Puerto Princesa is the capital of Palawan, Philippines, located 306 nautical miles southwest of Manila. It is said that the city was named after a mythical young woman, and Puerto Princesa certainly lives up to her legendary splendor with miles of pristine beaches and lush wilderness. Be sure to visit the underground river — the longest in the world deemed a UNESCO World Heritage Site. Beachgoers should head to Honda Bay, consisting of several islets that are the best location for snorkeling and island hopping.
