Grecian Rocks is shaped like a half circle. The reef covers an area about half a mile long, and is inshore from the other reefs in this area. It has beautiful spur and groove coral formations that are covered with colorful corals and sponges. The crest of the reef is lined with fingers of elk horn coral and colorful tropical fish. There are areas where the reef is totally out of the water at low tide.
On the inside of this reef is a sandy flat expanse that is bordered with thick turtle grass areas. This part of the reef is shallow only 3' to 6' deep and there is good chance of seeing Queen Conch. The Conch moves around by motions called leaping and hopping, and is protected. About 75' out from the reef on the south side is an Old Spanish Cannon. It was placed here several years ago by the park service. This dive site is a great one for snorkeling.
