Park in the car park of the church and town hall of Éclose.
(S/E) Head east towards "Chateauvilain" (sign).
(1) Cross the D1085, where there is a traffic light, and continue straight ahead, still heading towards Châteauvilain (signposted).
(2) Take the first right at an iron cross (towards Les Planches). Ignore a small road on the right leading to a housing estate. Take the next road on the right (signposted Route des Grabissières).
Go past this hamlet and, after a right-hand bend at the top of the hill, take the dirt track opposite you. Further on, take the left-hand track. This will bring you back to the small road that leads to the hamlet of Le Marc (concrete cross hidden on the left).
Take the gravel path on the right (yellow markings) and you will quickly reach a fork.
(3) Take the left fork (signposted "Le Crépon" - direction "Belmont Eglise"). Curiously, a blue sign indicates the place called "Le Marc" 400 metres away, even though we have just passed through it (?!)
Enter the forest and go straight ahead at the crossroads.
(4) Take the first grassy path on the right. At a fork, continue on the left. Follow your path, ignoring those that branch off to the right or left, until it meets a path at a 90° angle (T-junction).
(5) Turn left. Very quickly, your path will veer sharply to the right. Ignore a small path that branches off to the left. You will come to another T-junction. Turn right and pass under a power line. On your left, you will see a clearing currently covered with ferns (June 2016). Follow the path until you leave the forest.
(6) Ignore the first path coming from the field on the right and take a small road on the right. It passes under a high-voltage power line. Follow the edge of the forest, following its twists and turns. When you cross a strip of woodland (yes, really...), continue on the left.
(7) You will then come to a small road that you should take to the left. Go up a small hill and, after passing a small mound on the right and before returning to the high-voltage power line, take the wide gravel path on the right.
(8) When you arrive directly below the power line, turn right. When you leave the power line behind, leave an old path on the left and take the next one (signposted "Plan Martin" - direction "Éclose Mairie").
(9) You will rejoin the D1085, which you should cross very carefully. Be careful! Traffic moves very fast here.
Follow the small road that climbs up opposite, then take the first right fairly quickly. The road continues to climb, offering views of the Ain mountains, with glimpses of Mont du Chat and Chartreuse.
Our small road seems to end in the courtyard of a house. Not so! It turns into a grassy path that branches off to the left.
(10) You come to a T-junction. Turn right. Then, a little further on, turn right again. Your path turns right again. You come to a small road and a hamlet. Continue straight ahead, then turn right to reach a priority sign.
(11) Cross over to take the small road opposite, even though there is a yellow cross. You will come to a stop sign. Continue to the right (watch out for cars).
(12) When the road turns right, continue straight ahead on the small road that leads to the cemetery, then to the church where you will find the car park (S/E).

A lovely little stroll in the shade, ideal when it's hot:
