4.00The view of the Tectonic plates and the clear water plus the pictures make it all worthwhile. Just know that the Changing area is not warm or private and after you are done waiting out in the cold and rain put a damper on the experience We were the last group of the day and all the other workers left so only the 2 guides were left which made standing in the cold rain more unpleasant
Wonderful

5.00A bit chaotic, but definitely organized chaos. Everyone knew what they were doing and everyone was super helpful. Never felt unsafe once.
Best snorkeling trip I have done.

5.00Hanna and the team were the best guides and tenders. Timing just wasn’t right for me to scuba so I snorkeled and had the best time. Go early so you have clear water.
Wonderful experience
