Site description Mt Banahaw is an active volcano that rises steeply to 2,177 m. The isolated twin peaks of Mt Banahaw and Mt San Cristobal straddle the border between the provinces of Laguna and Quezon. The most extensive stands of closed canopy forest in Laguna Province are on Mt Banahaw. The forest types include lowland dipterocarp forest on the lower slopes and montane forest above about 900 m, including mossy forest around the peak. On the lower slopes of the mountains there are coconut plantations intensively inter-cropped with fruit trees and areas of kaingin, and the surrounding area is intensively cultivated. The forests are a vital watershed for the surrounding lowlands. The accessibility of this IBA from the towns of Dolores, Sariaya, Tayabas and Lukban makes it as a popular destination for tourists, including mountaineers. It is considered as a centre by the religious denominations of southern Luzon, and is visited by pilgrims.
