Outer Brass Island
Outer Brass Island, St Thomas 00802, USVI
Snorkel The Undersea Caves of Outer Brass IslandTantalizingly set at the mouth of Magens Bay, Outer Brass Island tempts exploration. Small and uninhabited, the islet is owned by the USVI Government and is designated as a wildlife sanctuary mainly benefiting a wide variety of sea birds. It’s not 100% off-limits, though—particularly its undersea environs. St. Thomas Scuba and Snorkel Adventures offers excursions to and through a number of underwater caves around the island.
