San Juan Islands Scuba Diving Guide

The San Juan Islands have some of the best diving around! The area is very tide and weather dependent and can have poor visibility, but when the conditions are right, the diving is outstanding. Shore access is limited, so it is best if you can go by boat. A community of local divers often meets for shore dives .
