El Nido is a first class municipality and managed resource protected area in the province of Palawan in the Philippines. It is about 420 kilometres (260 miles) southwest of Manila city, and about 238 kilometres (148 miles) northeast of Puerto Princesa – capital of Palawan. According to CNNGo, El Nido is the Best Beach and Island destination in the Philippines for its “extraordinary natural splendor and ecosystem”.
Located in Bacuit Bay, El Nido covers a land area of 465.1 square kilometres in the northern most tip of mainland Palawan, is bordered by the Linapacan Strait in the north, the Sulu Sea in the east, and the South China Sea in the west. It is composed of 45 islands and islets, each has its own unique geological formations.
The highest peak is at Cadlao Island, towering up to 640 metres above sea level.
Together with Sulu Archipelago, Sabah, and South China Sea, El Nido, being part of Palawan, is located in the tectonically active and seismically active Sunda Plate, a plate that is entirely separate from the Philippine Mobile Belt to which the rest of the Philippines belongs.
The Permian to Paleogene rocks and limestone cliffs of El Nido are similar to those that can be found in Ha Long Bay in Vietnam, Guilin in China, as well as Krabi in Thailand, all of which are part of the Sunda Plate.
