Cat Ba Island is often seen as the quieter, greener alternative to Ha Long Bay, but travelers who stop here quickly realize it offers much more than peaceful scenery. From limestone karsts and hidden beaches to jungle trekking and floating villages, Cat Ba is a destination where nature, adventure, and local life come together. If you are planning your first trip and wondering what to do in Cat Ba, this guide will help you explore the island beyond the usual checklist.

Explore Lan Ha Bay by Boat or Kayak

One of the best answers to the question of what to do in Cat Ba is to explore Lan Ha Bay, a less crowded extension of Ha Long Bay with equally stunning limestone formations. Unlike the busy cruise routes in Ha Long, Lan Ha Bay feels calmer and more intimate, making it ideal for travelers who prefer a slower pace.

You can join a day cruise or an overnight boat trip departing directly from Cat Ba Island. These cruises often include kayaking through hidden lagoons, swimming in emerald waters, and visiting quiet beaches only accessible by boat. Kayaking is especially rewarding here, as it allows you to glide close to towering karsts and discover caves and small inlets at your own pace.

For a more immersive experience, consider exploring Lan Ha Bay with a local guide. A Tubudd Local Buddy can help you choose the right cruise or arrange a private kayaking route that avoids peak tourist hours, giving you a more authentic connection with the landscape and local fishing communities.

Relax and Swim at Cat Ba’s Beaches

Cat Ba is not only about dramatic scenery, it is also a great place to slow down and enjoy the sea. Cat Co 1, Cat Co 2, and Cat Co 3 are the most popular beaches near Cat Ba Town, each offering a slightly different atmosphere. Cat Co 1 is lively and energetic, Cat Co 2 is quieter and ideal for relaxing, while Cat Co 3 appeals to those staying at nearby resorts.

If you prefer something more secluded, head to Tung Thu Beach or take a boat to less accessible spots around the island. These beaches are cleaner, less crowded, and perfect for swimming or watching the sunset. Visiting early in the morning or late afternoon helps you avoid crowds and enjoy a more peaceful setting.

Beach time in Cat Ba is best combined with other activities rather than treated as the main highlight. The island’s charm lies in balancing relaxation with exploration, making each day feel varied and fulfilling.

Trek Through Cat Ba National Park

For nature lovers, hiking in Cat Ba National Park is one of the most rewarding things to do in Cat Ba. The park covers nearly half of the island and is home to dense forests, diverse wildlife, and panoramic viewpoints. Several trekking routes are available, ranging from short walks to more challenging hikes.

One of the most popular trails leads to Ngu Lam Peak, where you can enjoy sweeping views over the island’s forested hills and coastline. The trail is moderately challenging but manageable for travelers with basic fitness levels. Along the way, you will pass through tropical vegetation and limestone formations unique to the region.

Trekking with a local guide adds depth to the experience, as they can point out native plants, explain conservation efforts, and share stories about life on the island. Booking a Tubudd Local Buddy is especially helpful if you want to explore lesser-known trails and avoid crowded routes.

Discover Local Life and Floating Villages

Beyond natural attractions, understanding local life is an important part of discovering what to do in Cat Ba. Floating fishing villages such as Cai Beo offer a glimpse into a way of life shaped by the sea. These villages have existed for centuries and continue to operate despite the growth of tourism.

Visiting Cai Beo by boat allows you to see floating houses, fish farms, and daily routines that remain largely unchanged. Many tours combine this visit with kayaking or swimming stops, but taking time to observe and learn makes the experience more meaningful.

In Cat Ba Town, local markets are another great place to connect with everyday life. Early mornings are ideal for seeing fishermen bring in fresh catches, which later appear on restaurant menus across the island. Trying local seafood such as grilled squid, steamed clams, or mantis shrimp is a must for food lovers.

Enjoy Adventure Activities and Nightlife

If you enjoy a bit of adventure, Cat Ba offers more than just sightseeing. Rock climbing is increasingly popular on the island, thanks to its limestone cliffs and coastal routes. Several operators provide beginner-friendly courses as well as advanced climbs with sea views.

At night, Cat Ba Town comes alive in a relaxed, social way. Beachfront bars and small pubs create a friendly atmosphere where travelers from around the world gather to share stories. Unlike major party destinations, nightlife here remains laid-back and easygoing, making it suitable for solo travelers and couples alike.

For those who prefer a quieter evening, a sunset walk along the waterfront or a seafood dinner by the harbor is equally enjoyable. The island’s evenings reflect its overall rhythm, unhurried and welcoming.

Practical Tips for Visiting Cat Ba

The best time to visit Cat Ba is from April to June and from September to October, when the weather is pleasant and crowds are manageable. Summer months can be hot and busy, while winter offers fewer tourists but cooler temperatures and occasional fog.

Getting to Cat Ba typically involves a combination of bus, ferry, and boat from Hanoi or Hai Phong. Planning logistics in advance helps reduce travel time and stress. Tubudd Tours can assist with smooth transfers, day trips, and customized itineraries that match your travel style.

When deciding what to do in Cat Ba, focus on quality rather than quantity. The island rewards travelers who slow down, explore mindfully, and connect with local culture. Whether you are kayaking through Lan Ha Bay, trekking in the national park, or sharing a meal with locals, Cat Ba offers experiences that feel genuine and memorable.

If you want to experience Cat Ba beyond surface-level sightseeing, consider booking a Local Buddy through Tubudd. Traveling with a local companion not only helps you navigate the island more easily but also turns your journey into a deeper cultural exchange.
