Sea Walking (underwater walking helmet experience)
Sea Walking is one of the most unique and beginner-friendly underwater activities in the world. It lets you walk on the seabed and explore marine life up close without needing swimming skills or diving experience. In the Andaman Islands, it is a must-try adventure for tourists visiting places like North Bay Island and Havelock Island.
What is Sea Walking?
Sea Walking is an underwater activity where you wear a specially designed oxygen helmet that allows you to breathe normally while walking on the ocean floor.
You walk at a depth of around 7–12 meters underwater, surrounded by colorful fish, corals, and clear blue water.
It is often called:
- Underwater walking experience
- Sea walker helmet diving
- Ocean floor walking
p=ρghp = \rho g h
(Pressure increases underwater, which is why a sealed helmet system is used for safety)
