    Day by day

    Day 1

    Deer & Lang's cave + bat exodus

    Pick up from Mulu airport and transfer to Mulu Marriot. If you arrive before your room is ready, there is luggage storage available. Have lunch at Mulu Marriott or nearby local restaurants (at own cost) and explore the surrounding area if time permits. At 2pm, transfer to Park HQ to meet your guide and join a 3km walk through the rainforest boardwalk to reach the entrance to Deer cave. A powerful underground river once flowed through this limestone mountain, dissolving and eroding the limestone and leaving a cave passage up to 148m high as well as a perfect profile of President Lincoln in a rock formation within the cave. The sheer size of the cave is awe-inspiring and has to be seen to be fully appreciated! From Deer cave, your guide will take you on to Lang’s cave. Whilst not as large as Deer’s cave, Lang’s cave has some of the most spectacular stalactites and stalagmites in Mulu National Park. After visiting both caves, make your way over to the bat observatory to witness the mass bat exodus around 5.30pm. 12 species of bats have been recorded in the caves, including 2.5 - 3.5 million wrinkle lipped bats. As the sun moves towards the horizon, bat hawks gather on the cliff face awaiting the mass exodus. Most days, the bats will leave between 5.30 - 6.30pm but on some days, they don’t leave at all and you may need to return the following evening and try again - such is nature! After the bat exodus, return to Park Headquarters via the 3km boardwalk trail with a chance to spot nocturnal critters along the way, arriving back around 7 - 7.30pm. Return to Mulu Marriott for an included dinner. Meals - Dinner at Mulu Marriott

    Day 2

    Wind & Clearwater cave + optional night walk

    Depart from Mulu Marriott around 8.45 - 9am and transfer to Mulu Park HQ. Board your traditional longboat for a 20min journey up the Melinau river to Wind cave, making a stop at a Penan handicraft market along the way. On arrival at Wind cave, explore the “King’s Chamber” and forest of stalagmites & stalactites within the cave and learn more about the formation of these incredible geological features. Return to your longboat and continue a few minutes up river to Clearwater jetty. From there, climb 200 steps to reach the main entrance to Clearwater cave system. At 227km long, it’s one of the longest cave systems in the world and home to more of the incredible geological features Mulu is famous for. After visiting both caves, enjoy a simple picnic by the river and take a refreshing dip in clearwater pool. Enjoy another 20min longboat ride back to Park HQ, passing by Penan settlements along the way and arrive back at Park HQ around 1pm. In the afternoon, you can choose to relax at your accommodation, explore the park at your own leisure or join an optional guided tour. Meals - Breakfast & dinner at Mulu Marriott, simple picnic lunch Optional add-ons (chargeable): Night walk or Fast Lane cave (departs daily at 2pm, pre-booking essential) Optional self-guided activities (free): Botanical trail (1.5 - 3km), Tree top tower for birdwatching, Paku Loop trek (8km), Paku Waterfall trek 3km each way

    Day 3

    Optional canopy walk

    Spend the morning at your own leisure exploring the multiple trails in the park before your departure flight to Kuching, Miri or Kota Kinabalu. Meals: Breakfast at Mulu Marriott Optional add-on: The Mulu canopy walk is a 420 metre walkway, suspended 25 metres above the forest floor and is one of the longest tree based canopy walks in the world. As you walk across the treetops, you get a unique "bird's-eye" view of the rainforest and river below. Since not everyone is a fan of heights, this activity is optional. Slots for the Canopy Walk are however very limited and require advance booking, please advise us at the time of booking if you would like to join.

The caves are home to 12 recorded species of bat, including 2.5 to 3.5 million wrinkle-lipped bats, and on most days they leave between 5.30pm and 6.30pm. On some days they do not leave at all and you may need to return the following evening to try again (free of charge), such is nature.

For all cave visits wear non-slip closed footwear such as trainers or hiking shoes, and pack a torch with spare batteries, a water bottle, a raincoat, snacks and insect repellent.
