Guayacan is a barrio located in Ceiba, a municipality on Puerto Rico's eastern coast in the northern region. The barrio encompasses approximately 11.57 square kilometers and sits within Ceiba's broader landscape, which transitions between coastal areas and inland terrain typical of the eastern portion of the island. The name Guayacan derives from the guayacan tree, native to the tropical landscape of this region, suggesting the area's natural vegetation and rural character.

As part of Ceiba's municipal territory, Guayacan reflects the mixed development patterns found throughout the municipality. The barrio's substantial area relative to its parcel count indicates a landscape with larger land holdings and lower population density compared to urban barrios in San Juan or other densely settled municipalities. Properties in Guayacan are likely to consist of larger parcels suitable for agricultural use, residential development on extended lots, or mixed rural and residential properties typical of eastern Puerto Rico's barrios.

The terrain in this part of Ceiba experiences the tropical climate characteristic of Puerto Rico's northeast coast, with adequate rainfall supporting vegetation growth. The eastern location means the barrio is removed from the capital region but maintains connectivity to Ceiba's municipal center and regional commercial corridors. Owners and investors exploring property in Guayacan will encounter a different development pattern than urban neighborhoods, with more space between properties and land parcels reflecting historical settlement and agricultural patterns.

Propieda maintains property records and cadastral information for parcels in Guayacan, allowing current and prospective owners to access ownership history, parcel boundaries, and CRIM documentation for the barrio.

Ceiba: Ceiba, on Puerto Rico's east coast, underwent transformation after the Roosevelt Roads Naval Station closure. The former base area offers development opportunities, while established areas provide residential options near the Ceiba ferry terminal serving Vieques and Culebra. Natural attractions include beaches and the nearby rainforest.
