Description of the walk

Depart from the car park (P2) at Lac de Trémelin, located 4 km from the village of Iffendic.

(S/E) Head to the right of the leisure park. Pass the Tourist Office and, just before the sailing school, take the path on the right, which runs alongside the car parks (P1) and then the small access road to the Trémelin site.

(1) When you reach the D61 (caution: busy road), turn left, then immediately right onto the gravel path. After 500 metres, leave thePR® and turn left onto a steeply descending path. Cross the small stream and continue first to the right, then to the left on a gravel path that will soon start to climb.

(2) At the edge of the woods, when you reach a crossroads with several paths, take the one opposite, crossing a grassy area on both sides. After 150 metres, as you re-enter the woods, turn right onto a path leading to the motocross track. Follow this path to its main entrance. Go down the access path to cross a small road and reach the Chambre au Loup car park. Cross it to enter the Chambre au Loup estate (information board at the entrance to the site).

(3) 120 metres after entering the woods, take the path on the right to reach the heights of the Chambre au Loup valley. Continue by taking a small path on the left that joins the main path, still on the heights of the valley, among the pines and gorse. At the first intersection, take the path on the right that descends towards the end of the pond.

(4) Cross the footbridge to climb back up to the heights of the opposite slope, to the second pond known as Ozanne. When you reach the grassy path, turn right near an old house, then immediately left to re-enter the woods.

(5) Cross another footbridge and climb towards the rocks (called Château des Guénâs). 150 metres after crossing another small stream, at the intersection of paths, take the one on the right that climbs and crosses the moors.

(6) When you reach a farm track, follow it to the right. At the hamlet of La Touche, cross a first small road, then 700 metres further on, a second. There, take the path opposite that leads to the Boutavent estate. At the ruins of the Château de Boutavent, head south on the access road to the château car park.

(7) At the car park exit, turn left onto the D61 (caution: busy road) then immediately right onto a small road. After 170 metres, enter the woods via a small path on the left leading to a farm track, which itself leads to a small road. Continue straight ahead to enter the Putenoë woods, first along the edge, then deeper in.

(8) Cross another small road to continue through the woods. After 1.1 km, take the path on the left, which joins theGR®37320 m further on. There, follow theGR® on the right until you reach Lac de Trémelin, then walk along it for 600 m.

(9) Cross the footbridge and immediately turn right onto the path leading to the sailing school, go around the back and cross the car parks. Join the Leisure Park on the right and, after passing the Tourist Office, turn left to return to the car park where you started (S/E).

The departure point should be P1 and not P2, as the start of the route runs alongside P1.
Furthermore, it is not a gravel path but a small tarmac road.

The tracking is fairly accurate, but the unsolicited purchase offers are annoying, especially when you don't have much battery left.

A very pleasant walk with varied landscapes: fields of rapeseed in bloom, moorland, forest, hills overlooking ponds that you walk alongside at times... beautiful views at the Chambre aux Loups...
This is the ideal time of year to do this route, as the trees are not yet in full leaf and the sun shines through, giving us a clearer view. Four hours of walking, a 45-minute break for a picnic, and we are delighted with our day.
We had no problems connecting to the network, and the route was well marked.

A very beautiful, uncrowded hike.
The GPX track may prove useful.
Highly recommended.

A beautiful hike that allows you to discover moorlands that are sometimes undergoing restoration. This work may require changes to the route of the hike.
Apart from these areas, the hike does not present any particular difficulties.
The visit to the Boutavent excavation site is interesting and features numerous information panels on both the excavations and the castle itself. Don't miss the view from the upper courtyard to the north-west of the castle, which overlooks the Boutavent lake and the surrounding countryside. There are many places to take a break, either during the hike or around the lake, which can be walked around in its entirety if you are fit enough.

Thank you.
It is indeed a fairly popular hike, especially now that lockdown restrictions are being lifted.
Have a good evening.

A very beautiful hike; unlike previous reviews, we had no trouble finding our way.
Very pretty scenery, between lake, forest and nature.
The only downside was the crowds; too many people for our liking...

This route could be very nice, but the directions lack precision and the route is very poorly marked, especially at the Chambre pond. We agree with the previous review.
We didn't finish the circular route because the GPS network doesn't work everywhere.
A shame.

Very poorly signposted if you haven't downloaded the app.
I had printed out the route with directions, but I had to download the app halfway through the hike because I got lost several times. Without the app, I don't know where I would have ended up.

Superb walk. Varied landscapes and beautiful views. Route always described in great detail.
We did this walk with two girls aged 8 and 14. They got a bit tired towards the end but thoroughly enjoyed it!
Highly recommended for families, with a picnic in your rucksack!

Hello Chrisetstan,
Thank you for your comment. I hope you enjoyed the hike nonetheless.
The tour of the lake will be combined with another hike, which will be published soon on VisoRando: "Walk between two ponds in Brocéliande". To be continued...

Thank you, chrisetstan, but the description of this hike does not mention any markings (apart from a PR at the very beginning). Therefore, you should not take the markings on the ground into account, but only use the description and the route. Visorando does not mark its routes!

The section from Lac de Trémelin to Chambre au Loup is not particularly interesting.
Following the route, especially around the Chambre au Loup, is not at all easy with the different markings (GR, PR (yellow, light blue or dark blue). This is where the smartphone app with the IGN map proves extremely useful for tracking our progress.
I think that the tour of the lake combined with the tour of the Chambre au Loup would be a good choice.
