El Nido is located about 275km northwest of Puerto Princesa, Palawan’s provincial Capitol and around 480km southwest of Manila. Major tourism commenced in El Nido in 1983 when Ten Knots Philippines, Inc, a Filipino - Japanese joint venture company, opened a divers’ resort on Miniloc Island and an airstrip (Lio airport) at Villa Libertad on the mainland to provide access to the area. Due to its marvelous landscape, its crystal-clear waters and the establishment of tourist and air transport facilities, El Nido quickly became a prime tourist destination. In 1984, the company set up a second resort on Pangulasian Island, and in 1998, the third and largest Ten Knots resort on Langen Island. The Bacuit Archipelago area of El Nido has been established by the Philippine government as a Marine Reserve. The El Nido cliffs & limestone caves are estimated to be 250 Million years old and are the home to countless swallows’ nests used in the Chinese cuisine to prepare the famous birds nest soup. The cliffs tower over clear waters with hundreds of species of tropical fishes and corals and some species of endangered sea turtles. Also the forest around El Nido are host for many species of birds, a large number of which are endemic to Palawan but also monkey, squirrel, bear-cat etc.
