"For a person who is scared of 4 feet of water, this could easily rate as the most adventurous thing I have ever attempted. An Undersea walk sounds very frightening, but it is not. It is fun and the guides ensure that you enjoy each and every minute of the 25 minutes you spend underwater. I would give this 10 stars on a scale of 5 !! The only reason you can skip this is, if you are an accomplished scuba diver. Other than a scuba diver, i doubt that one can ever experience something similar."
