Deer Cave, Gunung Mulu National Park

#1 of 9 in Things to do in Gunung Mulu National Park
Deer Cave attracts thousands of visitors every year with its unique rock formations, including the one at its south entrance that resembles the profile of Abraham Lincoln. The cave was opened for public in 1984, and it was long regarded the world's largest cave passage. It is home to three million bats you can watch twirling and swarming outside the cave from the park's bat observatory. The walk to the cave through a tropical rainforest via a 3 km (1.9 mi) plank is an attraction in its own right.

  • A surprise as to how well organized this park is. You need to take a passport to register for the entrance. I visited with 1 guide just for me which gave a great freedom. The walk of about 50 minutes to the grotto, can be more if you find some animal or plant more out of the ordinary by the way, is made on a wooden footbridge in a dense rainforest, crossing some beautiful streams. The grotto is of inexplicable grandeur, fit 2 cathedrals of St. Paul in there, and that leaves us speechless. Although it is the address of thousands (or millions?) of bats, it is not noted the typical smell of ammonia. Given its enormous height in the vast majority of the route, you don't get the feeling of claustrophobia. The visit to its interior, made in cement tours, is "Uaus!". One of the high points, if not raining, is the exit, around the 17:30, of thousands and thousands of bats from the grotto, something truly impressive.

  • Deer Cave is one of those places that you will never forget for the rest of your life. The breadth and depth of the place is mind-boggling. To make life easirer for tourists, the boardwalks have been constructed throughout the cave (at the least the areas that are open to leisure visitors). Illumination at key locations within the cave is excellent. It can be pretty wet and humid inside the cave as might be expected. Highly recommended for anyone visiting this part of the world.
  • A comfortable observatory has been erected at a reasonable distance to watch the squads of bats swirl around the cave of the entrance prior to taking off in search for the night.
