If you are a cave junkie, this is the perfect place to be! The park offers tours to show caves and adventure caves with difficulty levels ranging from low to extreme. But even if you don't like caving, there are other activities you can do to explore and learn more about the rainforest or the Penan tribe. But be sure that you are ready! Bring a backpack, a lot of water, flashlight, raincoat, and non-slippery shoes. If you're interested in the advanced adventure caves, you can get the shoes you need at the gift shop for less than 20 RM.
You will need to arrange everything (accommodation and activities) ahead of time by email. The place was fully booked when we were there, and we were very lucky to be able to have decent accommodation and sign up for the tours in such a short notice.
However, there was a little inconsistency regarding the park rules. The brochure contained information that visitors who wish to book an advanced adventure caving (Clearwater Connection and Sarawak Chamber) should first join the tour to Racer Cave, where they will be assessed by the guides. Only the ones who can provide certificate/membership of international advanced caving groups are allowed to book the advance adventure caves without assessment from park officials. But one of the visitors we met there was allowed to join the Clearwater Connection tour without providing any certificate nor having to complete Racer Cave. Later on we heard from him that he felt he actually wasn't qualified for the tour, because it was too strenuous he could only complete 1/3 of the tour. The park should be more careful in this matter for safety reasons.
But other than that, we had a very pleasant stay and great experience!
