Ha Long Travel Guide

A World Heritage bay of over two thousand limestone islands rising from emerald waters — 'Guilin on the sea'.

📍 Destination Overview

Ha Long Bay lies in the Gulf of Tonkin in northern Vietnam and is a world-famous natural World Heritage site. Over two thousand limestone islands and islets rise from an emerald sea in countless fantastical shapes, earning it the name 'Guilin on the sea.' Legend says it was the masterpiece left when a celestial dragon descended to earth. Cruising among the islands, you can explore the stalactite wonders of Thien Cung and Sung Sot caves, and climb the islet by the Fighting Cocks rocks for a full panorama. Staying overnight on a cruise ship — watching the sunset redden the archipelago and stars mirror in the blue water, or paddling a kayak through the floating fishing village — is the quintessential Ha Long experience. This seascape marvel has captivated countless travelers.

The best season for a Ha Long Bay cruise is October to April, when the sea is calm. January to March may bring sea fog that limits visibility, and summer (May–September) can see typhoons, so watch the weather. Most trips are package tours from Hanoi; choose an overnight cruise for the full experience.
