Absolutely stunning views underwater. They provide you with a dry suit, snorkel gear, and flippers. They warn you that it is cold (2*C) but the experience is totally worth it! Our guide was great - gave us a little safety briefing and interesting facts about the fissure. They do take some pictures for an extra $20 but I used a go pro and those came out great.
What an awesome...
