explore the quieter neighbouring bays.
