The Trou de Fer is a deep, sheer-walled canyon cut into the Bélouve forest plateau, with several waterfalls dropping into it from multiple directions at once. The viewpoint reached from RD48 above Grand Îlet gives a distant look down into the gorge, though the full scale is easier to appreciate from the air or from further along the Bélouve forest trail. Cloud frequently drifts through the gorge, which can obscure the view for stretches at a time.
The Trou de Fer, or Iron Hole, is a deep, sheer-walled canyon cut into the Bélouve forest plateau in the Salazie area of north-east Réunion, a French island in the Indian Ocean. Several waterfalls drop into it from multiple directions at once, forming one of the island's most dramatic natural landscapes. The viewpoint reached from the RD48 above Grand Îlet gives a distant look down into the gorge, signed along the road, and is the simplest way to see it. The full scale of the canyon is easier to appreciate from the air, on helicopter flights, or from further along the Bélouve forest trail, which leads to closer vantage points. Visitors typically spend 30 to 60 minutes at the road viewpoint, taking in the waterfalls cascading from different rock faces at the same time. Those who want a deeper experience can hike a descent route that takes around six hours. Cloud frequently drifts through the gorge and can obscure the view for stretches at a time, so patience is rewarded, and checking the sky before setting out is wise. Mornings before cloud fills the gorge give the best odds of an unobstructed view, and May to October is the drier period. The best photo angle is from the viewpoint railing when cloud thins and sunlight lights the waterfalls. The viewpoint is busiest in the dry season and on weekends, and quieter on weekday mornings. No public bus serves the viewpoint, so visitors drive the RD48 towards Grand Îlet from Salazie. The nearby Bélouve forest and gîte are a natural extension of the visit. Warm layers and rain protection are sensible because the area sits at altitude and weather can change within minutes. Trail users should keep to marked paths, since the gorge edges are steep and unfenced in places.
