De Plougonven aux deux menhirs par le bois de Gaspern

An entrance to Finistère through the Monts d'Arrée gateway: the small medieval town of Plougonven with its parish enclosure is very close to the Gaspern forest. At the southern end of this route, two menhirs stand in a field, seeking company. After extensive restoration, the 15th-century Mézédern manor house is still open to visitors in summer. Religious, secular and natural heritage are all on display here.

Description of the walk

The route starts at the car park of the post office and town hall.

(S/E) With your back to the post office, turn left and, at the first crossroads, turn left. Continue along this road until you reach the D9 departmental road. Cross it and continue straight ahead.

(1) Take the path on the right and continue along it. Cross the Route de L'Isle and continue straight ahead.

(2) Take the path on the left. At the houses, continue straight ahead and follow the same path, leaving the access road to Kerbriant on your left.

(3) Turn left onto a straight path and, at the road, turn right. Continue straight ahead at the crossroads. Pass Cosquer on your right and continue straight ahead.

(4) Take the path on the left, then turn right at the end of it.

(5) Turn left and continue straight ahead (the path climbs quite steeply for 800 metres).

(6) When you reach the road, continue straight ahead. Walk past Kerglaz and, at the exit, continue on the left. At the junction, turn right and you will immediately come to a crossroads: continue straight ahead (south).

(7) Pass near the Jarlot spring and continue towards the two menhirs.

(8) The first is close to the road, the second is in the meadow a little over 50 metres away. Take the D111 southwards. At the first crossroads, take the path on the left. Continue along the path to the water source.

(9) Turn left, then turn right onto the road towards Le Quilliou, which you will cross.

(10) Take the path on the left.

(11) Continue along the path on the right. When you reach the road, turn left.

(12) Leave the road and take the path on the right. Continue along this path when it makes a sharp left turn towards Gaspern Braz.

(13) Turn left. At the three-way junction (elevation 197), follow the road to the right.

(14) Turn right, then turn left to cross Kerhervé. In a sharp left-hand bend, when the path approaches a bridge, leave the path on the right, which leads to the Manoir de Mézedern, a private property that is off-limits to hikers, and continue on the left to rejoin the road.

(15) Follow it on the right until you reach the crossroads. Turn right towards Le Pradou and join the road that connects Meshir to Mézedern (the D9 departmental road). Take it on the right until you reach the Mézedern crossroads, marked by a calvary.

(16) Turn left and continue straight on until you reach the outskirts of Keralouant.

(17) In Keralouant, turn left onto Rue de l'Allée Verte and enter Plougonven. Continue straight ahead at the junction with Rue Courte. Note the parish enclosure (church, chapel, ossuary and calvary) on the right. Continue along the street to return to the car park where you started (S/E).

We walked this route on Sunday 12 April, and unfortunately the rain joined us for a good half an hour
But with our Gore-Tex jackets and umbrellas, we got through it without any major issues.
Whilst the route is generally easy to follow thanks to the GPX track, there are nevertheless two important points to note:
1 / As mentioned in the very first comment dated 21 May 2018 – six years ago now – the route is
difficult to follow precisely between points 5 and 6. I even think the difficulties have got worse over the last six years.
In fact, we managed to get through it without panicking thanks to the track we had on our app, which served as a guide
, but we didn’t hesitate to veer quite sharply to the right or left to avoid the vegetation. At
At certain points there isn’t really a path anymore, but you eventually find your way back onto it, as it winds its way through to end up between two meadows marked out by electric wires. Between the two rows of wires, a 60cm-wide passage… just wide enough.
2 / By forbidding people to pass through their property, the owners of the Mézerden manor have set a precedent in the neighbourhood.
For when you take the road on the right after point 15, you arrive at the crossroads of paths where it is no longer
possible to turn right to go to Pradou. As there is only one possible exit, we turn left towards
Garz ar Bélec, which takes us back along the route we took on the way out to the route’s starting point. This means
the entire end of the route that has been altered, and points 16 and 17 are no longer relevant.
The author should therefore amend their description to take account of this substantial change at the end.

it is not possible to walk alongside Mezerden Manor, and despite our research, the path that crosses the stream at point 15 has proved fruitless: there is no second path, and the first joins the road at Pontonars.
The highlight of the circuit is the two magnificent menhirs.

walk taken on 20 May 2018
please note that the path between markers 5 and 6 is now blocked. (Branches and brambles have been placed across the path at the top of the climb, and there are numerous private property signs along the path, apparently due to the replanting of a plot of land... ) I couldn't find a way around this obstacle and had to climb over the branches blocking the path and ignore the private property signs (for about 100 metres) before finding a path with no signs prohibiting access...
