Ha Long Bay and the neighbouring Cat Ba Archipelago are known for limestone islands, sheltered water and boat-based sightseeing. Choose your departure port and itinerary before arranging your journey.
With so much to see, it helps to know where to start. This guide covers the best things to do in Ha Long Bay, with practical tips to plan your trip.
Quick Facts Before You Go
Location: Quang Ninh Province, about 150 km from Hanoi
Travel time from Hanoi: roughly 2 to 2.5 hours by expressway
Best time to visit: spring (March to May) and autumn (September to November)
How long to stay: 1 day is enough for the highlights, but 2 days and 1 night is the best balance
Good to know: single-use plastic is banned in the bay, so bring a refillable water bottle
1. Explore the Caves
Caves are the heart of any Ha Long Bay trip. Each has a different character, so choose based on what you enjoy.
Sung Sot Cave (Surprise Cave) is the largest and most visited cave in the bay. Climb a stairway to find two huge chambers filled with stalactites and colorful lighting. It is busy, so go early if you can.
Luon Cave is different. You don't walk in. You paddle or take a small rowboat through a low arch into a quiet, enclosed lagoon. Whether you can enter depends on the tide.
Me Cung (Labyrinth Cave) is a smaller, quieter cave that feels more intimate than Sung Sot.
2. Go Kayaking Through Hidden Lagoons
Kayaking is the best way to see Ha Long Bay up close. Large cruise boats must stay in deep channels, but a kayak lets you slip between the karsts and into sheltered lagoons. Kayaking is allowed only at designated areas, usually in sessions of around 45 to 60 minutes. Many day tours and cruises include it, but confirm this before you book.
Tip: choose a sit-on-top kayak if you're a beginner, and go in the morning for calmer water and softer light.
3. Climb Ti Top Island
For the classic panoramic photo, climb the roughly 400 steps to the viewpoint on Ti Top Island. The climb takes 15 to 20 minutes, and from the top you see the whole bay fanning out below.
Ti Top also has a small beach, and it is one of the few places in the bay where swimming from shore is officially allowed.
4. Spend a Night on an Overnight Cruise
An overnight cruise is the most memorable way to experience the bay. You wake up surrounded by quiet water and mist, without the day-tripper crowds.
Typical on-board activities include:
Sunset on the sundeck
Vietnamese cooking classes (usually spring rolls)
Night squid fishing
Sunrise tai chi
Cruises range from budget to luxury, so compare cabins, itineraries, and reviews before booking.
5. Visit a Floating Fishing Village
Floating villages show how local families lived on the water for generations. Cua Van is one of the best-known, with a small cultural center and rowboat visits.
These are real communities, so be respectful: ask before taking photos of people, and don't buy souvenirs you don't actually want.
6. Swim and Snorkel
Swimming is only permitted in specific areas of the core bay, with Ti Top the main one. The water is warmest from May to October, and January can drop to around 21°C.
If you want more swimming, consider Lan Ha Bay, just south of Ha Long. It has quieter coves where many cruises let guests swim from the boat.
7. Discover Lan Ha Bay and Cat Ba Island
Lan Ha Bay has scenery similar to Ha Long Bay with far fewer boats. Combine it with Cat Ba Island for a more active trip:
Cycling or hiking in Cat Ba National Park
Visiting Trung Trang Cave
Rock climbing and deep-water soloing
Since 2023, the area has been recognized by UNESCO as the Ha Long Bay – Cat Ba Archipelago.
8. Ride the Queen Cable Car
Back on shore, the Queen Cable Car in Ha Long City carries you across Cua Luc bay to a hilltop park with the Sun Wheel. The ticket was around 380,000 VND for adults in mid-2026. Go at dusk for the best views and city lights.
9. Walk the Bai Chay and Hon Gai Waterfronts
Ha Long City has invested heavily in its waterfronts, giving you good options before or after your cruise. Walk the Bai Chay promenade in the evening, then head to Hon Gai for local seafood.
10. Try Local Food
Don't leave without trying the local specialties:
Bun cu ky: crab noodle dish unique to Ha Long
Grilled seafood: squid, clams, and prawns
Cha muc: hand-pounded squid cake, a Ha Long classic
11. Visit the Quang Ninh Museum
If it rains, the Quang Ninh Museum is a good indoor option. It explains the region's geology, coal-mining history, and culture.
12. Take a Day Trip From Hanoi
Short on time? A one-day trip covers two caves, a kayaking session, and Ti Top Island, though the drive each way is long. If you can spare the time, one night on the water is much more rewarding.
How Much Does It Cost?
Most boat sightseeing is covered by a numbered route ticket. For example, the popular route covering Sung Sot, Ti Top, and Me Cung costs about 250,000 VND per person. Children under 1.2 m (or 7 years old) are generally free, and children aged 7 to 15 get a discount. Prices change, so check the latest fees with your tour operator.
Tips for a Great Trip
Check your route. The route number decides which caves and islands you visit.
Book early in peak seasons and holidays.
Pack smart: non-slip shoes, quick-dry clothes, sunscreen, a dry bag, and a reusable bottle.
Watch the weather. Storms are common in summer. Wind, more than rain, is what usually causes cancellations.
Be eco-friendly. Choose operators that follow environmental rules.
