Sarawak Journey to the centre of the earth
Deep in Sarawak’s Gunung Mulu National Park are a series of caves which form part of the world’s largest underground chamber. Expect to be immersed into deep gorges, some still flowing with water and others dry, and witness huge stalagmite columns, helictites and waterfalls. You’ll journey through the jungle to get there where you’ll pass over wooden bridges and perhaps, if you’re lucky, see one of the 3
million strong colony of Wrinkle Lipped bats.
