Palmas is a barrio located within Cataño, a municipality on the northern coast of Puerto Rico across the bay from San Juan. The barrio sits in the metropolitan area of the capital region, positioning it within one of the island's most economically active zones. As part of Cataño's urban and industrial landscape, Palmas reflects the municipality's character as a densely developed coastal community with a mix of residential, commercial, and light industrial uses typical of the greater San Juan metropolitan corridor.

The barrio encompasses approximately 11.77 square kilometers and consists primarily of urban and suburban development. Given Cataño's coastal proximity and historical role as a port and refinery hub, Palmas exhibits the typical property patterns of a developed northern coastal barrio—relatively compact lot sizes, mixed-use neighborhoods, and infrastructure consistent with Puerto Rico's northern metropolitan zone. The terrain in this part of the island is generally flat, and the climate is tropical with consistent warmth and humidity year-round, characteristic of the northern coast.
