Camarines Sur^{[dead link]}, often shortened to CamSur, is the largest of the six provinces of the Bicol peninsula. It is rich in nature, history, and culture, from the heritage churches of some small towns, to the smallest commercially-bred fish to the pink and black sand beaches of the Partido region.

While there is little in the way of geographical boundaries, CamSur has many distinctive cultures defined by the local variety of the Bikol language being spoken. A rough division of the province for travel purposes is:

Metro Naga (Naga, Pili, Bombon, Calabanga, Camaligan, Canaman, Magarao, Ocampo) - The capital region, where most of CamSur's population is concentrated. Within the region is the mighty Isarog volcano, and the province's only airport.

Northwest Camarines Sur (Del Gallego, Gainza, Libmanan, Lupi, Pamplona, Pasacao, Ragay, San Fernando, Sipocot, Milaor) - A largely rural area with small towns, and a mix of Tagalog and Bikol speakers.

Partido (Caramoan, Garchitorena, Goa, Lagonoy, Presentacion, Sagñay, San Jose, Siruma, Tigaon, Tinambac) - Encompassing the whole Caramoan Peninsula, it has black sand beaches protected by coral reefs.

Rinconada District (Baao, Balatan, Bato, Buhi, Bula, Iriga, Nabua) - A region bordering Albay, it is known for the Rinconada variety of the Bikol languages, Lake Buhi (and the smallest commercially-bred fish) and Mount Iriga.

Partido and Rinconada regions are considered traditional regions, also marked by welcome arches at the highways. Another way of dividing the province is into a western part and eastern part, which is largely based on the degree of Tagalog influence and the dominant local political families holding positions in Congress, the Villafuertes and the Fuentebellas. There has been a proposal to split the province as a remedy to a long-running political feud between the two.

The Naga region is where a lot of business centers are found. Usually the Naga region is known for rapid urbanization, long history, the Bicol river, mount Isarog and Peñafrancia festival. The Naga area also has Calabanga Port, Camarines Sur watersports complex, Ateneo De Naga, Bangko Central ng Pilipinas, Naga Global Business Park, Magsaysay Avenue, Camaligan River Park, Nordia Sports Complex Canaman, Central Bicol State University of Agriculture, IBM, Concentrix, SM City Naga, Robinsons Naga, S&R Naga and large high rise hotels with the tallest one reaching 20 storey.

The Northwest Camarines region is mostly Tagalog-speaking, laid back and rural, with vast plains and hills in its center. Tourist attractions are mostly in Libmanan, Minalabac and Pasacao. The south portion of the region however is different. Municipalities in the southern part of northwest Camarines Sur are becoming bedroom communities of Naga.

With a population of over 2 million and a land area of about 5,500 km² (2,100 sq mi), CamSur is the largest and the most populated of the Bicol provinces. Most of its population is concentrated around Naga, the largest city and commercial center, and the rest on the only other city, Iriga, and the province's many municipalities.

The province is largely flat and dotted with volcanoes like Mount Isarog. Most of Camarines Sur is at the large plain at the center of the Bicol Peninsula. The southwest has Mount Iriga, another volcano, and three lakes, Baao, Bato, and Buhi, all starting with the same name and has lend the name of their respective municipalities. The Partido (or Caramoan Peninsula) has pink or black-sand beaches, rugged terrain, and rainforest.

While CamSur is mostly Bicolano culturally, lingustically and ethnically, some Negrito (Agta) tribes still inhabit the mountains, and Tagalog speakers live near the border with Quezon to the northwest. The Agta were the inhabitants of the province until the first Bikol speakers arrived; now, many of them either live in the forests (especially at Mount Isarog) or have assimilated into the dominant Bicolano culture.

Camarines Sur (along with Camarines Norte) used to be part of a single province. When the Spaniards arrived, they first referred to what is now CamSur as Tierra del Camarines (after the many kamalig or nipa huts), which became part of a larger Partido de Camarines, which would give the common local name of the Caramoan Peninsula. Partido de Camarines was split, soon rejoined as the Ambos Camarines, and during the American era, was again divided into the two present provinces. CamSur's capital used to be Naga (then the city of Nueva Cáceres during Spanish times, after the historic city of the same name in Spain), but has since been moved to Pili to the southeast.

CamSur is home to two major varieties of the Bikol languages: Central Bikol and Rinconada.

Central Bikol, or simply Bikol, the most widely spoken variety of Bikol, is native to the Naga metro area, northwest Camarines Sur, and Partido, and is widely understood throughout the province.

Rinconada Bikol, another major variety, is spoken in the Rinconada District to the southeast, and at the provincial capital at Pili. It is somewhat a blend of southern Tagalog dialects, Waray and Aklanon to the unfamiliar ear, but it has its own alphabet and some sounds not found in most Philippine languages like the schwa (ə), long vowels, and the ɣ (also found in Aklanon, and pronounced similarly to an alternate pronunciation of Spanish g before a, o and u). There are two major Rinconada dialect groups, but there are also dialects in each town, which are not mutually intelligible to each other.

The Agta (Negrito) population had their own languages which are mutually intelligible to the Bikol languages, but have been supplanted by them. Most Agta now speak dialects of Bikol or Rinconada.

Tagalog, usually Tayabasin, is spoken on the border towns to the northwest, and has influenced Bikol spoken in the northwest and Naga.

Albay Bikol, a Bikol variety related to Rinconada in most aspects, is spoken in the eastern parts of the province bordering Albay.

The closest beach to Naga City is located in Pasacao, a primary destination for Nagauenos during the weekend. Pasacao Beach is a very popular beach to the landlocked residents of Naga City.
