Puerto Princesa

Puerto Princesa is a coastal city on Palawan Island in the western Philippines. It's a base for boat trips through the massive limestone caves and underground river of the biodiverse Puerto Princesa Subterranean River National Park. Dive sites are dotted around Puerto Princesa Bay, home to long-nosed dolphins, turtles and rays. Close to the port is the 19th-century Immaculate Concepcion Cathedral.
