Your activity starts when your guide picks you up from your hotel in downtown Puerto Princesa. As soon as all the other guests in your group are on board, you'll head to Sabang Beach - the drive is about 90 minutes long. When you arrive at the beach, your tour guide will process the paperwork and will help you get on a motor boat to the Park. You'll be given safety equipment like life vests and helmet before entering the cave. An audio device in multiple languages is also available so you can have more information about the cave. You'll go inside the Underground River and marvel at one of the world's New 7 Wonders of Nature. You'll be riding a paddle boat and will be on a 45-minute trip inside the cave. After this, you'll have lunch at Sabang beach where you'll get to taste sumptuous Filipino delicacies. Do not forget to sample "tamilok" as well. It's a woodworm taken from the bark of dead mangrove trees. After lunch, you'll head to Sabang X. It's quite a hike, so be prepared! The zipline ride is about 800 meters long, and it's over the sea. From there, you'll have a fantastic view of the beach, the forest, and the mountains. After the activity, you'll head back to your hotel.
