Grecian Rocks is a crescent-shaped patch reef about 3/4 mile South-Southwest of Dry Rocks - off the coast at MM 106. There are 12 mooring buoys around the reef designated with the letter "G". The reef runs from North to South and is about 1/2 mile long by 150 yards wide. There is a very well-developed spur and groove system overgrown with a variety of corals, sea fans and a great variety of sponges. The depth of the reef is from 1 to 35 feet. Stoplight parrotfish, princess parrotfish, queen parrotfish, and blue parrotfish, as well as nurse sharks, are all at home in this area. The crest of the reef is very shallow and you should not attempt to snorkle there as you will surely touch the top of the coral. In the white sandy area behind the reef is a home for queen conch. But please remember, in the Florida Keys, it is illegal to disturb the conchs!
