Boat Trip Through Halong Bay, Vietnam

If You Are Concerned About Crowds, Skip Halong Bay and Go to Lan Ha Bay Instead

Lan Ha Bay sees fewer than 60,000 visitors a year. Halong Bay, directly adjacent and geologically identical, handles millions. They share the same dramatic limestone karst formations rising from jade-green water, the same caves, the same atmospheric morning mist – but Lan Ha Bay has most of it without the flotilla of tour boats. Lan Ha Bay is reached via Cat Ba Island by ferry from Haiphong; the newer cruise operators here have invested in better vessels and services to compete with the established Halong Bay industry.

That said, Halong Bay itself earns its reputation. The UNESCO World Heritage status is justified. The combination of nearly 1,600 karst islands and islets, cave systems, floating villages, and the experience of sleeping on the water in the middle of it all constitutes one of the more distinctive things you can do anywhere in Southeast Asia. What you are choosing between is the full-volume version or the quieter one.

Getting There

Most visitors travel to Halong Bay from Hanoi, roughly 170 kilometres southwest. The journey takes three to four hours by road. Most cruise operators include transfers from Hanoi in their packages, which is the simplest approach. Public buses and private minivans connect Hanoi to Ha Long City independently. For Lan Ha Bay, the route goes via Haiphong to Cat Ba Island.

What to See on the Water

Sung Sot Cave (Surprise Cave) on Bo Hon Island covers roughly 10,000 square metres across two main chambers and is the largest and most visited cave in the bay. The upper chamber is genuinely impressive at scale. Most cruise itineraries include a stop here.

Titop Island, named after Soviet cosmonaut Gherman Titov who visited with Ho Chi Minh in 1962, has a sandy beach at its base and a 400-step staircase to a hilltop viewpoint. The panoramic view of the bay from the top takes about 20 minutes of climbing to reach and is worth the effort.

Vung Vieng Floating Village is one of the few remaining fishing communities in the bay, with around 200 families living year-round on wooden houses mounted on oil drums. Some cruise operators arrange guided tours that include conversations with local fishermen.

Dau Go Island’s name translates as Driftwood Island, a reference to timber stored here by 13th-century general Tran Hung Dao before a decisive naval battle against Mongol invaders – a detail that adds historical weight to what is already a beautiful spot.

How to Choose a Cruise

Spending at least one night on the water is the defining experience of a Halong Bay trip. Budget wooden junks offer basic cabins with shared bathrooms; mid-range and premium operators provide en-suite cabins, sundeck space, and better food. Choose your operator based on independent reviews, not booking aggregator rankings. Confirm exactly which activities and meals are included before paying, because the gap between cheap and mid-range is significant here in ways you will notice.

Activities

Most cruises provide kayaks as standard, and paddling through the karst formations at water level is the best way to understand the scale of the bay. Dark and Bright caves in Lan Ha Bay, accessible only by kayak at low tide, lead through narrow rock arches into enclosed lagoons. Rock climbing on Cat Ba Island runs from beginner to technically demanding; guiding outfits on the island offer half-day and full-day sessions with gear.

Squid fishing after dinner under lamplight on a quiet anchorage is a low-key activity offered by most overnight cruises. The technique is simple, the atmosphere is pleasant, and the results are unpredictable.

Practical Notes

October through December and March through May are the most popular months. January and February are cooler and mistier but quiet and atmospheric. Bring cash – bar tabs, optional activities, tips, and souvenirs are cash transactions, and ATMs on Cat Ba can be unreliable. Give yourself two nights minimum on the water; that is enough time for the bay to properly work on you.
