Grand Cayman is the largest island and contains the capital of the caymans islands, George Town. George Town is located at the west end of the island, and running north from George Town is 7 mile beach which is where most of the resort style accommodation for Grand Cayman is located.
Diving on grand cayman can be separated into three separate sections, the northern dive sites, the western dive sites and the eastern dive sites.
Northern dive sites
The northern dive sites are grouped around the north side of the northern sound (a shallow lagoon) where the fringing reef encompasses the sound and then drops into the depths creating the northern wall. The fringing reef has cuts, swim throughs, channels running from the sound out to the deep ocean beyond. The diving available on the northern sites consists of these cuts, swim throughs, channels, the shallow fringing reef, and the spectacular wall drop offs into the depths of the ocean. A large variety of soft corals can be found on the wall, with large pelagics sometimes seen from the wall, and hard corals on the fringing reef itself. Typical pelagics include, southern stingrays, spotted eagle rays, green turtles, hammerhead sharks, black tipped reef sharks. Just on the edge of the northern sound is stingray city and sandbar, two sites where the southern stingrays are commonly hand fed, in depths shallow enough for snorkelers, and all divers to participate in. The hand feeding of the rays has produced very friendly and approachable stingrays for divers to get a close encounter with.
Western dive sites
The western dive sites are the most popular dive sites due to their protection from the weather, little or no current, and excellent visibility. The reef features a spur and grove formation where the spurs run perpendicular to the shore, separated by groves, sandy bottomed channels, that create a labyrinth of swim throughs of which to explore. The west end of the grand cayman is a protected reef area, which means that marine life is plentiful and friendly. Swimming through the reef leads down to a western wall which like the northern wall drops away into the depths of the ocean. Several of the dive sites along the western end of the island are appropriate for snorkelers, and several are also good shore dives.
Eastern dive sites
The eastern dive sites are more exposed to high surf and current from the north eastern trade winds, and are consequently dived less than other sites. The terrain is characterised by large ironside canyons of intricate detail in pristine condition. These large canyons lead out to drop offs into the depths of the ocean, and pelagics are commonly seen from here. The canyons are decorated with swim throughs, caves, gorgonians, black corals, sponges, and soft corals. While there is accommodation at the east end of the island, east end dive operations can be reached as a day trip from the west end of the island by driving.
