Patriot Hills Base Camp was a private seasonally occupied camp in Antarctica. It was located in the Heritage Range of the Ellsworth Mountains, next to the Patriot Hills that gave it its name. The camp was run by the private company Adventure Network International (now Antarctic Logistics & Expeditions LLC, known as ALE),a company that provides expedition support and tours to the interior of Antarctica. It was constructed in 1987 and used during the summer months of November to January. Patriot Hills was for many adventurers and explorers a stop on the way from Chile's Punta Arenas into the interior of Antarctica. The flight time from Punta Arenas is about 4.5 hours.
