They have lots of wood benches for getting ready to dive. They offer fish food for the fish which are fun to feed. They also offer a deep side for technical dive training. They have air and nitrox on site to fill tanks

This site is well set-up for divers with no close access to the ocean. The location offers camping, snacks, and air fills to keep any happy diver close to the water. Water temperatures can heat up quite well (> 75) in the summer, but they...More
