Couva is an urban town in west-central Trinidad, south of Port of Spain and Chaguanas and north of San Fernando and Point Fortin. It is the capital and main urban centre of Couva–Tabaquite–Talparo, and the Greater Couva area includes the Point Lisas industrial estate and the port of Point Lisas. It is one of the fastest-growing towns in the country. Couva's southern boundary is at the village of California and Point Lisas, and to the north Couva stretches to McBean. To the east of Couva is Preysal. To the west of Couva is the road to Waterloo and Carli Bay, which are located on the Gulf of Paria. Couva was part of the Caroni County. Couva is considered a major power base for the United National Congress, whose headquarters was previously located here.

The Borough of Chaguanas is the largest municipality and fastest-growing town in Trinidad and Tobago. Located in west-central Trinidad, south of Port of Spain, north of Couva and San Fernando, and named after the indigenous tribe who originally settled there, it grew in size due to its proximity to the Woodford Lodge sugar refinery. It remained a minor town until the 1980s when it began to grow rapidly as it drew people for its bargain shopping and moderately priced housing. Its rapid growth has seen property values increase dramatically, however.
