The refuge supports a tropical island flora and fauna representative of the most healthy coastal resources viewable in Puerto Rico today.

The absence of development in refuge units protects fragile marine ecosystems from damage by erosion and sedimentation, helping to keep surrounding waters clear.

While our trust resources benefit, visitors can enjoy spectacular views both above and below the water line.

The refuge is comprised of lands on the main island of Culebra and 22 smaller islands in the same vicinity.

The refuge contains diverse habitats including sub-tropical dry forest, mangroves, salt ponds and grasslands.
