Admittedly, our group had a tough time climbing the Rock since it has just rained when we came. The rocks are a bit slippery when WET so bring footwear with good traction. This is not the cause for worry as the locals who manage the attraction will assist you if you experience difficulty climbing and they will also ensure that you safely reach the top.
At the top, you can enjoy the breathtaking view of the landscape and the farm down the zipline, which is a very lush green during rainy season. From the top, the zipline is a very cool ride down with very nice scenery, but it was kind of fast that I was like "too bad it's done already".
Overall, Ugong Rock is a very interesting formation where you can experience two extreme adventures, spelunking and ziplining, all in one location. Maybe you could drop by here from the Underground River if you have spare time.
