Introduction to the Ha Long Bay

Set in the emerald waters of the Gulf of Tonkin, Ha Long Bay is often called Vietnam’s crown jewel. This UNESCO World Heritage Site is famous for thousands of towering limestone islands, mysterious caves, and calm turquoise waters. Located about 170 kilometres east of Hanoi, the bay’s name translates to “descending dragon,” and legends speak of divine creatures creating its unique geography.

Our ha long bay travel guide introduces you to this natural wonder while sharing cultural insights and travel tips. We explain why this breathtaking destination deserves a place on your itinerary and how GrandViet Tour can help you experience it comfortably.

Ha Long Bay Travel Guide - Key Highlights

A visit to Ha Long Bay is a journey through geology, biology and culture. The Ha Long Bay–Cat Ba Archipelago World Heritage site covers an area of 65,650 ha and includes 1,133 islands and islets. Many travellers also refer to the wider Ha Long area, which spans roughly 1,553 square kilometres and contains around 1,969 islands. These limestone pillars rise dramatically from tranquil seas, forming one of the planet’s largest marine-invaded karst landscapes.

Highlights of the bay include:

· Otherworldly Karst Formations: Weathered over millennia, these pillars and arches create a seascape that is both rugged and graceful.

· Caves and Grottos: The most famous is Sung Sot (Surprise) Cave with its huge chambers and stalactites. Thien Cung (Heavenly Palace) features colourful rock formations, while Dau Go Cave houses hidden stalagmites and historic graffiti.

· Floating Fishing Villages: Communities like Cua Van and Vong Vieng have thrived on the water for generations. Visiting them offers insights into a maritime way of life.

· Biodiversity: The bay hosts 14 endemic floral species and 60 endemic fauna species, including rare orchids, coral reefs and marine mammals.

· Cultural Legends: The name “descending dragon” stems from a myth in which dragons dropped emerald stones into the sea to form protective islands.

From towering cliffs to hidden lagoons, Ha Long Bay’s highlights prove why it was designated a World Natural Heritage Site.

When to Visit Ha Long Bay?

Ha Long Bay’s subtropical climate allows for travel throughout the year, but each season offers unique advantages:

· Spring (March–May): Mild temperatures (18–25 °C) and clear skies make spring ideal for sightseeing. Flowers bloom on the limestone cliffs, and calm seas are perfect for kayaking.

· Summer (June–August): Expect hot, humid weather (up to 33 °C) with occasional tropical rains. The wet season brings lush greenery and fewer crowds, but storms may disrupt cruises.

· Autumn (September–November): Generally regarded as the best season to visit. The weather is comfortably cool (20–28 °C), skies are clear and emerald seas sparkle.

· Winter (December–February): Cool and sometimes misty. Temperatures drop to 15–20 °C. Morning fog adds a mystical feel, though views can be hazy.

Our ha long bay travel guide recommends visiting in spring or autumn for the best balance of pleasant weather and good visibility. However, each season has its charm and GrandViet Tour can tailor itineraries accordingly.
