Once an unexplored cavern located in Barangay Colayo in Bani, Pangasinan, the Nalsoc Cave is a 4-kilometer-long cave with enchanting pools and waterfalls hidden within its hollows, as well as captivating white stone terraces, unique stalactites and stalagmites and seemingly endless hidden chambers. Also nestled within the cave is a subterranean river that empties into the West Philippine Sea. It’s deep enough for seasoned spelunkers to wade in its waist-high waters.
Address: Brgy. Colayo, Bani, Pangasinan
