Puerto Diablo is a barrio located in Vieques, an island municipality off the eastern coast of Puerto Rico. As one of Vieques's geographic divisions, this barrio occupies approximately 44.63 square kilometers and represents a portion of the island's largely rural and undeveloped landscape. The barrio's name reflects the maritime and historical character of the region, which has long been shaped by its island setting and coastal geography. Vieques itself sits about nine miles east of the main island, making properties here distinct from the urban and suburban markets found in central Puerto Rico.

The landscape of Puerto Diablo is primarily rural and natural, typical of much of Vieques's interior and peripheral areas. The island as a whole features tropical vegetation, modest elevation changes, and limited commercial density compared to municipalities on the main island. This barrio, with its substantial land area, would generally offer the type of property holdings found across rural Vieques—larger parcels of land rather than densely subdivided lots, with mixed use potential ranging from residential to agricultural to conservation-oriented holdings. The terrain and vegetation patterns across Vieques support both small-scale farming and properties suitable for long-term land investment or development with minimal existing infrastructure.
