(S/E) Start from the church in Mévoisins, which is in the heart of the village. Walk up Rue de la Liberté, leaving the church on your right, and cross the level crossing. Immediately after the level crossing, take a small street on the left that runs alongside the leisure ground, pass a small tunnel on the left and take the path that starts in front of it. The path runs alongside the railway line for a while.
(1) When you reach a pine forest, the path forks: take the right fork. The path climbs slightly, surrounded by woods. At the top of the path, before leaving the woods, you will find a solid hut on your left, set back from the path ("Cabane de Tarzan" on the front). The path continues and goes around another grove.
(2) At the corner of the copse, follow the path on the right, which descends slightly to join the D329-4.
(3) Follow this road to the left for 100 metres. At the end of the copse on the right-hand side, leave the road and take the path on the right. Walk around the copse, which is home to many birds. Then rejoin the road.
(3) Follow the road to the left and pass in front of the Mévoisins menhir.
(4) About 200 metres after the menhir and just before a copse, take the path on the left (south-east). Follow the path to a T-junction: then first turn right then left to continue south-east. You will reach a crossroads about 500 metres further on.
(5) Turn left and head uphill. You will arrive at the access point to the dolmen (information board in a field).
(6) The Pierre Frite Dolmen is located in a field on the left. This is a plot of land that has been left uncultivated and is kept accessible for visitors. Leave the path and enter the plot, heading towards the information board. Retrace your steps.
(6) Returning from the dolmen, follow the path you came along to the left. After about 100 metres, take the path on the right.
(7) At the end, turn right onto Chemin Creux (its name), which is wooded on the left. After about 200 metres, take the path on the left (south-east). On a hillock, first turn left then right and descend, keeping south-east.
(8) Cross a small road and continue straight ahead to reach a small wooded area. Continue along the path, still heading south-east, until you reach a very small road, the D329. Follow this road to the left for about 50 metres until you reach a small wayside shrine with a wooden cross.
(9) Then take the path on the right that passes behind the wayside shrine. From here, in summer, enjoy the direct view of the gliders taking off. Descend to the next intersection after a few groves. Then turn onto the path on the left and join a new small road, the D329-1.
(10) Follow this rarely used road to the right. At the crossroads (elevation 140), continue straight ahead, climbing towards the flying club. At the highest point (153m), ignore the turn-off on the right, continue south and cross a wooded area (note the Bailleau-Armenonville flying club on the right). Cross the bridge over the Vélo-rail and head for the Ferme des Bordes.
(11) At the three-way junction, turn right. In a left-hand bend (elevation 147), leave the road and take the path on the right. Reach the Vélo-rail.
(12) Cross the old railway line: be careful, this line is operated by the Vélorail du Pays Chartrain association, so don't be caught out when crossing. Continue along the path opposite. Follow the path to the left as it goes around the southern runway of the flying club (which is hardly ever used).
(13) At the crossroads at the end of the runway, turn right. Turn right again and continue along the runway, in the opposite direction to before.
(14) After going around the southern runway, take the path on the left and enter the woods.
(15) At the fork, take the left path between Bois Deligneris and Bois du Séminaire. Continue for several hundred metres, cross a small road, the D106-2, and continue straight ahead.
(16) Cross the D329. About 20 metres further on, at a fork, take the path on the left. Follow this path for about 1.2 km, ignoring the paths branching off to the sides.
Be careful, this point is a little tricky. As the main path bends to the right, turn left and go further into the undergrowth. Follow what looks like a boundary between plots of land, i.e. a very narrow path shaped like a gutter. After about 500 metres, you will come to a large path blocked by barbed wire. This is private land and you will need to go around it on the left, still following the small path that descends slightly. The path then widens.
(18) Turn left onto the path that eventually descends between Les Bruyères and La Vigne aux Vaches until you reach a very small road.
(19) Follow theGRP® de la Vallée de l'Eure by turning right and going uphill. After 50 metres, there is a fork in the path: stay on theGRP® on the right. Continue straight ahead. Cross a road: be careful, as drivers have poor visibility on this section and may be travelling at speed. Continue straight ahead for about 50 metres.
(20) At the crossroads, continue straight ahead (leaving theGRP® trail to your left). About 500 metres further on, you will emerge from the undergrowth and enjoy a beautiful view of the Eure Valley. The path descends to the railway line and takes you to the level crossing. Turn left to return to the church (S/E).
