Pont-en-Royans: Les Trois Châteaux, Serre Cocu

The Trois Châteaux viewpoint offers a bird's eye view of Pont-en-Royans.
From the Serre-Cocu orientation table, there is a beautiful panorama of the eastern ridges of the Vercors, from Grande Moucherolle to Grand Veymont.
This hike takes place partly in the forest and follows roads to avoid private property.

Description of the walk

Departure from Place de la Halle in Pont-en-Royans.

(S/E) From the square, walk a few metres to the right and turn left onto Rue du Temple. Climb up a marked path through the narrow streets of Vieux Bourg. When you reach Chemin du Bourg, follow it to the left, go through the medieval Sainte-Agnès gate, then turn right about 50 metres further on (sign and markings) onto the path that climbs up the mountainside.

(1) At the first intersection, turn right, going back and forth, heading south-east, on the path up to the viewpoint and the Trois Châteaux orientation table.

(2) Return to the previous intersection.

(1): On your return, turn right, heading north towards Col de Toutes Aures. Stay on this well-marked path and continue north. Further on, the path makes a 90° turn to the right. Continue south-east, ignoring the next fork (difference between thePR®® route on the IGN map and the change in the path on the ground). The path descends slightly, then after another 90° turn to the left, climbs northwards.

(3) At the three-way junction, follow the path on the left, climbing up to the Campeloup road. Follow it to the right and reach the Col de Toutes Aures.

(4) At the intersection at the pass, you will find yourself facing three roads. Follow the middle one, the D292, towards Les Champs, which continues straight ahead, despite the signpost.

(5) Walk past the Champs farm, leave the D292 and follow the small road on the left that climbs towards the Arnaux stopover lodge. Just before the lodge and before the hairpin bend, take the path on the left at the bottom of the car park, heading south-west. At a bend, the marked path turns right, heading north, and joins an intersection.

(6) Turn right heading north-east onto the Serre Cocu path, walk past a beautiful farm on your right, continue and reach the Rintanpan crossroads (mast). Then take the well-marked path on the left, which climbs to the top of Serre Cocu.

(8) Return to the previous intersection.

(6) Turn right, heading south-west, onto a path that continues for almost 2 km and crosses a track. Stay on this well-marked path, ignoring the various tracks that branch off. You will cross to the other side of the valley. Continue to the road and follow it to the right until you reach the Mûrier mast.

(8) Take the small path on the left, heading south, and join the road, turning 90° to the left. Follow this small road to the old Belière farm, where the road gives way to a well-marked path that descends to a stream, which you will cross by fording. Climb up opposite and continue to the hamlet of Courtevoux. Join and follow the Chemin du Réservoir, skirting the Paradis neighbourhood. Take the Chemin du Bourg.

(9) Reach the old village. From there, all paths lead back to Pont-en-Royans, allowing you to visit this old medieval village at your leisure (S/E).

Please note: there is a difference between the IGN route on the map and the route that avoids passing near the Campeloup farm, just before point (4).

Worth a visit

Pont-en-Royans is a village steeped in history. The Dauphiné archives reveal that there were three castles: the first castle in the old topographical name corresponds to the fortified village. The second castle is the current ruin above the "three castles mountain". The third castle, dating from the 17th and 18th centuries, was destroyed during a bombing raid in 1945 and corresponds to the location of the college. Its ramparts, of which only a few remains are left, include "La Porte de France", "La Porte Agnès", "La Porte de Villeneuve" and "La Porte du Merle".

The village and its houses clinging to the rock face.

Water museum and landscaped banks of the Bourne.

Easy parking: just drive through the village, cross the bridge over the Bourne and turn right: there is a large car park about a hundred metres further on, downhill on the right. You can reach the village directly via an area designed for walking and picnics along the river: from here, there is a magnificent view of the village and the houses suspended above it. On the way down, you can avoid a stretch of road by taking a path that branches off to the left to avoid Le Murier. However, this hike does involve quite a few tarmac roads.

Superb hike with magnificent views.
Despite the elevation gain, this hike is easy to do because the trails are relatively straightforward.
We made the following changes, which I recommend
- Given the lack of parking in Pont-en-Royans, we started from the cemetery (large, easily accessible car park) and went up Rue du 19 Mars 1962.
- To avoid too much tarmac, we cut out the second section of the route: on the descent, as soon as you reach the road, after the first bend, there is a path (visible on the IGN map) that goes directly to La Bélrière and cuts across the section towards Le Murier. The start is difficult to find, but the path is superb.
We came back down via the steps of the medieval town, skirted the village via the bridge over the Bourne to see the houses suspended above the river, and returned along the banks of the Bourne to the cemetery car park, completing a superb circular route.

We did a "shortened" version as a family, to make the climb a little less steep: we didn't go up to Serre Cocu, cutting across from Col de Toutes-Aures to Mûrier via Le Faucon. Very nice in spring! Lovely view from the castle and the pass.

A very pleasant hike uphill, in the coolness of the undergrowth, with little road traffic and beautiful scenery on arrival at Serre Cocu.
The descent is long and rocky, which we enjoyed a little less.
We had a lovely day.

A very beautiful hike, but quite difficult. I would advise the author to increase the difficulty level.
On hot days, we recommend setting off very early in the morning (7 a.m.) because the start of the hike is on the shaded side of the mountain, so it is cooler and the climb is less strenuous. What's more, the scenery is magnificent with the yellow colours of the morning sun.

A good part of the hike takes place in the forest, which allows you to walk in the cool. Some people complain that there is a lot of road, but we didn't find that to be the case. The roads used are small mountain roads that are extremely quiet and rather pleasant. In any case, we didn't see any shortcuts to avoid them.

In any case, the route is very pretty and the views are magnificent. We extended the hike to the white waterfall via the Bernissard path because it's worth the detour, and it's a great way to cool your feet! In the end, it took us about 5 hours and 20 minutes without breaks.
I'm not giving an opinion on the author's description because I never read them lol.

Hello,

I am reposting information from previous messages in this conversation and messages read on the "visorandonneurs" Facebook page.
Shouldn't the difficulty level be revised upwards?
When I enter the route, I get a score of 101 on the FFR website, which is quite difficult, probably due to the elevation gain

Have a good day!

A beautiful hike, with a bit of road between Toutes Aures and Les Arnaud, but with very little traffic. We made a mistake along the way before reaching Toutes Aures: instead of going back up to Campeloup, we followed the marked path that took us through Bonne Perdrix (a minor detour with no consequences).
Beautiful view of the Vercors mountain range from Serre Cocu. Thank you!!!

Thank you, Lilian Blachon
But does the presence of tarmac (which some hikers like) call into question the quality of the description or the map?

A very pleasant route for this outing starting from Pont-en-Royans, which I completed by running.

It should be noted that the "authorised" route to Col de Toutes Aures (just before Point 3) has been slightly modified so that it no longer crosses private land. You now have to go down the path and then back up to the pass. It's not a very big detour, but it avoids an encounter with the landowner, who doesn't want hikers on his property. The route is well marked on this section.

The box tree moths mentioned in other comments are no longer a major nuisance in the area this year (2018), whereas they had been a terrible problem for several years.

The viewpoint with the sign at Serre Cocu is a good spot for a picnic.
