How deep are the reefs? How far offshore are they?
The reefs are located between 3 and 8 miles offshore off the coast of the Florida Keys. Snorkeling tours will typically go to one of the inner reefs. These areas are protected and are shallow; average depth ranges from 5 to 15 feet. The glass bottom boat tour takes you to Molasses Reef which is further offshore, about 6.5 miles; average depth is about 10 to 30 feet. Scuba Tour Depths range from 30 to 45 feet.
