The area covers 9.95 km2 (3.84 sq mi) (of which 9.05 are maritime) and was declared a national park 1995, partly as a social defense against increased human activity in the form of time-sharing that would destroy a significant part of the area's mangroves.
The park contains different ecosystems, such as mangrove forests, coral formations, beds of marine grasses, and a small area of tropical dry forest. Due to the colorful coral reefs, the Providencia Island is also known as "The Sea of Seven Colors" (Spanish: El Mar de los Siete Colores). Crab Caye and the Three Brothers Cayes form four small islands that are part of the National Park.
Average yearly rainfall is 3000 mm, with the largest precipitation occurring in October–November. There is a dry period from January to June. Average temperature is 25°C and relative humidity 73.3%.
The mangroves range from 3 m (9.8 ft)–12 m (39 ft) in height. The predominant species is red mangrove and there is also smaller populations of black mangrove and white mangrove.
There are 74 recorded species of bird in the area. Noteworthy marine species include: Audubon's shearwater, magnificent frigatebird, brown booby and royal tern; non-marine: green heron and bananaquit (Coereba flaveola tricolor). The extensive area of marine grasses around the lagoon and bordering mangroves is made up of Thalassia testudinum and Syringodium filiforme.
A visitor centre on Crab Caye is accessible by boat. For conservation reasons, it is not permitted to access the other small islands that form part of the National Park.
