Ugong Rock is one great side trip after visiting the Underground River National Park. Ugong Rock is a 75-foot limestone formation in the midst of farmlands in Barangay Tagabinet, a once sleepy community.
At the start of the course, the guide will tell you why it was called "Ugong". The word “ugong” stands for the reverberating sound (similar to a bell) that stalactites produce inside the cavernous structures of Ugong Rock when hit or pounded with the knuckles or the palm.
The tour in Ugong Rock is actually a climb to the top of the limestone formation. Tourists need to wear a helmet to prevent head injuries while squeezing themselves through holes and cracks, bring along a bottle of cold soda or juice, and protected pockets to prevent the camera from hitting the hard limestone while actively climbing up a steep incline midway in the tour.
