2. About Trou de Fer
What Makes It Special?
- Height: 300 metres – one of the tallest waterfalls on the island.
- Location: Salazie, a lush cirque in the central highlands of Réunion (coordinates -21.038142, 55.553105).
- Geology: The waterfall drops into a deep, volcanic gorge that earned the site its name. The surrounding cliffs are composed of basaltic rock, a reminder of the island’s fiery origins.
A Brief History
Trou de Fer has long been a landmark for the island’s early settlers and indigenous peoples, who revered the powerful cascade as a source of fresh water and a spiritual site. Over the centuries, the waterfall has become a symbol of Réunion’s rugged beauty and is featured in local folklore, often described as the “gate to the underworld” because of the way the water seems to vanish into the darkness of the gorge.
Why It Matters
Beyond its sheer visual impact, Trou de Fer plays an essential role in the local ecosystem. The mist generated by the plunge nurtures a unique micro‑habitat that supports endemic ferns, orchids, and mosses. Birdwatchers can spot species such as the Réunion harrier and the endemic Réunion olive pigeon perched on the cliffs, taking advantage of the abundant insect life created by the waterfall’s spray.
3. How to Get There
Getting to Salazie
- Fly into Roland Garros Airport (RUN) – the main international gateway to Réunion, located near Saint‑Denis.
- Rent a car – a compact or SUV is ideal. The island’s roads are well‑maintained, but some mountain routes are steep and winding.
- Drive to Salazie – follow the N1 highway south from Saint‑Denis, then take the RN3 east toward the town of Salazie (≈ 45 km, about 1 hour).
From Salazie Village to the Trailhead
- Parking: There is a small public parking area near the “Maison du Volcan” visitor centre.
- Signage: Look for signs pointing to “Sentier du Trou de Fer” (the Trou de Fer trail). The trailhead is marked with a wooden board and a map of the route.
Trail Overview
- Length: Approximately 4 km round‑trip (moderate difficulty).
- Elevation gain: Around 300 m, with some steep sections.
- Time: 2–3 hours depending on pace and photo stops.
Tip: The trail is well‑marked but can be slippery after rain. Wear sturdy hiking boots, bring a walking pole, and carry enough water (the hike is in a humid, tropical climate).
