We did it two years ago the end of August. We were on the Nautilus Belle Aimee. It was an amazing trip. Be sure to bring at least a 7 mm wetsuit. I wore a 3 mm full suit with a 5 mm full suit over it and was still cold. Because you are not moving around much, it is difficult to stay warm. We had at least six great whites every time we were in the cage. They come very close to the cage, in fact, close enough to touch. But do not touch them. It was a bucket list trip for us, and worth every penny! They schedule the certified divers into the cages, but you could go in the surface cage whenever you wanted to go. There were two and sometimes three divers in the cage at a time. If you have any specific questions, please feel free to contact me. We love talking about that dive trip!
