A magically clear, blue river that seems to spring from nowhere.

Bohol's mysterious brown hills.

This volcano in the Philippines is believed to have miraculous healing powers.

Hidden deep within a Filipino jungle is an incredible waterfall that plunges into a dazzling blue-green pool.

This belfry is all that remains of the town that was buried by a violent volcano eruption.

This eerie abandoned building with a dark history is said to be one of the most haunted places in the Philippines.

The once-grand remains of this resort are slowly turning into the strange ruins of the future.

This curious fresh and salt water lake holds a secret that draws in deep divers from around the world.

Five miles of underground river link lake to ocean.

Hundreds of wooden coffins dangle from cliffs and caves in the Philippines.

An island in the middle of a lake, in the middle of a volcano, in the middle of a bigger lake, in the middle of a bigger island, in an archipelago, in the Pacific Ocean.

This wondrous waterfall rushing down a green-covered mountain wasn't discovered until 2010.
