In Between

A very colorful dive with elephant ear sponges and a lot of crevices/cracks. The 'wall' really starts at 30m deep.

Near Bonni's arch and Northwest point.

Orange Canyon

The site name comes from Bonnie Charles, a famous photographer in Cayman Islands. The dive site is great. There is a small cavern, a mini wall and the arch. A lot of marine life including jacks.

Close to Northwest point

Bonnie's Arch



North west side :)

Northwest Point is also known as North West Point.

Northwest Point

The Doc Poulson was sunk in 1981 and now is covered in great coral growth.  Schools of fish, groupers, and eels are near her as she rests on the relatively empty sandy bottom.

The reef is a better dive than the wreck :)

The Doc Poulson remains close to shore but is not accessible as a shore dive.  It's near Coral Gables. Single pin mooring buoy.
