A UNESCO World Heritage Site of thousands of limestone karsts rising from emerald water, Ha Long Bay is one of Vietnam's most breathtaking sights. This guide explains how to choose a cruise, when to go and what to expect from a voyage through this natural wonder.
Ha Long Bay lies in the Gulf of Tonkin in northern Vietnam, a few hours' drive east of Hanoi. Its 1,600-odd islands and islets create a labyrinth of jade-green channels, hidden grottoes and floating fishing villages.
For fewer boats and equally stunning scenery, many travellers now choose the neighbouring Lan Ha Bay or Bai Tu Long Bay, which offer a quieter, more serene experience.

The heart of any visit is an overnight cruise, and the choice of boat shapes the whole trip.
Boats range from comfortable to genuinely luxurious. It is worth choosing a reputable operator with good safety standards and smaller passenger numbers.

A typical cruise blends relaxation and gentle adventure. Days are spent kayaking through lagoons, swimming from the boat, visiting caves and floating villages, and simply drinking in the scenery from the sun deck.
Evenings bring fresh seafood feasts, sunset over the karsts and, on some cruises, squid fishing after dark. Sunrise tai chi on deck is a serene way to greet the day among the towering islands.

The best times to cruise Ha Long Bay are spring (March to April) and autumn (September to November), when the weather is dry and the seas are calm.
Winter can be cool and misty, which lends an atmospheric, moody beauty, while summer is warm but carries a small risk of storms that occasionally disrupt sailings. Whatever the season, keep a little flexibility in your plans.

Cruises span a wide range, from affordable comfortable boats to lavish floating hotels, with meals and activities usually included. It is a worthwhile splurge for a once-in-a-lifetime setting.
Most cruises include road transfers from Hanoi, so the bay slots neatly into a northern itinerary. Pack layers for cool evenings, swimwear for the lagoons, and a light rain jacket just in case.
With so many operators and bays to choose from, planning a Ha Long cruise alone can be bewildering. Travelling with a small group means the boat, transfers and timing are sorted, and you simply enjoy the view.
