7 Best Things to Do on Cat Ba Island for Travellers in 2025

Introduction on the Best Things to Do on Cat Ba Island

Cat Ba Island is Vietnam’s best-kept secret—tucked just south of the famous Ha Long Bay, but way more laid-back, way less crowded, and just as jaw-dropping. It’s the kind of place where you can hike through jungle one day, kayak past floating villages the next, and still make it back in time for fresh seafood by the beach.

Whether you're solo traveling through Vietnam, backpacking with friends, or looking for a chill escape Hanoi, this island hits the sweet spot between adventure and relaxation. Not sure where to start?

Here are the 7 absolute best things to do on Cat Ba Island in 2025.

1. Cruise or Kayak in Lan Ha Bay

This is easily the top-rated activity on Cat Ba Island. Lan Ha Bay is like Ha Long Bay’s cooler, less touristy cousin—with towering limestone cliffs, secret beaches, and floating fishing villages that feel straight out of a movie.

You can book a half-day or full-day boat cruise, most of which include kayaking, swimming, and lunch. For a closer look, paddle through narrow caves and hidden lagoons. If you're staying at Quiri Hotel Cat Ba, reception can help you book a trusted tour on the spot.

2. Hike to Ngu Lam Peak in Cat Ba National Park

Cat Ba National Park is a UNESCO biosphere reserve and home to one of the best short hikes in Vietnam: the climb to Ngu Lam Peak. It’s only 1.5 km each way but expect a steep, sweaty trail with a huge reward—360-degree views of forested hills and limestone formations stretching all the way to the sea.

Pro tip: Go early in the morning or late afternoon for cooler weather. It’s one of the most satisfying things to do on Cat Ba Island for nature lovers.

3. Relax at Cat Co 1 and Cat Co 2 Beaches

Need a beach day? These two sandy spots are the best on the island. Cat Co 1 is more popular, with lifeguards and places to rent sunbeds. Cat Co 2 is a bit quieter—perfect for a swim, a read, or a beachfront nap.

They’re connected by a gorgeous cliffside trail and just a few minutes Cat Ba Town, so you don’t need a motorbike to reach them. Sunset here is pure magic.

4. Visit Hospital Cave

This might be one of the most unique tourist spots on the island. Hospital Cave is a hidden wartime shelter built inside a limestone mountain. During the Vietnam War, it operated as a fully functional underground hospital, complete with operating rooms and even a cinema.

A local guide walks you through the eerie, echo-filled halls while sharing stories of how it was used. It’s creepy, cool, and a fascinating part of Cat Ba’s history.

5. Take in the Views Cannon Fort

If you’re chasing a jaw-dropping view, Cannon Fort delivers. Perched above the town, this historic military site overlooks Lan Ha Bay, the port, and distant islets. You’ll also see old cannons and war bunkers decades past.

Even if the official fort is closed, there’s a trail nearby that still leads to stunning viewpoints. Bring a cold drink and watch the sun dip behind the karsts—easily one of the best free things to do on Cat Ba Island.

6. Explore Cai Beo Fishing Village

If you want to experience real local life on the water, Cai Beo Fishing Village is a must. Just a few minutes Cat Ba Town, this is one of the oldest floating fishing villages in Vietnam, home to hundreds of colorful houses, boats, and floating fish farms.

The best way to explore it is by kayak or on a guided boat tour. You’ll glide through narrow waterways between floating homes, pass local fishermen tending their nets, and see how people live completely on the sea. It’s peaceful, authentic, and feels worlds away the main tourist spots.

7. Go Rock Climbing or Try Deep Water Soloing

Cat Ba is a climbing hotspot—no experience needed. There are beginner-friendly climbs on dry land, or if you’re feeling bold, try deep water soloing: climb without ropes and drop straight the sea.

Several local companies offer guided trips to some of the island’s best cliff faces. It’s one of the most adventurous things to do on Cat Ba Island and definitely something to brag about back home.
