“It’s really impressive seeing the fissure. It looks so calm from the outside but when you look underwater it’s impressive sometimes kinda scary because it is so deep and clear and there are a lot of rocks. But the suit makes you float so it is impossible to sink. The guides were AMAZING!! Loved Anna she explained everything so well and were with us all the time same as Kevin. The process of dressing up is a little uncomfortable and the suit itself is heavy and makes it a little bit difficult to walk in. The first few minutes in the water are extremely cold. Your lips and forehead go…”
