Dive Site Overview
Exploring Sandy Reef often involves encounters with varied geological features, from the shallow spur-and-groove formations of Sand Key to the more intricate swim-throughs found at sites like Sand Bottom Cave on nearby French Reef. Sand Key, lying roughly six nautical miles southwest of Key West, provides a broad, open experience at depths typically between 5 to 9 meters (15-30 ft).
