Physical Characteristics


Topographical and Hydrological Features

     The terrain of the province is rugged particularly on the western portion where a chain of mountain ranges rise to heights up to 2,086 meters. Except for the wide plain in the north and pockets of big valleys and delta lands along the shore down to the south, the west coast is practically devoid of coastal land and consists mainly of craggy foothills and mountains close to the sea.

     Rivers and streams traverse through the province but the most unusual is the seven-kilometer underground river flowing under limestone rocks and emptying into Saint Paul Bay. The only principal river in the province is Iwahig River.

About 74.07 percent (767.3 thousand hectares) of the total forest land were part of the national parks/game refuge and bird sanctuaries/wilderness areas; 171.8 thousand hectares were established timberlands; 25.4 thousand hectares were civil reservations and 71.4 thousand hectares were established forest reserves.
