Site description Mt Isarog is a large, isolated peak in Camarines Sur Province, on the Camarines Peninsula in southeastern Luzon. The mountain is a dormant volcano that rises to 1,976 m. The vegetation there includes parang grasslands mixed with patches of secondary forest from the lowlands to 900m, lowland forest below about 1,000m, and montane forest above about 900 m,including mossy forest above 1,500 m. However, most of the remaining forest is montane, with closed canopy lowland forests restricted to very steep slopes within a narrow band around 890-1,000 m. There is limited tourism in the area mainly to Malabsay Falls of Naga City and the sulfur hot spring of Hiwacloy. Poor roads and security problems related to insurgency are major factors in limiting tourist numbers.
