Larsen Harbour is a narrow inlet right next to Drygalski Fjord, 2.5 miles (4.0 km) west-northwest of Nattriss Head, at the southeast end of South Georgia. Charted by the German Antarctic Expedition, 1911-12, under Filchner, who named it for Captain C.A. Larsen, who was at that time in charge of the Grytviken whaling station.
The area is rat-free, allowing species such as the South Georgia Pipit, and burrowing petrels and prions to thrive. Mountains descend steeply into the sea here, and various glaciers calve into the sea here.
