When most travelers think of Vietnam’s UNESCO World Heritage Site, Halong Bay quickly comes to mind. With its towering limestone karsts, emerald waters, and iconic views, it’s no surprise that Halong Bay has captured the hearts of millions worldwide. However, nestled just to the south lies a quieter, equally stunning treasure — Lan Ha Bay.

What Is Lan Ha Bay?

Lan Ha Bay is a hidden extension of Halong Bay, located off the coast of Cat Ba Island in Hai Phong Province. While it shares the same geological features — towering limestone cliffs and turquoise waters — Lan Ha remains blissfully less touristy and more pristine than its famous neighbor.

Spanning over 7,000 hectares and dotted with more than 400 limestone islands and islets, Lan Ha Bay is a haven of peaceful scenery, secluded beaches, and lush green forests — a perfect destination for a Halong Bay cruise with a twist.

Why Visit Lan Ha Bay?

1. A Peaceful Alternative to Crowds

Unlike Halong Bay, which can get busy during peak seasons, Lan Ha offers a more intimate and tranquil cruising experience. Fewer boats operate in this area, meaning you’ll often find yourself surrounded by nothing but nature.

2. Hidden Beaches and Crystal-Clear Water

Lan Ha Bay is home to dozens of white-sand beaches, many tucked away between limestone islands. These hidden coves are perfect for sunbathing, swimming, and enjoying privacy you rarely get in Halong.

3. Diverse Activities for Nature Lovers

From kayaking through quiet lagoons and sea caves to swimming in calm, emerald waters — Lan Ha Bay offers all the adventure with none of the crowds. Highlights include:

• Kayaking in Bright and Dark Cave
• Swimming at Ba Trai Dao beach
• Snorkeling or paddleboarding in clear waters

4. Cultural Encounters

Lan Ha is not just nature — it’s also home to traditional floating fishing villages like Cua Van and Viet Hai Village. A visit here gives travelers a glimpse into the rhythms of daily life on the water, untouched by modern tourism.

5. Access via Luxury Cruises

One of the best ways to explore Lan Ha Bay is by boarding a luxury cruise that departs from Tuan Chau Marina or Got Pier. Unlike day trips, an overnight or multi-day cruise gives you time to fully experience the bay’s tranquil beauty, with the added comfort of a well-appointed ship.
