Luquillo (Spanish pronunciation: [luˈkiʎo]) is a municipality of Puerto Rico located in the northeast coast, northwest of Fajardo; and east of Rio Grande. Luquillo is spread over 5 barrios and Luquillo Pueblo (the downtown area and the administrative center of the city). It is part of the Fajardo Metropolitan Statistical Area.
The city of Luquillo is 26 square miles and it sits on 12 miles of Atlantic coastline. It is nestled between the blue waters of the Atlantic and the El Yunque National Forest, a rainforest, giving it a diverse and unique ecology. Luquillo marks the beginning of the Northeast Ecological Corridor Nature Reserve which runs down the coast from Luquillo's town square all the way down to the Seven Seas Beach in Fajardo. During certain times of the year, it is not unusual to encounter rare or endangered species of fauna (like the leatherback turtle) while visiting in Luquillo.
Luquillo was founded in 1797 and is known as "La Capital del Sol" (sun capital), "La Riviera de Puerto Rico" (Puerto Rico's riviera), and "Los Come Cocos" (The coconut eaters). The town was named after the Indian cacique Loquillo, who died a few years after the last Indian rebellion in 1513.
Hurricane Maria on September 20, 2017 triggered numerous landslides in Luquillo with the significant amount of rainfall.
Luquillo is located on the northeast coast.
Like all municipalities of Puerto Rico, Luquillo is subdivided into barrios. The municipal buildings, central square and large Catholic church are located in a barrio referred to as "el pueblo".
Barrios (which are like minor civil divisions) and subbarrios, in turn, are further subdivided into smaller local populated place areas/units called sectores (sectors in English).
