Le Trou de Fer via the École Normale trail

Trou de Fer is an iconic location on Reunion Island. Countless waterfalls plunge into this immense and impressive cavity. Located in the east of Reunion, it is one of the rainiest places on the island!
It is accessible from Bras-Panon and from the Bélouve Forest. From this dense forest, there are three possible access routes: via the Trou de Fer trail, the Allée Cavalière or the École Normale trail.

Description of the walk

Access from Saint-Benoit
Head towards Plaine-des-Palmistes and then Petite-Plaine. On leaving the village of Petite-Plaine, turn right onto Route Forestière 2 de Bébour-Bélouve towards the Bébour forest. Pass the Col de Bélouve (7 kilometres after the Bébour forest). Continue on the same road until you see the sign for the École Normale trail on the right-hand side of the road.

Access from Bourg-Murat
Continue towards Plaine des Palmistes. Pass Col de Bellevue. 5 kilometres after the pass, at the first crossroads, turn left onto the D55 towards Petite-Plaine. Take the first road on the left (Route Forestière 2 de Bébour-Bélouve) towards the Bébour Forest. Pass the Col de Bélouve (7 kilometres after the Bébour Forest). Continue on the same road until you see the sign for the start of the École Normale trail on the right-hand side of the road.

(S/E) Pass the sign and the barrier, then continue on the concrete road for 200 metres.

(1) Turn right onto the École Normale trail. A hundred metres further on, the trail crosses the Ravine Mazerin and heads towards the Plateau Citrons. Most of the time, the trail runs along a wooden walkway. When the trail runs along the ground, it is extremely muddy and slippery! Forty minutes after the start, the trail leads to a forest track, which you will need to follow for about a hundred metres.

(2) At the first intersection, turn right onto Forest Track 27 des Mares.

(3) Turn right again a few metres further on, towards the Grande Mare.
The most difficult part begins here and continues to the Grande Mare.

(4) At the next intersection, leave the path that goes around the pond on your right and continue straight ahead.

(5) A few metres further on, leave the path on the right and take the one on the left.
From this point, the path is paved and crosses the Plateau Cochons.

(6) Leave the path leading to Bras-Panon (difficult path) on your right and continue straight ahead.

(7) A few metres further on, leave the path leading to Allée Cavalière on your left and turn right.

(8) At this intersection, turn right towards the viewpoint.

(9) Go to the viewpoint, where you can enjoy a magnificent panorama of the Trou de Fer, provided you arrive early in the morning! Return to the crossroads by the same route.

(8) Turn left and continue to another junction.

(7) Turn right towards Allée Cavalière. Walk along this pleasant track for 1 hour. Leave the Trou de Fer trail on your right and continue straight ahead on the track.

(10) Visit the Queen of Tamarins. To do so, take the next path on the left of the track. This is a 300-year-old tamarind tree with an enormous trunk! Then return to the crossroads.

(10) Turn left onto Allée Cavalière. At the next intersection, leave the path leading to Lodge de Bélouve on your right and continue straight ahead.

(11) About 100 metres further on, leave the Piste Forestière 27 des Mares on your left and turn right onto Allée Cavalière. Continue to the end of the track, which leads to Route Forestière 2 de Bébour-Bélouve.

(12) Then turn left towards the starting point. Follow the forest road for 1.5 kilometres. Then leave the Piste Forestière de la Vierge on your right and turn left.
Cross Ravine Mazerin again and continue along the same road for 200 metres to the car park (S/E).

The trail given by Visorando is closed. I took it anyway because I didn't have a network connection to download another route when I arrived at the "trail closed" sign. It is closed because it is no longer maintained, but it is still passable despite some difficult sections where the vegetation is very dense and the planks that make up the trail are badly damaged in places. It's a shame because this trail is truly magnificent.
The iron hole is magical! It was my favourite hike because it's so breathtaking!

Hiking made very difficult due to the school's decision to stop maintaining the trail. It is still possible, but vegetation has taken over in many places and the wooden walkways are unfortunately badly damaged along most of the route. It's a shame because the Bélouve forest is extraordinary in this area!

The school path was closed, but we were able to get through. You have to follow the wooden path when you can and walk on the beams as much as possible. Don't do this after it rains. We came back via the bridle path and were disappointed: more people and mud, less attractive and less pretty too.

The Ecole Normale trail is closed. We passed through without any problems. Advantage: no one else on the trail. On the way back, we took the normal trail, which was crowded and muddy.

The L'École Normale trail is closed due to bad weather, according to the forest rangers on patrol.
We took the Cavaliers trail in the opposite direction and after the 9, we followed the sign to the left that indicates Sentier du trou, but on the way back, we took the Visiorando trail, which is not slippery, less walking and less crowded. 3 hours
Thank you for the blue dot, which is a great guide!

The path to the teacher training college is closed. But we met some people who had taken it and had no problems apart from some damage to the path, which slowed them down a little. The spectacle at Trou de Fer is not to be missed... as is a cat waiting for something to nibble on from the walkers.

Hike from the Belouve refuge to enjoy the view of Salazie. We took the Trou de Fer trail all the way as it had just been rebuilt, greeting the Queen of Tamarins (and the ONF staff) along the way. The view was completely clear when we arrived at the lookout point! Between two helicopter flyovers, it felt like we were in a Greystoke landscape... We didn't linger because the trail is closed by prefectural order from August 2021. We returned via the teacher training college trail, where the wooden floor is in very poor condition in places: it is sometimes safer to walk on the sides, especially as the drought (yes, here too, unfortunately...) has left only a few traces of mud. From the Monique hillside to the Belouve lodge (starting point), the Virgin's Path is the most 'natural' part: few wooden floors, river crossings, lush vegetation and magnificent aromas to welcome you on arrival. The detour was really worth it.

Please note that due to rockfalls near the platform, the route is closed by prefectural order.
We still took the Cavalière trail (return from the normal route) to reach the end of the hike.
Do not stay too long on the platform and do not go there in large groups.
The site is magnificent and very impressive. Do not go too late because of the fog from 10 a.m. onwards.
We returned via the Bélouve lodge trail, which is magnificent but a little longer.
At the lodge, enjoy the view of Salazie and Hell Bourg.
This is a walk to do if you don't want to take a helicopter to Trou de Fer.

We set off from HELL BOURG via the Belouve lodge and headed for Trou de FER.
A magnificent, unobstructed view despite the weather forecast.
The BELOUVE lodge plateau is worth a stop for its unobstructed view of HELL BOURG and the SALAZIE cirque.

The climb is quite steep. We used walking sticks.
We are good walkers and took a little less time than indicated on the sign.

At the end of the route, there is a long walk along the road to return to the starting point, but otherwise it is a beautiful hike.

A beautiful hike along the École Normale trail, which takes about 1 hour 15 minutes to complete and 1 hour 30 minutes to return, with wooden walkways and steps along the entire route. Magnificent views upon arrival.

We did this hike starting from the Belouve lodge, which is marked on site as the access point to the Trou de Fer (don't miss the view of the Cirque de Salazie). After a slightly steep descent, we reached the forest track and soon turned right onto the path that joins the bridle path. We didn't see the queen of the tamarins, but perhaps the easy and fast walk made us less attentive. At the next intersection, we turned right to avoid the path in poor condition (marked by a small sign). The walk is easy on the bridle path and you quickly reach the school path that leads to the viewpoint. For the return trip, we made a circular route around the large pond and then rejoined the bridle path, first on the left and then on the right to return to the lodge.We weren't bothered by the mud as almost the entire route is on footbridges or logs. However, along the way, we never saw any signs for the teacher training college path, only for Coteau Monique.
A beautiful walk for everyone in a forest worthy of Jurassic Park. Contrary to what the photos suggest, the view of the waterfall is a little distant (don't forget your binoculars to enjoy it). After the very dense forest, the walk around the pond (very muddy in places) has the merit of opening up the view and transporting us... to the savannah.

We did this hike on 15 December.
The trail is interesting but muddy up to your ankles!
For the less adventurous, it is possible to continue along the forest road.
The trail is less picturesque, as it is paved along the entire length, but your feet will stay dry!
In fact, once you reach the viewpoint, this route is recommended!
Personally, I found the view a little disappointing.

Enjoy your walk, everyone!
