My family and I stopped by after the underground river tour. It was well worth the stop. We got to look and walk/climb through caves. (Warning can be very difficult if overweight/bad back/not athletic). Alternatively there's as few things you can do on the ground.
The caves are limestone formations having various structures due to historical amounts of erosion mainly by water. Vugs/fractures exist within the different formations making quite interesting to look at for geology enthusiasts.
The best part was the pipeline for me. Two positions exist: fast ride where you sit and slightly slower one in superman position. Was a little nervous about safety but took my chances. Health and safety standards in Palawan seem to be of a higher standard than other places such as Bali/Phuket.
Ziplining in the rain. Great!
Worth the stop. It is a community driven project.
