Mulu 2019 Expedition, Sarawak, Borneo

The Mulu 19 Expedition continued the British exploration of the caves of Gunung Mulu National Park, Sarawak, Borneo. The expedition took place between April 18–May 12, 2019, with primary aims to connect caves within the Gunung Mulu massive, specifically within the southern peninsula of Gunung Api. Attempts were made to connect Cave of the Winds, Racer, and Easter Lagangs Caves into the already extensive Clearwater Cave System, which would have resulted in a new system >150 miles in length.
