1. Introduction to Monkey Island, Lan Ha Bay

Monkey Island, also known as Cat Dua Island, is one of the most popular stops for travelers exploring Lan Ha Bay near Cat Ba Island. This little paradise gets its nickname because of the playful troop of monkeys that live freely on the island. While the monkeys are the highlight for many visitors, the island offers much more than just wildlife encounters.

2. Where is Monkey Island located?

Monkey Island sits within the heart of Lan Ha Bay, just a short boat ride from Cat Ba Town. The distance is roughly 1–2 kilometers from the mainland, which makes it convenient for both day-trippers and cruise passengers.

What makes its location special is the setting: the island is surrounded by hundreds of dramatic limestone karsts that rise straight from the sea, creating postcard-perfect scenery. Unlike some busier islands in Halong Bay, Monkey Island feels more intimate and less crowded, giving you a closer connection to nature.

This small island combines two unique elements:

• A tropical beach escape: white sand, clear waters, and space to sunbathe or swim.
• Wildlife encounters: a chance to see monkeys in their natural habitat without visiting a zoo.

In short, Monkey Island offers a rare experience where you can enjoy both the beauty of Lan Ha Bay and the excitement of spotting wild animals.
