Cat Ba Island things to do: The complete 2026 travel guide
What you need to know before going
The biggest story on Cat Ba in 2026 is the Sungroup development project. This massive resort and casino complex is reshaping the southern end of the island. Construction is concentrated around Cat Ba Town, the main harbor area where most visitors arrive.
Here is what this means for your trip:
- Noise and dust. Heavy machinery operates daily from 6 AM to 6 PM. The main road through Cat Ba Town is partially blocked in several sections.
- Blocked views. The harborfront, once a pleasant walking area, is now fenced off with construction barriers.
- Accommodation impacts. Hotels in Cat Ba Town suffer from noise and dust. Many have reduced rates, but the savings are not worth the disruption.
The good news is that the rest of the island remains unaffected. The national park, Lan Ha Bay, and the quieter villages operate as they always have. The key is to choose your base carefully and avoid spending daylight hours in Cat Ba Town.
Pro tip: Book accommodation in Hung Son, Xuan Dam, or Viet Hai Hamlet. These areas are far from the construction and offer better access to nature.
Is Cat Ba Island worth visiting in 2026?
Yes, but with clear caveats. Cat Ba offers genuine value for travelers who want to escape the packaged Halong Bay experience. The island provides:
- Quieter kayaking in Lan Ha Bay with similar limestone karst scenery
- Real hiking through a national park that sees a fraction of Halong's crowds
- Lower prices across accommodation, food, and tours
However, Cat Ba is not for everyone. If your priority is a polished resort experience with white sand beaches and full-service amenities, consider Phu Quoc Beyond the Resorts: Local Beaches, Markets & the South Coast or Nha Trang in 2026: Is Vietnam's Beach Capital Still Worth It?.
If you want the classic Halong Bay cruise experience without the crowds, consider Travel to Ha Long Bay: a complete guide to Vietnam's legendary seascape or Why Ninh Binh Crushes Halong Bay for a Truly Quiet Escape.
Cat Ba is best for independent travelers who want to kayak, hike, and explore on their own terms. The construction is temporary. The natural beauty is permanent.
Best time to visit Cat Ba Island
| Season | Weather | Crowds | Pros | Cons |
|---|---|---|---|---|
| Spring (March-May) | Warm, 22-28°C, low rain | Moderate | Best hiking weather, clear bay views | Occasional afternoon showers |
| Summer (June-August) | Hot, 28-35°C, high humidity | High | Swimming season, long daylight hours | Heat, crowds, potential storms |
| Autumn (September-November) | Cool, 20-26°C, low rain | Low | Perfect kayaking, empty beaches | Shorter days |
| Winter (December-February) | Cool, 15-20°C, drizzle | Very low | Lowest prices, no crowds | Cold swimming, grey skies, some tour cancellations |
The sweet spots are spring and autumn. March to May offers the best hiking conditions with moderate temperatures and low rain. September to November provides excellent kayaking weather with calm waters and clear skies.
Avoid Vietnamese public holidays if possible. Tet (January-February) and National Day (September 2) see domestic tourism spike. Accommodation prices double and ferries sell out.

How to get to Cat Ba Island from Hanoi
Four main options connect Hanoi to Cat Ba. Each has different trade-offs.
| Mode | Duration | Cost (VND/USD) | Best for | Downsides |
|---|---|---|---|---|
| Bus + ferry combo | 3.5-4.5 hours | 200,000-350,000 ($8-$14) | Budget travelers, first-timers | Fixed schedule, crowded |
| Private car + ferry | 3-4 hours | 1,500,000-2,500,000 ($60-$100) | Groups, comfort seekers | Expensive for solo travelers |
| Motorbike + ferry | 4-5 hours | Fuel + 100,000 ($4) ferry | Adventurous riders | Long ride, road risks |
| Scenic public ferry via Halong | 4-5 hours | 250,000-400,000 ($10-$16) | Scenic views, independent travelers | Limited departures |
Bus + ferry combo (most common): Book a combined ticket from Hanoi's Old Quarter to Cat Ba Town. The bus takes 2.5 hours to Got Pier. The ferry takes 30-45 minutes. Then a short bus ride to Cat Ba Town. Total journey: 3.5-4.5 hours.
Warning: Touts at Got Pier may try to sell overpriced ferry tickets or direct you to specific bus companies. Buy only from established operators. Confirm your ticket includes the entire journey.
Scenic public ferry via Halong: This route departs from Tuan Chau in Halong City and passes through Halong Bay. The ferry takes one hour. The views are spectacular. This option requires getting to Halong City first, which adds complexity.

Where to stay on Cat Ba Island
Avoid Cat Ba Town in 2026. The construction noise and dust make it a poor choice. Instead, consider these alternatives:
Hung Son: A village 3 km from town. Quieter, with local restaurants and easy access to Cat Co beaches. Guesthouses cost 300,000-600,000 VND ($12-$24) per night.
Xuan Dam: A rural area on the eastern side of the island. Home to mid-range bungalows and eco-lodges. Prices range from 400,000-1,000,000 VND ($16-$40). Good for couples and families.
Viet Hai Hamlet: A remote village inside the national park. Accessible only by boat or hiking trail. Basic homestays cost 200,000-400,000 VND ($8-$16). Perfect for hikers and nature lovers.
National park area: A few lodges near the park entrance. Basic but quiet. Prices similar to Viet Hai.

Things to do on Cat Ba Island
Kayak Lan Ha Bay
Lan Ha Bay is the quieter neighbor of Halong Bay. The limestone karsts are identical. The crowds are not. Kayaking is the best way to explore this area.
Rent kayaks from floating houses in the bay. Prices range from 150,000-250,000 VND ($6-$10) per hour. Most tours include kayaking in their itineraries. Independent kayakers can launch from Cat Co beaches or Tung Thu Beach.
Best spots to explore: Dark and Bright Cave, Three Peaches Beach, and the floating fishing villages. Tide awareness matters. Some caves are only accessible at high tide. Check local conditions before setting out.
Pro tip: Bring a dry bag for your phone and camera. The water is calm but splashes happen. Reef-safe sunscreen is recommended. Standard sunscreen damages coral.
Hike Cat Ba National Park
The national park covers half the island. Trails range from easy to challenging.
| Trail | Difficulty (1-5) | Duration | Distance | Guide needed? | Best for |
|---|---|---|---|---|---|
| Ngu Lam Peak | 3 | 1-2 hours | 2 km | No | Panoramic views, quick hike |
| Viet Hai Village | 2 | 3-4 hours | 8 km | Recommended | Flat terrain, village visit |
| Frog Lake | 4 | 5-6 hours | 12 km | Required | Remote wilderness, wildlife |
Ngu Lam Peak: The most popular trail. A steep climb through forest to a viewpoint overlooking Lan Ha Bay. Start early (before 8 AM) to avoid heat and crowds. Bring water. The trail has no shade in the final section.
Viet Hai Village trail: A flat walk through the forest to a remote village. The trail is well-marked. A guide is recommended to learn about local plants and wildlife. The village has a small homestay and restaurant.
Frog Lake trail: A challenging hike through dense jungle. Requires a guide for navigation and safety. The trail is muddy after rain. Bring sturdy shoes, long pants, and plenty of water. The lake itself is small but the journey is the reward.

Visit Hospital Cave
A three-level underground hospital built during the American War. The Viet Cong used it as a secret medical facility from 1963 to 1975. The cave has 17 rooms including operating theaters, a cinema, and living quarters.
What you will see: Mannequins in medical uniforms, preserved equipment, and the original concrete structures. What is missing: Detailed information panels. The exhibits are sparse. Reading up on the history beforehand or hiring a guide enhances the experience.
Entrance fee: 40,000 VND ($1.60). Open daily 7 AM to 5 PM.
For more war history sites, see The DMZ from Hue: Vinh Moc Tunnels, Khe Sanh & the Truth About Vietnam War Tours.
Explore Cannon Fort
A hilltop fortification used by Japanese, French, and American forces. The main attraction is the 360-degree view over Lan Ha Bay and Cat Ba Town. Go for sunset. The light transforms the karst landscape.
The fort itself has old cannons, bunkers, and a small museum. The exhibits are minimal. The view is the point. Bring a drink from the cafe at the top. The walk up takes 15-20 minutes from the road.
Entrance fee: 40,000 VND ($1.60). Open daily 7 AM to 7 PM.
Discover Trung Trang Cave
A well-lit cave with a 300-meter walkway through limestone chambers. Stalactites and stalagmites in various formations. Easy access with stairs and handrails. Good for families and rainy days.
Entrance is included with the national park ticket (40,000 VND / $1.60). The cave is 30 minutes from Cat Ba Town by motorbike.
Visit the beaches
| Beach | Crowd level | Water quality | Facilities | Access |
|---|---|---|---|---|
| Cat Co 1 | High | Good | Restaurants, loungers | 10-min walk from town |
| Cat Co 2 | Medium | Good | Basic | 15-min walk from town |
| Cat Co 3 | Low | Good | None | 20-min walk from town |
| Tung Thu | Low | Excellent | Local only | 15-min drive from town |
| Chut Chit | Very low | Excellent | None | 30-min drive from town |
Cat Co 1, 2, and 3 are close to Cat Ba Town. Cat Co 1 is the most developed with restaurants and loungers. Cat Co 2 and 3 are quieter. All three suffer from construction noise during the day.
Tung Thu Beach is the local alternative. Clean water, fewer tourists, and a relaxed atmosphere. A motorbike is needed to reach it.
Chut Chit Beach on the west side is nearly empty. The road is rough. The effort is worth it for solitude.

Take a boat tour or cruise
Day tours from Cat Ba Town visit Lan Ha Bay and sometimes Halong Bay. Prices range from 400,000-1,000,000 VND ($16-$40) depending on the itinerary and group size.
What to look for:
- Small groups (under 15 people)
- Responsible practices (no littering, respectful wildlife viewing)
- Included kayaking and lunch
- English-speaking guide
Overnight cruises cost 1,500,000-3,000,000 VND ($60-$120) and include meals, activities, and cabin accommodation. These offer a more relaxed experience than the rushed day tours.
Warning: Some operators advertise "Halong Bay" tours that only visit the edge of the bay. Confirm the exact route before booking. Lan Ha Bay is similar in scenery and less crowded.
Rock climbing at Butterfly Valley
The Hive is a rock climbing center with routes for intermediate and advanced climbers. The limestone cliffs offer bolted routes up to 30 meters. Difficulty ranges from 5.8 to 5.12.
Gear rental is available but limited. Experienced climbers should bring their own harness, shoes, and belay device. The center offers guided climbs for beginners.
Cost: 300,000-500,000 VND ($12-$20) for a half-day session. Open daily 8 AM to 5 PM.
Visit Monkey Island
The reality check: The monkeys are aggressive. They steal food, bags, and anything shiny. Keep your distance. Do not feed them.
The island has a basic beach and a challenging hike to a viewpoint. The beach is fine for swimming. The hike takes 30-40 minutes through scrub and rocks. The view at the top is good but not exceptional.
Alternative: Skip the monkeys entirely. Visit the island for the beach and hike only. Or skip the island altogether and focus on Lan Ha Bay.
See the Cat Ba langur
The Cat Ba langur is one of the most endangered primates in the world. Fewer than 70 individuals remain in the wild. They live in the national park's limestone cliffs.
Responsible viewing requires a guided trek with a park ranger. The langurs are shy and easily disturbed. Do not approach them. Do not use flash photography. Do not share location details online.
Conservation efforts are ongoing. Supporting responsible tours helps fund protection programs.

Where to eat on Cat Ba Island
Cat Ba's food scene is modest but authentic. Seafood dominates the menus. Local specialties include:

Street food highlights: Fried banana carts near Cat Co beaches. Local markets in Cat Ba Town and Hung Son.
Pro tip: Quality varies wildly in tourist-heavy areas. Restaurants with English menus and laminated photos tend to serve mediocre food. Look for places where locals eat. The plastic stool joints are usually the best.

Getting around Cat Ba Island
Motorbike rental: The best option for exploration. Rental costs 150,000-250,000 VND ($6-$10) per day. Check brakes, tires, and lights before riding. Roads are narrow and sometimes unpaved. Wet conditions make them slippery.

What to skip on Cat Ba Island
The artificial beach development: A man-made beach near Cat Ba Town that charges entrance fees. The water is murky. The setting is artificial. Skip it.
Overpriced Halong Bay cruises from Cat Ba: Some operators charge premium prices for tours that barely enter Halong Bay. Confirm the exact route before booking. Lan Ha Bay is cheaper and equally beautiful.
Tourist-trap restaurants on the main strip: Places with English menus and waiters waving menus at passersby. The food is overpriced and mediocre. Walk one street back for better options.
Aggressive harbor touts: Ignore people offering "special deals" on tours, accommodation, or transport. Book through established operators or your accommodation.
