The entire region was taken for logging in the early 1900s, but while much of the surrounding land was re-planted with fast-growing invasive trees such as eucalyptus from Australia, a portion was left, that naturally re-grew some indigenous Mauritian plants.
The Visitors Centre, just off the A10, contains a display of the biodiversity, forests and invasive species of the country, as a basic overview.
Behind the centre is the arboretum, where over 150 labelled endemic and indigenous species are grown on grassy slopes intersected with paths.
At the bottom of the arboretum is the fernery, where many of the island's critically endangered endemic ferns and orchids are displayed.
Here, several looped trails go through kilometres of gradually recovering indigenous forest, and past a large elevated platform at the park's highest point, from which the surrounding region can be viewed.
