Lan Ha Bay Kayaking for Beginners: 2026 Rules, Tips and Safety

From a big tour boat, you see Lan Ha Bay at a distance. From a kayak, you can touch the limestone, hear the water slap against the hull and slip into caves that bigger boats can't enter. Before you plan around it, though, know that kayaking on the Cat Ba bays has been suspended by the local authority since November 15, 2024. This guide to Lan Ha Bay kayaking for beginners covers the current rules, the classic spots and how to stay safe when paddling returns.

1. What makes Lan Ha Bay kayaking special?

Kayaking gets you closer to Lan Ha Bay than any other way of exploring it. The boat is small and light, so it slips into narrow channels, enclosed lagoons and low cave mouths where tour boats have to wait outside.

Update, October 2026: The local authority suspended kayaking on the bays of the Cat Ba Archipelago on November 15, 2024, and extended the suspension on November 27, 2025. Since then, some cruise operators have switched to bamboo rowing boats. Rules can change, so ask your boat operator whether kayaking is allowed on your date before you book, always wear a life jacket and never rent a kayak to paddle out on your own.

Lan Ha Bay, beside Cat Ba Island (often written Catba), covers more than 7,000 hectares and holds around 400 limestone islands. Mountains shelter most of the water, so it's usually calm. That makes it ideal for first-time paddlers, with enough coves and corners to keep experienced kayakers interested.

2. Where do people kayak in Lan Ha Bay?

Many Lan Ha Bay tours stop at the same few paddling spots. Each has its own feel, from the small thrill of entering a cave to an easy drift up to a beach.

2.1. Sang Toi Cave (Dark and Bright Cave)

Sang Toi is the spot everyone talks about. The passage cuts about 70 m through the rock: you paddle through a dark stretch before daylight opens up at the far end. For beginners, it's a good steering exercise. Paddle gently, keep the bow straight and duck where the rock ceiling drops low.

2.2. Luon Cave

Luon Cave leads into a lagoon almost completely enclosed by limestone walls. Inside, the water is still and the breeze is light, so it's a good place to rest your paddle, drift for a while and take a few photos against cliffs draped in green.

2.3. Ba Trai Dao beaches

Ba Trai Dao is a set of three small beaches side by side. After a stretch of paddling, pulling your kayak up onto the sand and cooling off in the clear water is the most pleasant break before you head back to the boat.

3. Should you join a tour or rent a kayak yourself?

If it's your first time on Lan Ha Bay, a boat tour that includes kayaking is the safer choice. Most tours leave from Ben Beo Pier and usually combine kayaking, lunch on board and a swimming stop.

• Half-day tour: About 4–5 hours, usually with one kayak stop. Good for a short schedule.
• Full-day tour: About 7–8 hours, with more time paddling and more stops.
• Private boat: Best for families or groups of friends who want to choose their own stops and how long they paddle.

Some shops around Cat Ba Town and Ben Beo used to rent kayaks by the hour. Since kayaking on the bays was suspended in November 2024, don't rent one to paddle out on your own. If you want to paddle once it's allowed, go with a tour operator and ask which spots are permitted before you book.

Before booking, ask the operator a few questions. Does the price include the bay fee, kayak rental and life jackets? How long is the paddling time, and will a guide paddle with you? Can you change dates or get a refund if the weather turns bad? For reference, the Lan Ha Bay fee since January 1, 2026 is VND 120,000 per adult and VND 60,000 per child aged 6 and over, and children under 6 go free.

4. When is the best time to kayak Lan Ha Bay?

The best kayaking season on Lan Ha Bay runs from April to October. May to July is the most popular stretch, with clear skies and warm water, and September is a good choice too, when the sun softens and the bay is less crowded.

Within the day, early morning and late afternoon bring the calmest water and gentler sun. At midday in summer, the glare off the water is strong, so cover up well or rest in the shade of the cliffs.

On windy days, or when a tropical depression or storm is forecast, trips into the bay may be suspended on notice from tour operators and the authorities. Keep your plans flexible so you can move your day if needed.

5. What do beginners need to know?

Paddling on calm water doesn't take much strength or technique. Learn a few basics and you'll paddle more easily and tire less.

5.1. Single or double kayak?

• Double kayak: More stable, and a good fit for beginners, couples, or parents with older children. The stronger paddler should sit at the back to steer.
• Single kayak: More nimble and easier to maneuver, best for people who have paddled before and want to set their own pace.

5.2. How to hold the paddle and keep your balance

• Hold the paddle with both hands, a little wider than your shoulders, with the curved face of each blade facing you.
• Let your torso rotate with each stroke instead of pulling with your arms alone, so you tire less.
• Sit up straight with your weight low, and avoid standing up or leaning suddenly.
• In a double kayak, paddle in rhythm: the front paddler sets the pace and the back paddler steers.

6. What to bring for a kayak trip

• A hat with a chin strap, sunglasses with a strap and water-resistant sunscreen.
• A long-sleeved sun shirt, with your swimsuit underneath.
• Sandals with a heel strap or water shoes. Flip-flops slip off too easily.
• A dry bag for your phone, wallet and documents.
• A small water bottle, tied securely to the kayak.

7. Lan Ha Bay kayaking safety tips

Safety comes first. Every tour operator has its own rules, so listen carefully to the briefing before you get on the water and follow your guide's instructions. A few general rules are worth remembering yourself:

• Wear a well-fitting life jacket with every buckle fastened for the whole paddle, even if you're a strong swimmer.
• Paddle as a group, stay close to the others and the guide, and don't break away on your own.
• Don't paddle into restricted areas or fish farms, or into dark caves when the tide is rising.
• Keep clear of the main boat lanes. When a boat passes, turn your bow to meet its waves head-on.
• If you capsize, stay calm, hold on to the kayak and signal to the guide.
• Don't paddle after drinking alcohol, when you're exhausted, or when the wind picks up or rain moves in.

8. FAQs about Lan Ha Bay kayaking

When it reopens, a single session is all it takes for Lan Ha Bay kayaking to stay with you: the cool water, the dark inside a cave and a small beach you reached under your own power. Until then, ask about the bamboo boat rides some operators offer, and keep these tips for the day paddling returns.
