Palawan: Puerto Princesa, Underground River

One of the New Seven Wonders of the World, The Puerto Princesa Underground River is one of the hottest tourist destinations in the Philippines today.
The tour inside the cave is about 45 minutes.
The cave has amazing rock formations, although it can only be seen by a spotlight from the boat, or by using flash through your camera. With Bats all around here, you are prohibited to look up, with your mouth wide open. Hahaha.

The deep water was so calm even though the sea that connects to this river was raging with waves.
