To make up for the frustration of not being able to do the Martel white trail because the shuttle was full, this is a good compromise.
I continued a little past Trescaire, but as the views were less spectacular, I turned back. A total of 6.2 km in 1 hour 45 minutes.
It was impressive to walk alongside the tunnels in the dark, but it was quite an experience

For parking, follow the Samson corridor 1.3 km below Le Point Sublime.
This route is part of the Blanc-Martel trail, which ends at the Maline chalet... 14 km further on

A nice walk if you're not sure you can do the whole Blanc-Martel route.
Don't forget your torch, as the second tunnel is quite long.
And what a view!
Can be combined with a refreshing break at Pont de Tusset (15 minutes from the Samson corridor car park)

A nice, refreshing and original little walk for my three teenagers. Parking is mandatory (€7) because the police were there at 9 a.m. this morning...

When it's busy, arrive early to park in the small car park, or budget for parking fines if you park on the road. A nice walk if you're not sure you can do the whole Blanc-Martel route.

Hike starting from the sublime point. First, a descent along a beautiful trail with stunning views that joins the access road to the Samson corridor. Stairs and paths lead to the first 650-metre corridor. A torch is essential as it is completely dark after a few metres. We brought our water shoes to comfortably cross the numerous pools of water in the tunnels. Then we quickly reached the viewpoint. We spotted a couple of vultures. Beautiful views of the Verdon. Then we climbed back up to the sublime point.

At this time of year, the route was not very busy. It was a pleasant and easy walk, which we extended by taking part of the Blanc Martel trail. We were able to admire the vultures.

Departure from the sublime point. A short but sufficient hike in hot weather, which was the case that day. Fortunately, the tunnels cooled the atmosphere. Don't forget a headlamp to avoid stumbling around in the dark. Best done early in the morning to avoid the sun.

A great, unusual and fairly short hike (it took us about 1 hour 45 minutes there and back).
A torch is essential for the tunnels, which are very damp and require you to wade through water.
In high season, it must be quite busy because it's very cool.
It was great and we really enjoyed it, thank you!

A very beautiful hike starting from Point Sublime, which took us to the stairs at Brèche Imbert. We completed the round trip in 5 hours and 50 minutes.
The trail is very well maintained, the views are magnificent, and the vegetation is very green at this time of year (late May).
As it was quiet at this time of year, we were able to enjoy the walk to the full.
NB: you can park at the Samson viewpoint car park instead of Point Sublime, which I admit saves you an extra 30 minutes of climbing on the way back...

2 possible starting points
either from the sublime point with a superb descent but tough to climb back up
or from the cul-de-sac road, but parking along the road is very congested in the parish specific to Brittany

yes, it takes 30 minutes
but you have to go further, it's not worth it to do just that or do the entire Martel trail or do as described. On the way back, we sit by the water. Thank you, it's still lovely...
