Marabella is a former town in southern Trinidad, between San Fernando (to the south) and Pointe-à-Pierre (to the north). Early 19th-century maps highlighted it as Marabella Junction because of the railway intersection to Williamsville and other central areas. Originally a separate town, it was incorporated into the City of San Fernando in the 1990s. Marabella was home to the Union Park Turf Club (a horse racing venue) later converted to the Manny Ramjohn Stadium, one of the five major stadiums in Trinidad and Tobago, the others being the Ato Boldon, Larry Gomes, Hasley Crawford and the Dwight Yorke Stadium. Nicknamed "The City that Never Sleeps," the city is always active, as its nightlife of food vending and bars goes almost 24/7. Marabella provides a melting-pot for the wide ethnic groups to "lime" and "ole talk". Marabella's location near the Solomon Hochoy highway and Southern Main Road makes accessibility to all parts of Trinidad easy. This accessibility combined with its commercial infrastructure makes Marabella a prime residential area. Today it is referred to as the "Commercial Hub of Southern Trinidad". Marabella, like many other middle-class neighbourhoods in Trinidad, does have a contingent of its population living below the poverty line in areas such as Bay Road and "The Old Train Line". Marabella is also known for its highly skilled sports personnel, among whom are Raphick Jumadeen (West Indies cricketer), Lloyd John (cyclist), Patricia Cheryl Dyette, Horace Tuitt (track and field), Richard Quanchan (national footballer and hockey player), Don Smith, Fitzroy Guiseppi, Roy Harry, and Johnny DePeiza (boxers). It was home to several steel orchestras such as Southern Marines, Scarlet Symphony, Joylanders, Avalons and Combos such as Ancil Wyatt, Magnets, Silhouettes, Jerry Stewart and Psychedelic Sounds. Marabella is also boasts celebrity entertainers, including Jemel the Entertainer and DJ Floops

Pointe-à-Pierre ( POYNT-ə-PEER) is a town in Trinidad and Tobago. It lies north of San Fernando and south of Claxton Bay. It is most famous as the site of the country's largest (and now, only) oil refinery which used to be run by Petrotrin, the state-owned oil company. The town was built for and is populated by employees of the company. Facilities provided for the residents include a primary school, a yacht club and a staff club equipped with a pool, tennis courts and squash courts (and in the mid-1960s an 18-hole golf course and a secondary school, of which only the golf course remains). The oil refinery was originally built by Trinidad Leaseholds Limited (TLL) and expanded by Texaco. It was transferred to Trintoc when the government purchased the land-based assets of Texaco Trinidad Limited, and then incorporated into Petrotrin. The town is also the home of the world-famous Pointe-à-Pierre Wild Fowl Trust, a wildlife reserve for waterfowl located within the secured premises of the Petrotrin oil refinery. Pointe-à-Pierre is separated from Marabella by the Guaracara River and from Gasparillo by the Sir Solomon Hochoy Highway. It lies on the Gulf of Paria and is an important port for the export and import of petroleum products. At the southern edge of Pointe-à-Pierre lies Guaracara Park, known for its cricket matches. The refinery was closed in 2018.

San Fernando, officially the City of San Fernando, is the most populous city and second most populous municipality in Trinidad and Tobago, after Chaguanas. Sando, as it is known to many local Trinidadians, occupies 19 km² and is located in the southwestern part of the island of Trinidad. It is bounded to the north by the Guaracara River, the south by the Oropouche River, the east by the Sir Solomon Hochoy Highway, and the west by the Gulf of Paria. The former borough was elevated to the status of a city corporation on 18 November 1988. The motto of San Fernando is: "Sanitas Fortis" - In a Healthy Environment We Will Find Strength. San Fernando is called Trinidad and Tobago's "industrial capital" because of its proximity to the Pointe-à-Pierre oil refinery and many other petrochemical, LNG, iron and steel and aluminium smelters in places such as Point Lisas in Couva, Point Fortin, and La Brea.

Naparima College (informally known as Naps) is a public secondary school for boys in Trinidad and Tobago. Located in San Fernando, the school was founded in 1894 but received official recognition in 1900. It was established by Dr. Kenneth J. Grant, a Canadian Presbyterian missionary working among the Indian population in Trinidad. The school was one of the first to educate Indo-Trinidadians and played an important and crucial role in the development of an Indo-Trinidadian and Tobagonian professional class. Naparima is derived from the Arawak word (A) naparima, meaning ‘large water’, or from Nabarima, Warao for ‘Father of the waves’. The school was founded in the churchyard of Susamachar Presbyterian Church in San Fernando as the Canadian Mission Indian School. In 1899 the Mission Council petitioned the Board of Queen's Royal College in Port of Spain for affiliation with it. In 1900 the school became a recognised secondary school and was thus eligible for state aid. It was then renamed Naparima College. In 1917 it relocated to its present campus at Paradise Hill on what was then the southern edge of the city.
