Description of the walk

To get to the starting point:
From Iffendic: take the D61 towards Plélan-le-Grand. After about 3.7 km, in a wood, take a road on the right. A sign indicates the right direction for the Chambre au Loup.
From the Lorient-Rennes expressway: take the Plélan-le-Grand exit, then follow signs for Plélan-le-Grand. At the first roundabout, go straight ahead, then take the second right onto the D61 towards Iffendic. In Saint-Péran, stay on the D61 towards Iffendic, taking the small road to the left. After about 5.3 km, you will see the road to the Chambre au Loup with a sign on the left.

Take this small road for 1 km until you reach the car park, which is signposted on the left. To reach the start of the walk, take the path on the left, perpendicular to the road. At the entrance to the woods, you will find an information board about our walk.

Yellow markings and sign for "La Chambre au Loup".

(S/E) From the car park, take the path next to the sign that enters the woods. After 100 m, turn left and follow the path to the road (D61). Please note that this road is very busy!
Follow the road to the left for 30 metres and take a path that enters the woods on the other side of the road.
200 metres after a signpost, the path turns left and crosses a crossroads. Ignore the small paths on the right and left and continue for about 270 metres.

(1) Find a path that branches off to the right and turns back at an angle of about 150°. Follow this path until you reach a road.
Continue on the path opposite, which crosses a wood and then turns right, following the fields until you reach another road. Follow this road to the right, then take a 90° right turn and turn left onto the path that leads to the Route de Boutavent. Be careful, the main road is very busy!

(2) At the crossroads, take the small road slightly to the left towards Boutavent. At the end of the road, continue straight ahead until you reach Boutavent Castle, a large clearing with information panels, benches, etc.

(3) To continue the circuit, walk along the site on your right and follow the path under the trees. Continue until you reach a field, then take the path on the left which leads to a road.
Follow the road ahead, cross the Touche crossroads, pass the beautiful farmhouse on your right and continue along the farm track.

(4) After a sharp left turn down a valley, the path enters a long right turn. In this turn, find a small path that branches off to the left. A sign indicates that you are entering the Vallon de la Chambre au Loup site. Continue along the path until you reach a crossroads.

(5) Possible alternative: see § Practical information.
Turn left, walk along the rocks, then descend into a valley, cross a stream and immediately climb up the other side. Once at the top of the rocks, another descent awaits you. Cross the stream at the bridge that follows and turn right.

(6) The trail climbs up the hillside and follows the valley until you reach a path that descends to the right. Before the house, climb the rocks on the left and continue uphill. Finally, the trail descends again and you arrive at a bridge upstream from the Étang de la Chambre au Loup.

(7) Cross the bridge and follow the pond on your left until you reach the dam.

(8) Climb the fairly steep hill to the right of the dam until you reach the top.

(9) Enjoy the view one last time. Turn right for a few metres, then head into the woods on a path that branches off to the left. Continue until you reach a T-junction. Turn left and you will reach the car park after 200 metres (S/E).

Notes

Between (5) and (7) there are some very steep climbs and descents. There are also some exposed rocky sections.

Between (8) and (9) there is a difficult climb.

For those who are not very agile, take the alternative routes instead. For these sections, wear good hiking boots.

(5) Alternative route for those who are not very sure-footed and unable to tackle very steep ascents and descents. They can return to the car by turning right and following the white markings.
I have not yet been there and cannot describe this alternative route. Parents with young children should also be vigilant.

(8) Alternative route: if you don't want to take the path, which has a very steep climb, you can cross the dam and descend to the right to reach the road below.
Follow the road to the right to reach the car park.

My hike includes sections of the trail in reverse from the hike " From La Chambre au Loup to Château de Boutavent in Brocéliande " described by Bobthenew.
The one described here is in reverse, is shorter and follows the signposts closely, which makes it easier to find your way, especially around the Étang de Trémelin with its many paths and at the site of the Chambre du Loup. Unlike the other hike, it does not include the Étang de Trémelin.

Enjoy your hike!

Worth a visit

(3) The Château de Boutavent is worth a visit.

Between (5) and (7) Rocks and moors with colourful flora and breathtaking views.

(9) Very beautiful panorama.

Nearby:

(1) The Trémelin Lake with its water sports centre. There is a path around the lake.

very pleasant route... the last 2 km are quite hilly... yellow markings... be careful at one point where there are two yellow markings pointing in different directions... take the "chambre aux loups" (wolf's room)... during the week it's really quiet, relaxing... and beautiful

Hello. We did this route yesterday (very wet after the rain, but never mind). There was a bit of confusion at the small bridge when we arrived at the pond. The instructions at no. 7 in the description are too brief. I would add: Cross the small bridge and turn right. Follow the pond on the left bank, following the GR signposts.
On the map, the numbered points hide the paths in the valley. If technically possible, they should be moved slightly and the "legs" of the numbers should be stretched.
Otherwise, the description is well done. Thank you for this beautiful route!

hello,
very beautiful route, but I think it would be better to start at the end, which is very difficult – we got lost and were rescued by a passer-by!!! And the whole route through the woods is a bit monotonous
there are still some gaps in the explanations: it took us a while to find the small path that leads to the site of
Boutavent, it's not easy to find at all, especially as the road signs are very few and far between!!!!!!
otherwise, it was great, we're planning the next adventure, but it does us good...

superb scenery, best enjoyed in dry weather as there are rocky and slightly steep areas

Enjoy your hike!
There aren't many people (a few more at the dam, but after that you won't see anyone), and it starts off calm and very flat in the forest before you come across the ruins of Boutavent Castle, which is quite interesting.
After the castle, the landscape changes to valleys, red rocks and rivers... A real treat for the eyes!
In short, beautiful scenery and no need to be a great hiker, as the trail is fairly easy.
Thanks for the route, Pierre56!

We did the hike in the opposite direction to the suggested route, starting from Boutavent, so we began by crossing the Putenoë woods (a flat, shaded and beautiful forest trail) before arriving at the more technical (steep climb and/or descent over rocks) and busier section known as "la chambre au loup" (the wolf's den) you need to be well-shod, but the effort is really rewarded by the magnificent panorama. The return trip along the stream is peaceful and without any particular difficulty.
The hike is well signposted (follow the blue arrows).
The landscape is varied and there are almost no paved roads

I don't think I'm very good at understanding directions, so I often get lost, but the map and route are very clear, so I can find my way around with those, and when I'm really lost, I compare with Google Maps to find my way back. But it's true that the written explanations are often confusing for me in some places. Otherwise, it's a great website with lots of beautiful walks to download. Thank you, I'm really enjoying it!

In fact, I combined two trails starting from St Gonlay: the mill trail to the north and the Orinou trail to the south.
At La Vallée, I took the Chambre aux Loups trail to return via the Landier des Bruyères, the Gargantel rocks and back to St Gonlay. A 20 km trail.

Very nice, I did this route clockwise, pretty forest with little elevation gain, after the medieval site, in the moorland there is a narrow, winding path with a few descents and ascents, passing through the rocks. Beautiful panoramic views, the approach and along the pond are picture postcard images. Thank you for this hike.
