Ugong Rock is a beginner spelunker’s joy--though people with a fear of tight spaces should opt out. You climb through a maze of tight passages, crawling through the small holes between the rocks, squeezing through tight spaces, and climbing up steep rocks. The caving takes 30-40 minutes and is well worth the effort. At the top of the cave, there are great views of the green terrain below. Then you can go back down through the cave’s maze and rapel down the rocks or, faster!, take a 21-second trip on a zipline. Ugong Rock is located in Tagabinet, Puerto Princesa in Palawan - about an hour’s plane ride from Metro Manila.
