Deer & Lang Cave Tour at Gunung Mulu National Park

3 minMalaysia

Did you know that Gunung Mulu National Park just recently became a part of the prestigious list of World Heritage Sites? The biodiversity and karst features are only a few of the reasons the national park received this honor. Before the pandemic I was lucky enough to explore this area with my loved ones. In the travel video below we go on the Deer & Lang Tour. This video and tour showcase the largest cave in Malaysia, the famous bat exodus and those fabulous limestones that Unesco loves so much!

The Gunung Mulu National Park is located on the Sarawak, Malaysia side of the island of Borneo in the heart of the jungle! We started our adventure by trekking 3km through the jungle. Thankfully the park constructed wooden walkways for accessibility and ease for the first part of this tour. On our walk we made friends with adorable lizards and curious butterflies while admiring the beauty of Malaysian nature.

Our walk led us to our first cave, Lang Cave. With only flashlights lighting the way, we gazed at amazing stalagmites and stalactites that adorned the cave walls. We were surprised to learn that it takes six months for the rain water to reach into the lower levels of the cave!

Then it was time for the main attraction, the largest cave in Malaysia, Deer Cave! Deer cave has a length of 2,160 m (7,090 ft) and a height of 196.64 m (645.1 ft). Wow! Inside this cave we marveled at the grand entrance opening and met some critters, including a baby fawn roundleaf bat and a huntsman spider!

Our tour ended with a spectacular show of three million bats flying out of the entrance of Deer Cave at dusk. We learned that Deer Cave has about sixteen different species of bats, including the wrinkled lipped bat. All of these bats fly out of the cave together in the evening to collect food. The bats flew in harmony like a flock of birds making their way south for the winter. It was a beautiful sight to witness and lasted half an hour! (Don't worry I only show about one minute of this lovely flying in the Deer & Lang Cave Video).

Overall, trekking through Deer Cave, Lang Cave and seeing the bat exodus at the Gunung Mulu National Park was a once-in-a-lifetime experience that myself, my mother-in-law and my husband were so glad that we got to experience.
