Glide beneath a limestone roof where stalactites hang like natural chandeliers and an underground river leads you through chambers formed over millennia. This day tour from Puerto Princesa pairs a mangrove boat transfer, a guided skiff through the UNESCO-listed cave, and practical field-tested tips to make the most of the experience.

You push off from a dark, narrow mouth where the sea hesitates and the forest leans in. The motor hushes; only the drip of water and the whisper of oars remain as your skiff slides beneath a vault of stone. Light from the cave entrance fractures against mineral columns—stalactites reaching down like chandeliers, stalagmites rising as if answering. For an hour you become a small, watching creature in a subterranean world that has been forming for millennia.

Bring a dry bag

Mangrove and forest fringes can have mosquitoes—apply insect repellent before arrival and after lunch.
