We did a 3-day 2-night trip, staying in garden bungalow park accomodation and visiting the 4 'show caves': Lang, Deer, Clearwater and Wind. The caves themselves are awesome, especially Deer with its huge scale and Clearwater, with its miles of underground river. Large parts are easily accessible, with a guide, via well maintained walkways. The caves are set in primary rainforest; just walking to and from them and around the area in the evening, surrounded by the sounds of the forest, is a great experience in itself. We booked through Borneo Adventure and had a great guide, Nelson, who was full of interesting information on the caves and the flora and fauna of the forest. Food at the park cafe was good and reasonably priced. There is also a centre with loads of interesting information on the history biology and geology of the park. Mulu is an amazing place, my favourite experience in over 2 weeks travelling in Sarawak and Sabah, and it's a world heritage site with good reason.

I never understood why anyone would find cave tours boring. Pictures really don't do them justice - you need to experience them yourselves. I always thought I'd be disinterested, but this is the third time I'm visiting any kind of caves and I still find them so fascinating. Mulu Caves are even better with their sheer size, I cannot be more amazed! From the bat exodus of the Deer Cave to the underground river in the Clearwater Cave, I really have nothing bad to say about them. Book the tours with the park itself, it's cheaper and the guides are super friendly!

I visited Mulu national park and its caves in December 2018 for 2 days. It is such a gem of a place and a must for anybody travelling to Borneo ! I booked a trip to see the wildlife in the north and wanted to squeeze in a quick visit to the caves, what was supposed to be an extra to my main adventure turned out to be the best part of my holiday. The park is beautifully run and the guides are knowledgeable and extremely friendly. Add it to your itinerary trust me on this!
