Îlet des Orangers via the canal

One way to access the Cirque de Mafate is from Sans Souci. The pipeline path may seem long, but the landscape overlooking the Rivière des Galets from a height of 500 m is breathtaking. From above, you can see Deux Bras and the narrow gorge through which the Rivière des Galets flows out of the Cirque de Mafate.
The canal path has a gentle slope. After the water catchment, access to Îlet des Orangers is via a narrow gorge after a steep climb.
Estimated elevation gain: approximately 700 metres.

Description of the walk

To get to Sans Souci, take the Chemin des Orangers road and park near the "Citerne Rouge" bus stop. It is also possible to take the bus to the start of the hike.

(S/E) Near the bus stop, a gravel road with concrete bends climbs steeply. You can climb directly by cutting across the switchbacks, following the large yellow markers that indicate the underground pipeline.
After climbing for about 500 metres, you will reach a large cistern, which you should go around on the left.
The path becomes a wide dirt track that now climbs into the Sans Souci Forest in increasingly tight hairpin bends.

(1) About 1.5 km after the cistern, a signpost indicates the start of the pipeline path on the left.
The path now clings to the cliff with a view of the pebble river 500 m below.

(2) After about an hour's walk, you will reach a spot where the path has collapsed. Walk along the pipeline, holding onto a handrail.
Immediately afterwards, cross a passage that may be wet and very slippery if it has rained. Water falls from the cliff onto your head.

(3) After walking for about another hour, the path passes under a tunnel and continues along the cliffside. There is another beautiful view overlooking Bras d'Oussy and the footbridge that leads to Cayenne.

(4) About 4 km after the tunnel, you will reach a fork in the path leading left to Îlet des Lataniers. Continue straight ahead to reach the water intake.

(5) Shortly afterwards, at the Orangers water intake and its basin, the path changes completely. After going around the basin on the right, cross the stream via a small ford. The path quickly climbs up stone steps, crossing the stream several times, all within a very narrow gorge. Then follow the path as it continues to climb.

After about 50 minutes of climbing, you will reach the sign marking the entrance to Îlet des Orangers. Turn left to reach the school, chapel and dispensary square.

(6) There are two picnic tables in the schoolyard. A drinking water tap is attached to a large rock behind the school.

After enjoying the area, return to Sans Souci via the same route (S/E).

Notes

(4) You can make a round trip to Îlet des Lataniers by going down to the left. Allow 30 minutes to go down and about an hour to come back.

The route has been surveyed on the ground. It is unlikely that you will get lost on the pipeline path. On the way up, there is a rampart on the right and a drop on the left...
The total elevation gain is greatly overestimated. The path is narrow and clings to the side of the rampart. A small error in the GPS or map adds +/-10m to the cumulative elevation gain. I estimate the elevation gain to be 700m.

The canal path is quite narrow, about 2 metres, but the feeling of emptiness is sometimes mitigated by the vegetation on the side of the void. However, due to 3 or 4 passages, this hike is not recommended for people who are prone to vertigo.

You can reach the start of the hike by bus from Saint Paul (line 8.5), getting off at the Citerne Rouge stop.

It can be hot, so bring water with you. Of course, swimming is prohibited in the catchment basins...

There is a water tap attached to a large rock behind the school at Îlet des Orangers.

There are two picnic tables on the school grounds at Îlet des Orangers.

Worth a visit

The Chemin de la Canalisation des Orangers is a path that was built to lay a pipe that carries drinking water from the catchment area to part of the commune of Saint-Paul. The pipe is visible on the side of the path, but is sometimes buried.
Work on the path to build the pipeline began in 1965 and lasted 10 years. Seeing this path and this pipeline, one cannot help but think of the workers and engineers who built this path, transported the pieces of the pipeline and welded them together on site. With what means?
Instead of making a round trip in a single day, over several days, you can make a circular loop via Îlet des Lataniers and Cayenne, or continue on to Roche Plate or exit via Maîdo.

We have planned the hike for July 2026.
The download is for preparing our holiday.
I find the route description and maps very informative and valuable.

Thank you!

Apart from the first 2 km, the rest is flat, but with magnificent views all along the route. We turned off towards Ilet des Latanier instead of Ilet des Orangiers, with magnificent views and a very easy river crossing

Superb hike! A bit difficult at the beginning to reach the canal path, and at the end to reach the Îlet des Orangés, but everything else is flat! At this time of year, there was plenty of shade, so I didn't suffer from the heat. There are several streams where you can cool off. There are a few muddy areas to cross, but they are completely passable. I didn't meet many people, barely 10.
It was a beautiful, long day's walk. It took me 9 hours, including breaks, which were necessary to admire the breathtaking views...
Not for those who suffer from vertigo. The path is wide, but the slope is very steep!

We did this route in one-way and return, but another idea would be to spend a night on L'Ilet des Latanier (below L'Ilet des Orangers) and return via "the lower route". Someone suggested this to us afterwards, and I think it's a good idea, but you either have to walk further (though it's probably doable in two days) or hire a 4x4 to take you back to your car, apparently!
I think the person who posted the hike slept at Ilet des Orangers, as it says 7:55 p.m. LOL.
I recorded my route on Visorando because I was following the GPX and it recorded 10 hours and 10 minutes, including 7 hours of actual walking.
We took shortcuts on the way there to give our cardio a boost LOL, but not on the way back because, frankly, after so many kilometres, we preferred to give our knees and feet a rest.
Note: in the morning, be sure to bring sun protection +++. On the way back, you're completely in the shade.
Our car was not damaged while we were away.
I agree with Danielfr40 = the hike is worth it more for the route than for the destination, which is ultimately a good thing given the length of the route
Remember to look down as you approach the islet of Lataniers: there is a magnificent waterfall...:

The duration and elevation gain of the hike are incorrect. We are average hikers and it took us 5 hours to reach Îlet des Orangers with an elevation gain of approximately +600m and -90m (the terrain distorts the GPS data). The return trip may be a little faster. At the starting point, it is advisable to take every shortcut without hesitation, as they all lead back to the trail. The first is 20 metres above and after the red cistern. Climb this trail until you reach the signpost indicating the direction of the islet. The pipeline trail is about 1.50m to 2m wide and safe. The views are magnificent. This is certainly the easiest way to reach the islet when coming up from Mafate below. It is true that it is best not to leave your car at the starting point, as unfortunately damage has been reported on the return journey.

Great hike, diving into the heart of Mafate. The trail along the canal is very easy. Only the last climb, from the retention basin to the orange grove, is really difficult. It's a steep climb! Be careful when you get there, it's cool! However, the time given in the description is not correct. It takes 4½ hours from Sans Souci to the Îlet des Orangers, or 9 hours there and back, and not 19 hours as it says 😅
On the other hand, it's a very popular hike, so it's best to use the toilet before you set off as it's impossible to leave the path for most of the hike... it's not easy to take a toilet break!

The first quarter is very muddy at this time of year, making the track slippery, so it's best to avoid shortcuts
in the cleared areas, as this makes for a wide, almost lane-like path, which is safer.
If the trail is not cleared, it is narrow, with tall grass on either side covering the path, making it difficult to see where you are putting your feet.
Ultimately, apart from the distance and the steep sections, the trail is not difficult
There are superb views all along the way, which is just as well because the Ilet des Orangers offers few views, confirming the adage that it's the journey that counts, not the destination.
It's still worth the climb, and crossing the stream is fun.
Thank you for this route.
