Mare Longue Reservoir is a serene upland lake situated in the central plateau of Mauritius, near the boundaries of the Black River Gorges National Park. Originally constructed as a vital water storage facility and for hydroelectric power, it has evolved into a significant natural retreat surrounded by lush primary forests. The area is characterized by its high rainfall and cooler temperatures, fostering a rich diversity of endemic flora. For outdoor enthusiasts, Mare Longue serves as a starting point or a peaceful stopover for various hiking trails that cut through the indigenous woodland. These trails offer glimpses of the reservoir's tranquil waters and the chance to spot rare Mauritian birds, such as the Mauritius Cuckoo-shrike or the Pink Pigeon. The combination of functional water management and ecological preservation makes it a unique destination, where visitors can enjoy the island's inland beauty and tranquility while exploring one of its most important high-altitude ecosystems.

📋 Practical info

🧭

Getting there

This peaceful upland reservoir is usually accessed via smaller, winding secondary roads branching off from the main Black River Gorges area. Be aware that some final approach sections might remain lightly unpaved.

📅

Best season

The period from May through November is typically considered the best time to thoroughly explore the surrounding primary forest. This smartly avoids the heavy summer tropical rains that drastically muddy the trails.

⛰️

Terrain & paths

The surrounding, beautifully dense primary forest features a complex network of earthen dirt trails. These natural paths can unfortunately become surprisingly slippery and heavily mud-clogged after any recent rainfalls.

🎒

What to bring

Properly waterproofed hiking boots with aggressive grip, lightweight binoculars for excellent birding, and strong insect repellent are highly recommended. A small, easily packable rain poncho is also generally a wise addition.

🅿️

Parking

Modest, informal dirt parking spots are generally found spread out very near the main trailheads leading towards the reservoir's edge. Arriving relatively early in the morning guarantees you a safe and convenient spot.

⚠️

Safety

You must responsibly stick to the clearly visible, established hiking paths within the dense primary forest to completely avoid getting disoriented. Carrying an ample supply of personal drinking water is strictly necessary.

⏱️

Time needed

A thoroughly satisfying hike combined with a rewarding nature and birdwatching session here typically occupies roughly half a day. Longer full-day explorations are easily possible depending entirely on the specific trails chosen.
