Mainland Palawan is divided into the west and east coasts by a long mountain ridge that spans El Nido and Bataraza, with highest peaks Mt. Mantalingahan (2,086 MASL) in Brooke’s Point/Rizal area, Mt. Gantung (1,788 MASL) in Bataraza, and Victoria Peak (1,726 MASL) in Narra. The main island is about 425 kilometers long, 40 kilometers at its widest, and 8.5 kms at its narrowest (between Ulugan Bay and Honda Bay, Puerto Princesa City).
Great plains exist, however, in the Bataraza/Brooke’s Point area, Narra, Coron Island and portion of Taytay municipality, generally devoted to rice production. In many areas, however, the mountains begin right from the sea, and would be inappropriate even for habitation. They are great tourism sightseeing destinations though, such as the taraw cliffs of El Nido, Taytay, Coron, and Busuanga, among many.
Four groups of islands comprise the province: Balabac islands in the south, the Calamianes groups in the north, the Cuyo-Cagayancillo group in the east (Sulu Sea) and the Kalayaan group in the west (West Philippine Sea). Palawan is composed of more than 1,700 islands, atolls and islets, ranging from the large mainland to the small, virtually table-size ones that sink underwater during high tide.
With the islands are numerous coral reefs and sunken formations that pose risks to careless nearshore and inshore navigators, but enable the prolific reproduction of fishes and offer great marine underwater vistas to divers and snorkelers.
The province has two climate types: six months each of dry and wet seasons for extreme north and south, and threeto-four months wet season for the rest of Palawan. Typhoons rarely visit Palawan, irregularly once every about 20 years, and much of the early wet season rainfall occurs over the sea.
