Bonner Beach, Remote beach in South Georgia, South Atlantic Ocean.

Bonner Beach is a small, flat beach on the south shore of Larsen Harbor, in the southeast part of South Georgia. The narrow strip of shore lies below the slopes at the head of the harbor, in the South Atlantic.

The beach was named in 1957 by the UK Antarctic Place-Names Committee after William Nigel Bonner, a biologist who studied Antarctic regions for the Falkland Islands Dependencies Survey. The naming honored his contributions to understanding this remote area.

The name honours William Nigel Bonner (1928–1992), a Falkland Islands Dependencies Survey biologist who worked in the Bay of Isles in 1953–55 and served as sealing inspector in South Georgia in 1956–57. The UK Antarctic Place-Names Committee assigned it in 1957, the same era as the South Georgia Survey mapping of 1951–57.

The beach can only be reached by sea vessel, as there are no land routes and the South Atlantic waters require skilled navigation. Visitors should expect rough conditions and limited landing windows depending on weather and tide.

Bonner Beach is the only place in all of South Georgia where Weddell seals breed, a fact recorded in the scientific literature rather than a seasonal spectacle. The beach was named in 1957 for biologist William Nigel Bonner, who worked in the Bay of Isles in 1953–55 and served as sealing inspector in South Georgia in 1956–57.
