Alligator Reef
Featuring some of the most popular reef dive sites in Islamorada, this incredible reef is marked by a 136-foot lighthouse that was built in 1873 to commemorate the wreck of a Navy schooner. The reef is intermittently sliced with canyon-like channels, called the Gullies, that shelter endless schools of fish in depths from 5 to 60 feet. Guests to Alligator Reef witness a variety of grunts, porkfish, and morays, as well as the occasional, inevitably curious, barracuda.

Cheeca Rocks
Straight out from Cheeca’s namesake resort, the Rocks are the largest of the inshore patch reefs. Ideal for snorkelers, this shallow reef covers several acres, and offers a variety of dive sites in waters with depths ranging from 12 to 15 feet. Known for their diverse marine life, the Rocks host colorful parrotfish, queen triggers, and graceful angelfish, not to mention frequent visitors like spotted rays and schools of tarpon and snook.

The Eagle
Sunk as part of the artificial reef system in 1985, this 287-foot freighter lies in 65 to 110 feet of water on its starboard side and gives divers four decks and cavernous hold to explore. Home to a spectacular array of marine life, this is one of the most popular dive sites in all of the Keys.

Night Dives to Davis Reef
In depths of 25 feet, this coral ledge runs for approximately 300 yards and is famous for its moray eels that greet all divers.

Hens and Chickens
Southeast of Snake Creek Pass, marked with a 35-foot tower and buoy No. 40 on Hawk Channel, lies a beautiful patch reef system named for its unusual coral head formations. With over 10 popular dive sites, the system varies in depths from virtually nothing to over 20 feet. The reef comprises layered star coral heads that are accented with brain corals, seafans, and sponges. Inhabitants include grey snapper, blue stripe grunts, and an occasional docile nurse shark.

The USS Spiegel Grove
A Landing Ship Dock (LSD 32), which is now the largest vessel ever intentionally sunk as an artificial reef. The vessel is 510 feet in length and 84 feet wide. She resides at a depth of 130 feet near Dixie Shoals in Key Largo – lying on her starboard side. About 400 feet of the ship’s length is accessible at a depth of 48 – 50 feet. Most of the Spiegel Grove can be explored at depths of 50 – 85 feet.
