Tuny refuge via the Vallon des Seigneurs and the Vallon Saint-Clair

This is a beautiful loop with a very steady climb through a picturesque valley, under tunnels of vegetation and magnificent suspended rocks. There are splendid views of the Huveaune valley, Géménos, Aubagne and Marseille. Next, pass by the very welcoming Tuny refuge and descend via the Vallon de Saint Clair, which also offers beautiful landscapes of steep rocks.

Description of the walk

There is a small car park opposite the Prieuré de Saint-Jean de Garguier, at the entrance to the Saint-Clair housing estate (small roundabout).

(S/E) Head east and, facing the gate of villa no. 30, take the small path on the left that runs along the side of the hill, with a beautiful view of the priory and then the Château de Saint-Jean. When you reach the access road to the château, turn right onto the path that quickly leads under a pretty little aqueduct.

(1) Continue straight ahead on the path, which climbs very gradually up the Vallon des Seignors for about 3 km.

(2) Passing under a high-voltage power line, ignore the path to the left and continue up the valley. Throughout this section, the path follows a half-buried penstock. Pass the spring catchment (grate) and continue to the left, unless you want to take the shortcut that climbs up to the right. Further on, the path makes a hairpin bend to the right and climbs up the right side of the mountain until it passes at the foot of a large electricity pylon.

(3) Take the track that climbs quite steeply until you reach a rectangular green fire brigade tank.

(4) Enjoy the view. Take the track that descends southwards and follow it for about 1.5 km. At a hairpin bend, stop at the charming Tuny refuge on the left.

(5) Follow the track to quickly reach a three-way junction with a circular cistern in the centre.

(6) Turn left, then immediately right after the cistern and follow the path down into the Vallon Saint-Clair in the undergrowth. Walk for about 3 km, following the hollow of the valley and ignoring any paths branching off to the right or left.

After a beautiful arrival on a balcony above the valley, the path joins a small road at a bend. Follow this road to the left to return to the starting point (S/E).

Worth a visit

In the Vallon des Seignors, you will pass several old circular structures on the right side of the trail: wells, shelters, ice houses, etc

(5) At the Tuny refuge, continue along the path that climbs to the left and you will soon come to a small cave (torch required).

A very good route, fairly easy to follow, with lovely views of the ridge. The climb up to the electricity pylon is steep and, above all, very overgrown with thorny bushes; long sleeves are essential and, above all, no shorts. The Petit Tuny refuge is a cool haven with picnic tables,

A very shaded route, which is pleasant in hot weather but rather monotonous in cold weather. The best views only come into view towards the end of the outward leg.

A gentle hike, the elevation gain is no problem at all. The climb takes place in a very pretty valley with rocky outcrops, traces of life from days gone by. The spring flows well after a day of rain.

At first, the trail follows a path that is more "complicated" than necessary. A quasi-road (wide path) joins the castle after a few hundred metres.

Leaving the Tuny refuge, the path begins with a section of "exuberant" vegetation: brambles, vines... (depending on the season?)
We preferred the forest road (on the right), which also leads to the starting point and offers a beautiful view of Marseille. However, this option is very sunny. Not recommended in hot weather.

A beautiful hike offering sweeping views of Marseille from the summit. The route is easy going, although there is a steep section towards the end of the climb. Not very busy despite its proximity to the city.
Most of the route is unshaded.

A very pretty hike with magnificent views of the surrounding mountains and the cliffs of the hills.
Be careful, there are some steep and rocky slopes. Don't miss the Petit Tuny cave, 200 metres from the refuge.

A beautiful walk with no major difficulties.
There are numerous points of interest along the route and an incredible panoramic view at the highest point.
The climb is on a single-track trail, which is also used by mountain bikes (going downhill), so keep an eye out for oncoming traffic.
For the cave, go to the end of the meadow, where the cliff is slightly to the right behind the trees. The cave is well worth a visit.

Easy parking during the week next to the priory. Be especially careful when starting off, facing the gate of villa no. 30
on the left just behind the gate, a small path quickly joins the trail. A pleasant hike with no difficulty, with two sections on a DCFI road. On the descent to the cistern, turn left and then immediately right as indicated onto a pretty trail

very beautiful hike on the peaks, beautiful view of Marseille, small path in the valley, be careful, it climbs and climbs and climbs. Turn left after the small improvised fountain, arrive at the first cistern, take the track on the right to reach the refuge, take a short lunch break at the tables and chairs, small meadow for a rest in the shade under the trees, then return to the car park

The route is very well described. I had done the reconnaissance by going down through the St Clair valley, but I preferred to do the hike via the track to the right of the valley. It offers many more views of Marseille and the sea. And it allows you to climb up to the St Clair chapel: a very pleasant detour

A very pleasant route, sheltered from the wind and, best of all, you can picnic inside the Tuny refuge. However, although there are few or no people on the Vallon des Seigneurs, the refuge is well known to locals.
No particular difficulties.

Hello,
is the Tuny refuge open all year round? Can the door to the refuge be locked? If I have a mattress and a warm sleeping bag, is it possible to spend the night there?
Finally, do you know if there are any patous (mountain dogs) on this route at this time of year (December 2023/January 2024)?
Thank you very much
