Palawan, Philippines

Palawan is, without a doubt, the Philippines' most beautiful island. It is considered a natural marvel of the Philippines. Palawan's coastline runs about 1240 km. The good news is that Palawan has several undeveloped beaches with crystal pure water.

The Puerto - Princesa subterranean river is one of the world's new seven natural wonders. This 5-mile-long underground river is the world's longest navigable underground river. UNESCO designated the Puerto - Princesa Subterranean River National Park, which preserves this Palawan natural marvel, as a world heritage site in 1999.

Tubbataha Reef Natural Park is another must-see sight in Palawan. This natural park, which covers 13028 hectares and preserves a substantial number of marine species, is a UNESCO world heritage site. Marine turtles and birds may be seen on the park's North islet.

Aside from that, the beautiful Palawan island contains rainforests, mangroves, rivers, streams, lakes, and waterfalls.
