Caguas

Caguas ( Spanish pronunciation: [ˈkaɣwas], locally [ˈkawaʔ]) is a city and municipality in central eastern Puerto Rico. Located in the eponymous Caguas Valley between the Sierra de Cayey and Sierra de Luquillo of the Central Mountain Range, it is bordered by San Juan and Trujillo Alto to the north, Gurabo and San Lorenzo to the west, Aguas Buenas, Cidra and Cayey to the east, and Patillas to the south. With a population of 127,244 as of the 2020 census, Caguas is the fifth most populated municipality in the archipelago and island and a principal city of the San Juan metropolitan area.

Since 2009, Caguas had the distinction of being the only municipality in Puerto Rico recognized as a Tree City USA by the Arbor Day Foundation, until 2026, when the municipality of Vega Baja was announced as the second in the island to receive it.
