Gladden Spit and Silk Cayes Marine Reserve is a protected marine reserve in the central part of Belize's Barrier Reef 22 mi off the coast of Placencia. The reserve contains some of the healthiest parts of the reef system due to its elevation and good water quality.
Gladden Spit is a promontory forming the southernmost tip of the sunken atoll. Three small cayes: North Silk, Middle Silk and South Silk, lie south of Gladden entrance.
It took us about an hour to get to these tiny cayes. Together with other tourist groups, we were based on the South Silk Caye, snorkeling around which was a lot of fun.
