Adjuntas, Puerto Rico
City of the Sleeping Giant
Adjuntas (ahd-HOON-tahs) is known as the City of the Sleeping Giant, the Land of Lakes, and the Switzerland of Puerto Rico. The silhouette of the “Sleeping Giant” is formed by a mountain range that, when viewed from town, resembles the profile of a reclining person.
Every March, the town celebrates the Festival of the Cidra, dedicated to a traditional local fruit, and in August, around the 21st, the patron saint festivities in honor of Saint Joachim and Saint Anne take place.
Located in the western region of the Cordillera Central, Adjuntas features mountainous terrain and a cool climate, with winter temperatures dropping to the 50s °F (10 °C). It borders Lares and Utuado to the north; Yauco, Guayanilla, and Peñuelas to the south; Utuado and Ponce to the east; and Lares and Yauco to the west.
The nickname Land of Lakes comes from its reservoirs and bodies of water, such as Lago Las Garzas and Lago Guayo, as well as major rivers like the Portugués, the Río Grande de Arecibo, and the Río Grande de Añasco.
In the western part of the municipality lies the Guilarte State Forest, which also extends into Peñuelas, Guayanilla, and Yauco. This high-elevation forest, reaching up to 3,950 feet (1,204 m), is home to native species such as the Sierra palm, caimitillo, and granadillo, as well as introduced eucalyptus.
In the 1980s, the community organization Casa Pueblo emerged in Adjuntas, successfully halting an open-pit mining project that threatened the Cordillera Central. Since then, it has promoted conservation, solar energy, and environmental education projects, and manages the Puerto Rican Biosphere Reserve in the Adjuntas Highlands, which spans 36,000 cuerdas (14,149 hectares) across ten municipalities at elevations between 2,000 and 4,000 feet.
Coffee is an essential part of Adjuntas’s identity. Since the late 19th century, coffee cultivation has been its main economic activity, and local coffee is recognized both inside and outside of Puerto Rico. Other activities include livestock farming, the cultivation of minor crops, and, to a lesser extent, manufacturing.
Together with Utuado and Jayuya, Adjuntas is part of one of the island’s richest mineral zones, with deposits of gold, molybdenum, and copper (chalcopyrite), although exploitation has been limited for environmental reasons.
Adjuntas combines mountainous landscapes, abundant waters, coffee-growing traditions, and a strong community commitment to environmental preservation, making it a unique place to visit and explore.

Rizadas joya de verde aliento,
y mil recuerdos...
