The island is dominated by the Allardyce Range, a chain of mountains that runs down its spine, the highest peak being Mount Paget, which stands at 2,935 meters (9,629 feet). These mountains aren’t just for show—they play a huge role in the island’s geography, with glaciers feeding into valleys and fjords, some of which extend deep into the island’s interior. Over half of South Georgia’s surface is covered by glaciers, ice fields, and permanent snow, giving the island its characteristic wild and frozen appearance.
Along the coast, you’ll find a mix of deep fjords, narrow bays, and steep cliffs that plunge directly into the Southern Ocean. These fjords—like Cumberland Bay and Stromness Bay—are key to the island's ecosystem, offering protected areas where wildlife thrives. The coastline is constantly reshaped by the harsh weather and ocean currents, making it one of the most dynamic parts of South Georgia.
South Georgia’s location, between the Antarctic Convergence and the Southern Ocean’s nutrient-rich waters, creates an ideal environment for marine life. Cold waters from the south mix with warmer northern currents, and this meeting point fosters the massive amount of krill, fish, and squid that sustain the island’s large populations of seals, penguins, and whales. Despite its isolation, South Georgia’s unique geography supports one of the most concentrated areas of wildlife on Earth.
The island’s remoteness means there’s very little human impact on its natural geography, allowing South Georgia’s wild terrain to remain almost completely untouched, apart from a few abandoned whaling stations scattered along the coasts. It’s a land of extremes, where glaciers meet ocean, mountains rise straight from the sea, and weather patterns shift rapidly, making it as beautiful as it is unpredictable.
