The Cross and Castrum of Saint-Marcel

A very pleasant walk that first takes us to the Croix de Saint-Marcel, where there is a superb view over the Huveaune valley as far as Sainte-Baume to the east and the bay of Marseille to the west. It continues along a little-used path towards the old castrum of Saint-Marcel.

Please note: read the reviews carefully before setting out on this hike. The section between (6) and (7) is very ‘wild’, and at several points the path disappears completely.

You are in the Calanques National Park, which is subject to specific regulations. Failure to comply with these regulations may result in a fine of up to €1,500.

Description of the walk

Park in front of the Camille Julian Vocational School.

(S/E) Take Rue du Val Chaumery, cross the Canal de Marseille and, about a hundred metres further on, turn right. Follow the yellow and red markings ofthe GR®®2013and the blue markings along a wide track heading west.

(1) After passing under a high-voltage power line, turn left at the crossroads. Follow the track for about 250 m and turn onto the path on the left which climbs gently to the Croix de Saint-Marcel, passing under high-voltage power lines twice.

(2) Enjoy the view from the cross and continue along the path.

(3) At the junction, turn left. Continue straight on to Col Galvaudan, then follow the track to the left, heading south-east, for about 50 m. At the cairn at the edge of the track, turn right onto a path that quickly splits in two: left (south) to reach the source of the rushing waters and right (west-south-west) towards Mont Saint-Cyr.

(4) Turn right and follow the path leading to the watchtower. The remains of this old watchtower are barely visible, but a sign reading “La Vigie 492 m” is painted on a flat rock. On the right-hand side of the path, you can still make out an arrow pointing towards Saint-Marcel and another towards Mont Saint-Cyr. To the left, a path leads to the Source des Eaux Vives.

Follow the path to the right (north-west); it is barely marked at first but becomes quite easy to follow.
You’ll find (not often enough) old brown markings. As the path isn’t used much, the vegetation tends to take over, but you can’t miss it!

(6) The path heads north after passing a small rocky outcrop (very easy if you spot the brown markings). A little further on, you’ll come across the two high-voltage power lines. After the pylons, the path descends towards a house. At this point, you’re right in the thicket, but you’ll be out of it very quickly. Leave the house on your right and follow the path that goes round the rocky outcrop.

(7) Just a little more effort to climb up to the ruins of the old castrum. From the top, you can still enjoy a beautiful view of the valley. Turn back.

(7) Turn left onto a path that is barely visible from above but very pleasant under the canopy of trees. This path descends to Boulevard de la Forbine. Follow this boulevard to the right for 20 metres, then turn left into Parc de la Forbine.

(8) Keep to the left, follow the path and return to the junction at the high-voltage power line.

(1) Turn left, then veer left again about fifty metres further on to avoid taking the same path as on the way there. Walk down under the high-voltage power line and head towards the Canal de Marseille. Turn right to walk alongside it at a distance.

(9) Turn left to get even closer to the canal and follow it to reach Rue du Val Chaumery.
Follow this street to the left to return to the starting car park in front of the vocational college (S/E).

As mentioned in several comments: between points 6 and 7, it’s very ‘wild’, and at several points you can’t see the path at all. You really do need long trousers, as you have to make your way through the vegetation as best you can, including thorny bushes.
We wondered several times whether we should turn back, but as we had the route map with us, we knew it wouldn’t be that long… in terms of distance. But in terms of time, this section took up about half of our total hike (3 hours in total).
For your information, when you reach point 7, at the old Castrum, you’ll come face to face with a chain and a red sign reading ‘DANGER ACCES INTERDIT – NO TRESPASSING’.
I would recommend looking into an alternative route to avoid the section from 6 to 7 on the current route.

In my opinion, this route is quite difficult. From point 5 onwards, it’s practically impassable, if not downright dangerous.
You’ll need thick trousers, as the thistles are merciless!
It’s a shame the path hasn’t been cleared
Otherwise, the views are well worth a look.

Up to point 5, it’s a lovely walk! After that, it becomes very difficult to make headway… The path hasn’t been used for a long time and hasn’t been cleared, so you’d be well advised to wear fairly thick trousers! At times, I struggled to find the path, which was completely overgrown. I was alone with my dog; thank goodness nothing happened to me as I was truly all alone in the world! Perhaps this hike should be classified as ‘difficult’ rather than ‘moderate’!
And unfortunately, the castrum was marked as off-limits due to danger.
In short, be careful if you decide to do this hike!

PLEASE NOTE.
The walk is lovely. Well described up to stage 5. But between 5 and 7, there are no signposts. The vegetation is so tall that you can’t see where you’re stepping. It’s dangerous and time-consuming. Thank goodness we didn’t have any grandchildren with us. We should have read the reviews more carefully, as several people gave up. You have to turn back at stage 5 or follow a different route. For the first time, we questioned the quality of the app; there is clearly no verification other than the reviews from people who have done the walk before us.

We did this route in the middle of August in the ‘cool of the morning’, i.e. between 6am and 10.30am (Calanques National Park access permitted: green), tackling all the climbs in the shade!
A lovely discovery featuring the Chapel of Nazareth, the Castrum (keep an eye out for the access path), a short detour via the pagoda, the pass and the cross of St Marcel; beautiful views over Marseille and the Huveaune valley, the Côte Bleue, the Garlaban, the Etoile massif, the Pic de Bertagne and, at times, the Auréliens mountains
Bring water and a hat, and wear long trousers (thorny and overgrown vegetation)

A very pleasant walk, especially in the first half. There are stunning panoramic views of the whole of the Marseille metropolitan area throughout the walk. However, from points 5 and 6 onwards, the path is difficult to follow, and the overgrown vegetation makes progress quite difficult due to the dense, thorny undergrowth (long trousers recommended).

I tried this route but had to turn back, as the area around checkpoint 6 had become extremely overgrown.
It’s a shame, as it’s an interesting route.
Cheers.

A lovely walk with several spots offering views of Marseille that are well worth a detour.
Be warned, however, this walk may not be to everyone’s taste...

The route is fairly straightforward, but here is some additional information to supplement that provided by the author, which might be helpful:
- Allow around 2½ hours (including a few short breaks to enjoy the view and have a drink) for this walk if you’re a keen walker,
- From point 4 to point 8, the vegetation is quite dense, and the path isn’t always easy to spot. I recommend wearing trousers and shoes that provide good ankle support, as you can’t always see where you’re stepping (particularly halfway between points 6 and 7).
- The small rocky outcrop mentioned at point 6 can be ‘climbed’ (easily); do not try to go round it. Personally, I had quite a bit of trouble spotting the brown markings, but the path remains visible.
- Just before the second pylon between points 6 and 7, make sure you take the path that goes past the pylon and heads off to the right (another path, which is more difficult to access, branches off to the left to go round the pylon).
- After point 7, the path leads through dense undergrowth. The descent is easy, but you’ll need to make your way through the branches.

In short, a route I recommend if you like to get off the beaten track and don’t mind walking through denser vegetation where the path isn’t always easy to spot!
If not, the walk from the starting point to point 4 is well worth it and is much easier to access. You can return via the same route, and there appear to be several alternative walks to this one that might suit you better.
