At Cayman Marine Lab

Scuba diving with Cayman Marine Lab owner Tom Byrnes offers the best scuba diving in Grand Cayman. We cater to groups, families and individual divers of all ages. We dive the North Wall more than any other dive shop. Come with us to the Kittiwake and even the Cayman Mermaid! We do more "off the beaten path" diving than any other dive shop, we explore places others don't. Don't just dive, Explore! Come try us out and be sure to read what our divers say about us.

Cayman has about 365 dive sites around the islands. Cayman Marine Lab has over a thousand because we will go the extra miles and do the extra work to get you out on pristine reefs, and what a difference it makes - the live cover on these un-dived reefs is amazing! Even when high winds force us to dive on the west side, we make the best of it with drift dives and careful anchor drops. One of our specialties is to trailer a boat to the south side of the island and have it all to ourselves when the rest of the crowd is west. Twenty seven years of searching for new and interesting dives is your ticket to the best Cayman has to offer.

Where We Dive:

North side

The North side offers some of the best diving in Grand Cayman. The North Wall has dramatic walls with the chance of seeing something big, like Eagle Rays and Sharks. Come see us in the summer time when the seas are as smooth as silk.

West side

The West side offers the calm side of Grand Cayman with beautiful walls and shallow reefs. The West side is also home to the Kittiwake Wreck, a must dive for all. West side diving offers the flat calm side diving Cayman is famous for.

South side

The South side offers the most amazing shallow reefs, nearly all have swim through's and tunnels. South is a must for winter time as the seas all always flat calm. South is all so close to the Cayman trench, the deepest part in the Caribbean.
