Black River Gorges National Park

The park is centred on a series of deep ravines carved by rivers flowing down from the central plateau, the gorges so steep and the vegetation so dense that the rivers inside them are effectively hidden from the surrounding highlands, creating an island of wild forest within the island's most developed tourist region, where the sound of traffic from the coastal resort strip disappears within minutes of leaving the car park.

Piton de la Petite Riviere Noire, at 828 metres the highest point in Mauritius, rises at the park's southern boundary and is reachable by a marked trail that switchbacks through increasingly native forest as it gains elevation; the planted pine and eucalyptus of the lower slopes give way to a remnant of the island's original forest that once covered the entire volcanic shield, and the transition is visible not just in the species composition but in the structure of the canopy, which becomes more broken and varied as you climb.

The national park was officially proclaimed on 15 June 1994, making it a relatively recent protected area, and its management by the National Parks and Conservation Service in partnership with the Mauritian Wildlife Foundation reflects the scale of the restoration challenge: much of what now looks like mature forest is in fact regenerated scrubland that has regrown since the 1970s following the cessation of widespread logging, and the native species recovery programmes run continuously to push back invasive privet, Chinese fan palm and introduced ruminants.

Two visitor centres provide orientation and maps; the most developed is at Black River on the park's western boundary, where a short interpretative trail descends to a waterfall viewpoint through a corridor of mature fig and palm trees that demonstrate what the pre-colonial forest structure resembled, and the interpretive signage explains the history of forest clearance and the ongoing efforts to restore connectivity between the remaining fragments of native vegetation.

Approximately 60 kilometres of marked trails traverse the park, ranging from the gentle 1.5-kilometre waterfall loop to full-day hikes to the Piton summit; the intermediate Alexandra Falls trail follows a river gorge for 5 kilometres and is considered one of the most scenically rewarding short walks on the island, passing through a section of the park where the forest is most intact and where the birdlife — including the Mauritius kestrel and echo parakeet — is most active in the early morning.

Four field stations inside the park support ongoing scientific monitoring of endemic bird populations — including the Mauritius kestrel, echo parakeet and pink pigeon, three of the most dramatic conservation success stories in island ornithology — and the wildlife foundation runs regular guided outings that give access to parts of the park not open to general visitors, including the nesting sites of the kestrel which require strict access controls to prevent disturbance during the breeding season.

The park forms part of the UNESCO Biosphere Reserve network, reflecting its dual role as a biodiversity refuge and a managed landscape where human activity and conservation coexist, and the panoramic viewpoints along the park's eastern edge command views across the coastline that are among the most photographed in Mauritius, the dramatic combination of forested mountain, white-water cascade and distant ocean making it one of the few places on the island where the full geographic scale of Mauritius becomes apparent.

It is the largest and most ecologically significant protected area on Mauritius, containing the last substantial remnants of the island's native forest and supporting recovery programmes for some of the world's rarest birds.

The trail network offers everything from accessible waterfall walks to challenging multi-hour ridge hikes, all within an hour's drive of the main tourist resorts on the west coast.

The Piton de la Petite Riviere Noire summit hike provides the only genuinely wilderness experience available without a boat on Mauritius.
