Puerto Princesa Subterranean River National Park, Puerto Princesa

Voted one of the new seven wonders of nature and listed as a World Heritage Site, Puerto Princesa Subterranean River National Park is reportedly the longest navigable underground waterway on earth. The area is a designated national park and home to the diverse wildlife of bats, reptiles, primates, sea snakes, and other marine creatures. You may run into monkeys and komodo dragons resting in the lush vegetation that surrounds a small blue lagoon at the cave's mouth. Hop on a boat and embark on a journey down the river, winding through a massive cave. See sleeping bats and stalactites hanging from the ceiling like shreds of petrified drapery. In 2010, geologists discovered another level inside the cave with small waterfalls and a large dome rising 300 m (980 ft) above the water.
