Sarawak Chamber
Sarawak Chamber, Gua Nasib Bagus
The largest known cave chamber in the world, about 600 meters long and 400 meters wide. It is open only to experienced cavers on advanced routes.
The Sarawak Chamber lies inside Gua Nasib Bagus (Good Luck Cave). A British caving expedition discovered it in 1981. It measures about 600 meters long, 400 meters wide, and 80 meters high, making it the largest known underground chamber in the world by area. This is the park's highest-level caving experience. The hike to the cave entrance takes about 3 hours. You wade against an underground river and climb ropes to enter. Inside the chamber, you rely only on headlamps to experience the immense space in the darkness. The round trip takes about 10 to 15 hours. Prior caving experience is required, usually including completion of an intermediate cave, and bookings must be made several months in advance.
