Thats amazing. I thought it was going to be a bit grotty or have horrible surroundings or something but that really is something special.
I wish I was a better swimmer. When we were on holiday, our ball got kicked out too far. I went after it (the others just stood there). I managed to just about get to it then had to turn around because I was buggered and for some reason I start to panic somewhat if I think I cant touch the bottom. I threw the ball back but the tide and wind took it too far away. I swam back to shore and gave up. The next day at the beach, I noticed someone standing up just past where I had been and the water was only half way up their torso. Not impressed
