 Off the northwestern coast of Herm is the islet of Le Plat Houmet , and beyond that Fondu , which like Herm belongs to Guernsey . In Belvoir Bay on the eastern side of the island are the islets of Mouliere , situated off Frenchman 's Point which is to the northeast of the manor village , and Caquorobert . To the south of this off the southeastern coast is Puffin Bay , which contains the islet of Putrainez near the coast and the islet of Selle Rocque further out to the south . The far southwestern point of the island is Point Sauzebourge , and Bishop 's Cove is just to the north of this . North of the cove and south along the beach from the harbour and White House are the Rosiere Steps , with a quarry and cottage of the same name in the vicinity . The Mouette and Percee reefs are offshore here . Hermetier , along known as Rat 's Island , lies about 250 metres ( 820 ft ) off the western coast between Fisherman 's Beach and The Bear 's Beach , to the north of the harbour , linked by a low causeway from the beach .
