Havelock island in Andaman provides a iety of watersports and adventures to do. One of them is sea walking. The feeling is totally different and you will feel as if you walking on the surface of the Moon.
The best part about sea walking is that people between the age of 7-60 years old can go for it and it is not necessary that you will have to know swimming. Sea walking is one option which is open even for the non-swimmers. The trainers will take you almost 10m deep down the ocean. The walk on the ocean floor will be a totally different experience for anyone.
There are many boats which will take you on board for the walk and there are boats from elephant beach also if you want to go from there.
