Tips For Kayaking On A Lan Ha Bay Tour Safely

Kayaking is the part of a Lan Ha Bay tour that most guests talk about afterwards. Sliding through a gap in a limestone cliff and coming out into a silent lagoon is something a big boat can never give you. It is also the part of the day where you are most in charge of your own safety: you are low on the water, often in strong sun, sometimes near caves and other boats, and far from a beach with a lifeguard.

The good news is that kayaking in Lan Ha is generally calm, beginner-friendly and very safe when a few simple rules are followed. Our guides have watched first-timers, nervous swimmers and families with young kids paddle happily around the bay. This guide pulls together the safety advice we give before every kayak session: life jackets, tides, sun, cave rules, wildlife, protecting your phone, fitness and kids. For routes, transport and the wider island trip, see our guide to planning a Cat Ba tour from Haiphong City.

Why Kayaking Needs A Little Preparation

Most kayak stops on a Lan Ha Bay tour last somewhere around 45 minutes to an hour and a half. The boat anchors near a group of islands, the crew lowers the kayaks, and you paddle a short loop through lagoons, along cliffs and sometimes through a low cave or rock arch. The water is usually sheltered and flat.

Problems tend to come from small things rather than dramatic ones: a life jacket left unbuckled, a phone dropped overboard, a sunburn that ruins the next two days, a pair of paddlers drifting too far from the group, or a monkey grabbing a snack bag on a beach. Almost all of these are easy to prevent if you know about them before you get in.

Who Can Kayak: Fitness And Experience

You do not need experience to kayak in Lan Ha. Most tours use stable, sit-on-top double kayaks that are hard to tip over, and a guide shows you how to hold the paddle before you start. That said, it helps to be honest with yourself and your guide.

• A basic level of fitness is enough. You will paddle on and off for up to an hour, which is more tiring for the shoulders and arms than people expect.
• If you have back, shoulder or heart problems, or you are pregnant, tell the guide and consider a gentler option such as a rowing boat paddled by a local.
• Non-swimmers can kayak, but should always wear a life jacket and pair up with a confident partner.
• If you are prone to motion sickness, kayaking on flat water is usually fine, but take your tablet before the boat trip, not after.

Pairing matters. Put a stronger paddler at the back of a double kayak, where the steering happens, and a lighter or less confident person in the front.

The Briefing Before You Launch

A good guide will give a short briefing before anyone gets into a kayak. Listen to it, even if you have kayaked before, because it covers the local route and today’s conditions. You should hear where you are going, how long you have, which caves or passages are open at the current tide, where not to go, and the signal to come back.

If you do not get a briefing, ask for one. Ask which direction to paddle, what time you need to return to the boat, and whether there are any areas to avoid. On a busy day, note the colour or name of your boat so you can find it easily at the end.

Prefer to stay in Haiphong and still get on the water? Our Ha Long Bay day cruise is a comfortable way to see the karsts, and many of the same kayak safety rules below apply there too.

Wear Your Life Jacket Properly, Every Time

Life jackets are provided on every reputable Lan Ha Bay tour, and you should wear one from the moment you step into the kayak until you are back on the boat. It is tempting to loosen it in the heat or sit on it as a cushion. Please do not.

• All buckles should be closed and the straps tight enough that the jacket does not ride up over your chin when you lift it by the shoulders.
• Check it is the right size. Ask for a smaller one for children and slim adults.
• If the jacket looks damaged, with broken buckles or torn foam, ask for another.

Even strong swimmers can be caught out by a sudden wake from a passing boat or a bump on a rock. The life jacket is what keeps a small mistake from becoming a serious one.

Understand The Tides Before Entering Caves

Tides make a big difference in Lan Ha. Some caves and rock arches that lead into lagoons are only passable at certain water levels. At high tide, the gap can become too low to fit through; at low tide, the bottom can be shallow and rocky.

Follow your guide’s timing. If they say a cave is closed today, it is for a reason. Inside a lagoon, keep track of time so you are not trying to get back out through a passage as the water rises. If you are unsure whether you can fit, do not try: lean back, keep hands inside the kayak and ask the guide.

Follow Cave And Lagoon Rules

Caves and narrow passages are where most bumps and scrapes happen. A few simple habits keep everyone safe.

• Go through one kayak at a time and wait for the one in front to clear the passage.
• Keep your hands and paddle inside the kayak when passing close to rock. Limestone can be very sharp, and there are often oysters and barnacles on it.
• Duck your head early in low arches rather than at the last moment.
• Do not climb on the rocks or try to stand up in the kayak.
• Keep your voice down in lagoons. Sound carries, and birds nest on the cliffs.

Protect Yourself From Sun And Heat

Sun is the most common problem we see on kayak days, and it is completely preventable. On the water the sunlight reflects off the surface, so you burn faster than you expect, even on a cloudy day. From May to September, the heat can also be intense.

• Apply water-resistant sunscreen before you get in, and again after swimming.
• Wear a hat with a strap or cord so it does not blow away, and sunglasses with a leash.
• A thin long-sleeve top or rash guard protects your shoulders better than sunscreen alone.
• Drink water before you start and bring a small bottle in the kayak.
• If you feel dizzy, nauseous or get a headache, stop paddling, find shade near the cliffs and signal your guide.

Keep Phones And Valuables In A Dry Bag

Every season, our guides see phones go into the bay. Kayaks are wet inside, water splashes off the paddles, and it only takes one wobble during a photo. Do not bring anything you are not willing to lose unless it is properly protected.

• Use a waterproof phone pouch with a lanyard you can wear around your neck.
• Put cash, cards and car keys in a small roll-top dry bag clipped to the kayak.
• Leave passports and anything else important on the main boat with your guide or in a locked bag.
• If you bring a camera, use a strap and keep it in a dry bag between photos. Our photography guide for a Lan Ha Bay tour has more ideas for getting good shots safely.

Respect Monkeys And Other Wildlife

Some kayak routes and beach stops pass near Monkey Island or other places where monkeys live. They are fun to watch, but they are wild animals and can be bold. Do not feed them, do not hold food or drinks in your hands near them, and keep bags zipped and sunglasses on your face. If a monkey approaches, stay calm, do not stare or smile with teeth showing, and move away slowly. If you are bitten or scratched, tell your guide immediately and seek medical advice.

In the water you may see small fish and, occasionally, jellyfish, especially in warmer months. Ask your guide whether jellyfish have been seen that day before swimming off the kayak.

Stay With The Group And Watch For Boats

Lan Ha is quieter than many bays, especially if you follow a Lan Ha Bay route that avoids the crowded spots, but you are not alone. Tour boats, small fishing boats and occasionally speedboats pass through the main channels. Stay close to the cliffs and lagoons where your guide leads you, and cross open channels together as a group, quickly and in a straight line.

If a large boat passes, turn the front of your kayak into the wake rather than letting it hit you side-on. Keep the guide or the group in sight at all times, and if you lose them, stop, stay near the rock wall and wait rather than paddling further away.

Kayaking With Kids On A Lan Ha Bay Tour

Families often ask whether children can kayak. In our experience, school-age kids usually love it, and younger ones can sit in a double kayak with an adult. A few points for parents:

• Check that child-sized life jackets are available before booking, and fit them yourself.
• Put the child in the front seat of a double kayak with the stronger adult behind.
• Keep the session short for young children. Twenty to thirty minutes is often enough.
• Bring a snack and water, but keep food inside a bag if monkeys are around.
• If your child is nervous, a bamboo or rowing boat with a local paddler is a calm alternative.

What To Do If You Capsize

Sit-on-top kayaks rarely tip over in calm water, but it can happen when people stand up, lean out for a photo or hit a wake side-on. If it does, here is what to do, step by step.

• Stay calm. Your life jacket will hold you up.
• Hold on to the kayak and your paddle. The kayak floats and is your best support.
• Check your partner is OK and call or wave to the guide.
• Flip the kayak back over if it is upside down, then climb on from the side, keeping your weight low and pulling yourself across the middle.
• If you cannot get back on, stay with the kayak and wait for help. Do not try to swim to a distant rock.

What To Wear And Bring For Kayaking

• Swimwear or quick-dry clothes you do not mind getting wet.
• Water shoes or sandals with straps, useful for rocky beaches.
• Rash guard or light long-sleeve top, hat with a cord and sunglasses with a strap.
• Water-resistant sunscreen and lip balm with SPF.
• Waterproof phone pouch and a small dry bag.
• A bottle of water and a light snack for after paddling.
• A towel and dry clothes left on the main boat.

How To Pick A Lan Ha Bay Tour With Good Kayak Safety

Not every boat runs its kayak stop the same way, and our essential tips before booking a Cat Ba tour cover the wider checks worth making. Before you book, a few questions tell you a lot about how seriously an operator takes safety on the water.

Questions worth asking before you pay

• Does a guide paddle with the group, or are guests sent out alone?
• Roughly how many kayaks does one guide look after?
• Is there a support boat nearby during the kayak session?
• Are life jackets checked for size and condition, including child sizes?
• What happens if the weather is poor: is the kayak stop shortened, moved to a more sheltered area or replaced?

Clear, confident answers are a good sign. Vague replies, or a promise that “nothing ever goes wrong”, are not.

Best timing for a calm paddle

Mornings are often calmer, cooler and less crowded at popular lagoons, which is why we like tours that schedule kayaking early in the day. In the hot months, avoid paddling in the middle of the day if you have a choice. In the cooler season, the water is chilly, so bring a light windproof layer for the boat afterwards, and remember that storms and strong winds are more common in the typhoon months, roughly July to October.
