The Bay of Isles is a bay wide and receding , lying between Cape Buller and Cape Wilson along the north coast of South Georgia. It was discovered in 1775 by a British expedition under James Cook and so named by him because numerous islands (at least twelve) lie in the bay. Of South Georgia's 31 breeding bird species, 17 are found here. Named features The features around the Bay of Isles have been charted and named by a number of Antarctic expeditions since 1775. The bay is wide, and has a complex coastline that includes many subsidiary bays, coves, inlets, and other features, many of which have named headlands and points between them. The west coast of the Bay of Isles is roughly C-shaped. Its northernmost point is the rugged headland Cape Buller; Cleveland Rock sits nearby. Pyramid Peak rises over the cape. Just southeast of the cape sits Barlas Bank, a small submarine bank. At the top of the C-shape, Koppervik cove indents the north coast of the west side of the bay, with Breakwater Point marking the cove's west edge. Along the coast to the west are Sheathbill Bay, separated by a small cove from Rosita Harbour. Ram Head separates Rosita Harbour from Camp Bay to the south. In turn, Shag Point separates Camp Bay from Sunset Fjord, which forms the entirety of the southwest corner of the Bay of Isles. Just south of Shag Point within Sunset Fjord is Jock Point. Brunonia Glacier and Clayton Glacier both flow along Murphy Wall into Sunset Fjord. Markham Point forms the west side of Ample Bay, which sits east of Sunset Fjord, along the south coast of the Bay of Isles. Just inside Markham Point is Paul Beach, a shingle beach long. It is tussock-covered at the higher levels, and backed by cliffs which extend eastward from Markham Point. East of the beach, Grace Glacier flows into Ample Bay, marking the west side of Salisbury Plain; Lucas Glacier marks the plain's east side. Continuing east along the south coast of the bay, Luck Point forms the west side of the entrance to Sea Leapord Fjord, a large fjord wide, bordered on the east side by Bellingshausen Point. Immediately east is Beckmann Fjord, whose easternmost side is marked by Daisy Point. Just off the entrance to Beckmann Fjord is Hecate Rock, a submerged rock with a least depth of .
