More than 300 kilometres worth of passages make up the Mulu Caves complex which also includes one of the world’s largest cavern passages, Deer Cave (which can fit London‘s St Pauls Cathedral inside it five times over.).

The Mulu Caves began to form over five million years ago when running water began to forge a path between the limestone and sandstone of the mountain’s interior and is continuing to grow in the same way, slowly developing as rivers carve their way through the underground cathedrals and redistribute the limestone from the walls and floors to the tips of the stalactites.

Millions of bats live in the complex and in the evenings they depart on mass in a cloud of flapping wings, to feed.

To enter the cave system you can either walk along a long wooden bridge walkway just off the ground through an ancient forest and limestone flats or go on a longboat trip to the lower caves.

Most of the system is accessible only to experienced cavers, but four caves have been set up as show caves with good lighting and easy access.

Comments, reviews and questions by other travellers

Hi, I just came back from Mulu 2 days ago...You can stay in the National Park (Rm180 per room - can fit in 4 person) or dorm which is much cheaper.

Can you come for a day trip? I don't think so, flight from Miri its either late morning or afternoon and last flight out is before 5pm. So you need to stay over night.

Getting to Mulu cave, cost and expectations

HI,I am planning to take a group of 5 people to visit Mulu cave.

Lastly what do one need to bring for this trip? Thanks if you can help with informations regarding my concerns.
