It's a great trip! We where all alone for the whole trip, something that really added to the tranquility of the experience. We got to see Delacour's langur up close, several unique birds and a trip inside the cave, even if it was high water. It was very hot, but we had hats and a good sunscreen which is a must, as well as water. We had our private guide that helped us in explaining what the boat rower had of knowledge. No tipping needed, but we added a bit anyway at the end.
For us, this was a must do and a highlight.
