After the results of the global vote organized by the New7Wonders Foundation in 2011 were announced, the selected sites undoubtedly became some of the world’s most popular tourist destinations. Travelers from around the globe began eagerly planning their pilgrimage trips, among which the new seven natural wonders include four sites in Asia. This time, Travel Family is introducing the Puerto Princesa Subterranean River in the Philippines.

The Philippine islands, which had received little attention in the past, suddenly leapt onto the international stage and became famous worldwide after the selection. It has also become one of the new popular destinations for Taiwanese travelers visiting Southeast Asia. Aside from the stalactite formations created by limestone terrain, the most distinctive highlight of the Puerto Princesa Subterranean River National Park is the world’s longest navigable underground river.

The longest underground river also means it serves as a tunnel carved through millions of years of natural history. Along the way, you’ll find various types of rock walls and magnificent limestone formations that showcase the wonders of nature. The cave also harbors rare wildlife. Within this 8.5-kilometer-long tunnel of time, you’re bound to encounter living fossils. The entire journey takes about 45 minutes, allowing you to appreciate this stunning wonder up close.
