Los Morrillos Cliffs Reserve offers dramatic coastal cliffs and unique karst landscapes along Puerto Rico’s southwestern shore, attracting visitors with its scenic vistas and diverse ecosystems.
Located on the southwestern tip of Puerto Rico near the town of Cabo Rojo, Los Morrillos Cliffs Reserve is a protected coastal area renowned for its striking limestone cliffs rising sharply from the Caribbean Sea. The reserve features a rugged terrain formed from ancient coral reefs and karstic formations, creating a distinctive geological environment rich in caves, sinkholes, and unique rock outcrops. These cliffs provide vital habitats for a variety of coastal and marine wildlife including migratory seabirds and endemic plant species adapted to the limestone substrate and salty winds. Historically, the area was important to the indigenous Taíno people and later explored by Spanish settlers due to its strategic vantage point and proximity to important maritime routes. Today, Los Morrillos Cliffs Reserve is a prime destination for outdoor enthusiasts who enjoy hiking along trails that trace the cliff edges, bird watching, and appreciating panoramic views of the Caribbean Sea, particularly at the iconic Cabo Rojo Lighthouse which sits atop the cliffs. The reserve’s protected status helps preserve both its unique ecology and scenic aesthetic, making it a favored spot for photographers and nature lovers. Visitors can explore the nearby salt flats and mangrove areas that complement the cliffs' coastal ecosystem, providing additional wildlife viewing opportunities. The reserve’s combination of natural beauty, biodiversity, and historical significance offers a rewarding outdoor experience in a striking seaside setting.
