Cabo Rojo Salt Flats

Ancient salt extraction site dating to the Taíno period, now a wildlife reserve with brilliant pink ponds

The Cabo Rojo salt flats have been worked continuously since at least 700 CE, making them one of the oldest industrial sites in the Americas. The shallow hypersaline ponds turn vivid shades of pink and orange — tinted by salt-tolerant algae and brine shrimp — and make for striking photography, especially at sunrise and sunset.

The flats are now part of the Cabo Rojo National Wildlife Refuge and managed for habitat conservation as much as salt production. A visitor centre run by local civic group Caborrojeños Pro Salud y Ambiente has displays on the ecology and history. The ponds are excellent for shorebirds; look for black-necked stilts, American oystercatchers, and the endangered yellow-shouldered blackbird. The path through the flats connects to the trail out to the Faro Los Morrillos lighthouse.

A story
The Taíno people were harvesting salt here when the Spanish arrived, making these flats among the oldest continuously operated industrial sites in the Americas. The Spanish quickly recognized the value and took control; the salt trade helped provision ships and preserve food throughout the colonial Caribbean for centuries.
