Mount Isarog National Park was declared a national park since 1938, and harbors rainforest, endemic wildlife, waterfalls and is home to nomadic Negrito (Agta) tribes people. Mount Isarog is a large, isolated peak in Camarines Sur Province, on the Camarines Peninsula in southeastern Luzon. It is the highest forested peak in Southern Luzon, and is part of the Bicol volcanic chain, and could still be active although no historic eruptions are known. The volcano has active fumaroles, steam vents and hot springs. The mountain is a dormant volcano that rises to 1,976 meters (6,483 feet) tall. The vegetation there includes parang grasslands mixed with patches of secondary forest from the lowlands to 900 meters, lowland forest below about 1,000 meters, and montane forest above about 900 meters, including mossy forest above 1,500 meters. 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.
Mount Isarog has a rich diversity of flora and fauna. It is home to at least 143 kinds of birds, 15 of which are endemic to Luzon including a sub-species of the Velvet-fronted Nuthatch which is found only in Mt. Isarog. Other species endemic to the mountain are the Mt. Isarog Shrew Mouse, Isarog Striped Shrew Rat, the Isarog Shrew Rat and the Isolated Forest. Rich in diversity, the park harbors 1,300 known species of plants including hardwood trees, mosses, ferns and orchids.
Mount Isarog is located 20 kilometers east of the municipality of Naga and 420 kilometers south of Manila. From any point in the Philippines, you can reach Mt. Isarog by land or by air. From Manila, you can take a six-hour drive going to Naga City or if you opt for a plane, a Naga-bound aircraft would be 30 to 55 minutes. Going to the foot of Mt. Isarog is accessible by jeepney or pedicab. And then you have to continue on man-made trails.
Staying overnight in Mt. Isarog National Park is allowed within the Protected Area Office. Food and accommodations are always available at the foot of Mt. Isarog where pension houses, hotels, and inns are everywhere. There are two resorts located in Barangay Carolina along Paganiban Drive, the road leading to the Park entrance.
