Guayanilla

Guayanilla is an administrative division in southern Puerto Rico, stretching along the Caribbean coast with mountains rising to the north. A flat coastal plain extends toward Guayanilla Bay, which offers a natural harbor.

The municipality emerged on February 27, 1833, when it separated from Yauco through a gubernatorial decree. This division marked an important moment in the development of Puerto Rico's southern communities.

The municipality keeps alive its farming roots through local celebrations where residents gather each December to honor their patron saint with traditional events.

The municipal administration operates from a local office where visitors can obtain information by phone or in person. The region is best explored during drier months when coastal conditions remain more stable for outdoor activities.

The name arose from blending Guadianilla, named after a Spanish river, with words from the Taíno language of the indigenous people. This linguistic fusion reflects the meeting of European and Caribbean cultures in the region's past.
