Los Morrillos (Cabo Rojo)

Los Morrillos de los Cabos Rojos (Spanish for "the little promontories of the red capes") or more commonly known as Los Morrillos de Cabo Rojo, is a cape and tombolo landform located in southwestern Puerto Rico in the municipality of Cabo Rojo. Los Morrillos is an excellent example of a tombolo, or a tied island, with two sand pits. The cape resembles a letter Y with its two promontories or morrillos being connected through sand pits which enclose a saltwater lagoon. The landform was designated a National Natural Landmark in 1980 (as the Cabo Rojo National Natural Landmark), and the site includes mangroves, beaches, important bird nesting areas, limestone caves, cliffs and rock formations. The reddish-colored limestone cliffs give the name to the town and municipality of Cabo Rojo.

The Los Morrillos Lighthouse (or Cabo Rojo Lighthouse) is a prominent historic landmark located in the landform. The site is located in and administered by the Boquerón State Forest and the Cabo Rojo National Wildlife Refuge.
