About the Seawalking tour on Koh Samui

Welcome to the Sea walking tour on Koh Samui! Sea walking is considered as the safest ‘underwater sport’ around. It is available to anyone in any age group. Can you breathe? Can you walk? Than you can surely do a Sea Walk! The surroundings around Koh Samui are amazing and there are still many spots where you can enjoy the underwater life. No need to go to Koh Tao, try it here first!

For the sea walking tour no training is required. We have the largest underwater program on Samui with high safety standards and insurance. Sea Walking is not only fun to do, it’s also wonderful educational experience. Learn about the mysteries of the underwater world, while you are being part of it. Are you a non-diver or even non-swimmer or you wear glasses? Don’t worry, you can still join us and enjoy walking on the bottom of the sea , a truly non-gravity environment. This tour runs every day.

How does it work?

It’s pretty easy! We prepare a custom made helmet so your head stays dry at all times. The helmet is connected to the boat above, which means you have a constant air supply. This way you can breathe as you would above the sea!

Sea Walking is a great day trip for: families, couples and kids – the minimum age is 7. Non-divers & non-swimmers: no worries! You don’t need any previous experience. Join us for a trip by traditional Long Tail boat to the wild side underneath the water!

This tour is suitable for anyone: you don’t have to be able to dive or even swim. If you don’t feel like seawalking you can also go snorkeling on site. We provide the snorkeling equipment.


The seawalking tour on Koh Samui takes you south of the island. There is a short 10 minute boat trip to the seawalking site. On arrival, we explain you how it works. You put on your helmet (we have it already in your size), check your breathing and slowly enter the water. The amazing thing is that you can keep breathing while going down to the bottom. We don’t go deep and our staff is always around to check on you. Enjoy the seawalk and underwater life!


If you have had enough of seawalking, or just don’t want to do it, you can still join this tour. The location is very suitable for snorkeling as well! We have the snorkeling equipment on board, which means you can jump in whenever you want. Put on your mask, enter the water and take a look around at the amazing marine life there. You are free to do whatever you want!

Enjoyable trip for me and my wife. Even though there isnt many coral left, the south of samui still has a lot to see under water. Being able to breathe amd checking the surroundings is a must do :)
