Fregate is the most isolated of the granite islands and has the most associations with hidden treasure and pirates. Relics found on the island suggest that pirates took refuge here in the 17th and 18th centuries. Today, the island’s treasure is its abundant flora and fauna, which is monitored and protected by a team of ecologists. Thousands of native plants have been replanted, to encourage the increase in numbers of the endangered Seychelles magpie-robin and the Seychelles white-eye. The island is also home to the world’s only population of the critically endangered giant tenebrionid beetle, as well as numerous giant tortoises. Fregate has seven beaches including Anse Victorin, which has previously been voted as the number one beach in the world.
