Zipping along a jungle river in a longboat on your way to the caves is not a bad way to start the day. The Wind Cave, named for the cool breezes blowing through it, has several chambers, including the cathedral-like King’s Chamber, filled with dreamlike forests of stalagmites and columns. There is a sweaty 200-step climb up to Clearwater Cave and the subterranean river there. The cave itself is vast: more than 200km of passages have been surveyed so far.
After visiting the caves, you can take a dip in the refreshingly cool waters of a sandy swimming spot.
Tours also include a stop at the riverside village of Batu Bungan , a Penan settlement set up by the government as part of a campaign to discourage their nomadic lifestyle. Locals sell trinkets and handicrafts.
The Wind Cave and Clearwater Cave tour takes about four hours, leaving time for another cave visit in the afternoon.
