Moderate – you should be comfortable with sustained uphill walking and some uneven footing.
Tuck away from Mauritius’s beaches and climb into Black River Gorges’ native forest: a three‑hour guided loop that visits the Bats Valley, tops out at 400 m with west‑coast views, and finishes with a river swim. Read on for what to expect and how to prepare.
The trail begins in a humid hush: leaves drip with recent spray, roots crisscross the path like the hands of an old farmer, and the forest seems to breathe around you. Within minutes the island’s everyday noise — scooters, markets, the distant surf — falls away and the canopy takes charge. You climb through a mix of endemic ebony and dodo-era shrubs, breath fogging in the cooler understory, and the guide points toward a narrow cleft: Mare aux Joncs Gorge, the so-called “Bats Valley,” where a cloud of Mauritian fruit bats hangs from branches and flutters like a living curtain.

Begin at first light for cooler temperatures, clearer views and the best chance to see endemic birds active along the ridge.
Roots and wet rocks are common on this route — sturdy hiking shoes with good tread reduce slip risk on the ascent and descent.
Pack light swimwear and a quick-dry towel to enjoy the river pool near the trail’s end after the hike.
Observe the Mare aux Joncs (Bats Valley) from a distance and avoid loud noises or flash photography that can stress roosting fruit bats.
Black River Gorges National Park was created to protect the island’s remaining upland forests and endemic species, preserving terrain shaped by ancient volcanic flows.
The park is a focus of reforestation and invasive-species control; visitors should stick to paths, avoid feeding wildlife and carry out trash to reduce impact.
Provide traction on wet roots and rocky sections; avoid sandals.
Hydration is essential in tropical heat and on exposed ridgelines.
Short, heavy showers are common—pack a breathable waterproof layer.
