Camarines Sur is the largest province in the Bicol Region and one of the most populous in southern Luzon. It occupies the central portion of the Bicol Peninsula, with Naga City as its dominant urban center and commercial hub. The province is known throughout the Philippines primarily for two things: the Peñafrancia Marian devotion — one of the largest religious gatherings in Asia — and the CamSur Watersports Complex in Pili, an internationally recognized cable wakeboarding facility.
Bicol's Center
Naga City, though not the provincial capital (Pili holds that role), is the economic and cultural capital of the Bicol Region. It has a university-town character, a commercial district that serves the entire region, and an outsized role in Philippine Marian devotion. Mount Isarog and Lake Buhi are among the province's notable natural features.
The Peñafrancia Festival in September draws an estimated 2 million devotees to Naga City — making it one of the largest annual religious gatherings in Southeast Asia.
The province has two distinct sections: the more urbanized northern corridor centered on Naga and Pili, and the more rural southern municipalities approaching the Ragay Gulf. Lake Bato and Lake Buhi in the southern part are freshwater lakes of ecological and cultural significance to local fishing communities.
The 2024 census counted 2,063,314 people in Camarines Sur, the largest of the six Bicol provinces in both population and land area. It has 35 municipalities and two cities: Naga, the most populous, an independent component city and the province's religious, commercial and cultural center, and Iriga, the center of the Rinconada district. Pili has been the capital since 1955. The province covers 5,497 square kilometers of the central Bicol Peninsula, with the Bicol Plain at its center ringed by Mount Isarog, Mount Iriga and Mount Bernacci, and the mountainous Caramoan Peninsula in the east facing Catanduanes. Its name comes from camarines, the Spanish word for the rice granaries, or kamalig, that early Spanish officials saw everywhere: in 1574 Governor-General Guido de Lavezaris called the land Los Camarines. The Isarog Agta of Mount Isarog are among its earliest people.
