\Considered the highest mountain of the province of Cavite, Mt. Pico De Loro (also known as Mt. Palay-Palay) is so called because of a unique rock formation near its summit.  Pico De Loro, in Spanish, means Parrot’s Beak.  It was said that the name was given by Spanish mariners who have used the mountain as a directional landmark whenever their galleons approach the port of Manila through Manila Bay.
