We Love to be underwater and there are lots of activities that we do for Certified and noncertified Divers.
Sit underwater in a pool with pure fresh water(no chlorine) surrounded by trees and practice meditation. This activity includes a briefing about safety and another about the basics of meditation. We then practice a few skills before jumping in the water with a surface supplied gas source ( monitored by our staff). Normally each underwater session lasts about an hour and the whole thing can be done in a morning.
How about playing a game of poker underwater? This is most fun with a group of friends and does not require any diving skills, some Poker skill’s help though.
