A lovely hike of moderate difficulty, indeed. Beautiful views of Sainte Victoire. The GPS track isn’t quite accurate; it must have been put together rather hastily!

The trail is not suitable for all hikers.
It can be difficult to find your way, and there are some challenging sections (steep climbs and sections along the side of a hill right next to a precipice). However, the landscapes are very varied and pleasant, even in autumn
You have to look for cairns to find your way

The route is very varied, but requires careful attention to follow the trail until you reach Lake Bimont. We had some difficulty finding a few paths. But that's also part of the charm of this hike.

Route difficult to follow on the map. No markings on certain sections.
Pleasant hike, especially along the Cause. Lovely views of the two dams. A few slightly steep sections.

An interesting route that follows the course of the Cause ("wild") river before the Zola dam and a little beyond. You even have to cross it on a small wooden bridge before tackling the steep climb to reach the Bimont dam. Thank you for this beautiful route.

To reach point 2, follow the dotted line marked 'la petite mer' on the map, as the GPS track is too steep to descend directly to the bottom of the stream. Then, enjoy 2 to 3 magnificent views along the banks of the Cause stream (fish visible). After point 5 at the end of the Zola lake trail, which is a circular detour, go straight on at the crossroads with the yellow sign to continue following the Cause. Between points 6 and 7, there is a very steep climb on rocks, which is challenging for 76-year-olds, but it is manageable. Then there is a walk with lots of people, especially on a Saturday. Otherwise, it is ideal for seeing the two dams. Use GPS continuously in addition to the somewhat brief description

We never found the second sign. Once there, the red markings were incomprehensible, and sometimes non-existent. We relied on the map and signs, but the route is not the one indicated here, nor is it of the same difficulty (more complex passages for the inexperienced).

A very pleasant trail, especially the first part (but that has already been mentioned). With a little experience and an IGN map, you don't need a GPS. The trail is not very busy, except near the Bimont dam and Le Tholonet.
Thank you to those who go to such lengths to give us pleasure!

Hello,
The route was good, but at one point we had to change course when we were supposed to head north-east because there was a barrier with a sign saying 'no entry due to risk of rockfalls and falling branches'. We could see from the tracks on the ground that people were going around the barrier, but we decided to play it safe and changed our route so we could come back later. Otherwise, it was a lovely walk and we had a great day. Thank you, Visorando.

Hike completed on 2 November 2022. I couldn't find the path at point 2. I had to turn back and rejoin the GR to reach point 3. Same problem at point 6, where I couldn't find the path to cross the Cause. I turned back and managed to cross at another point and rejoin another path. In total, we walked almost 12 km. The route is very pleasant up to the Bimont dam (although you have to keep your eyes glued to the GPS), then the second part is much more classic. We hardly saw anyone until we reached the Bimont dam. Be careful with the orientation difficulties. It's easy to get lost on the small paths, especially as there are many places in the first part where there is no internet connection (and therefore no GPS...).

A magnificent hike, especially today when the morning sun pierced through patches of fog, it was like being in a traditional Chinese painting! The entire beginning of the route was new to us, although we were familiar with the trails around the dams; even the end between the aqueduct and WP10 was new. So thank you for introducing us to these trails.
There weren't too many problems following the trail, but you do have to pay attention: between WP1 and WP2, don't miss the trail on the right, and just before the WP6 branch bridge, you have to feel your way a little.
We came across a few couples, but ultimately there weren't many people compared to what we usually see or on weekends.
