Starting point: Fressin, car park at the edge of La Planquette, at the junction of Grand Rue and Rue du Mont Hulain.
(S/E) Take the small staircase leading to Rue du Mont Hulain, turn left, then immediately right onto the D154 (Rue de Planques). 200 m further on, turn right towards the footbridge over the Planquette (witch statue). The grassy path leads to a small road which you follow to the right. At the crossroads, continue straight ahead into Rue du Marais.
(1) At the T-junction, turn left (Rue de l'Enfer). When the road turns right, leave it and take the path that climbs opposite. It joins a good path, which you follow to the right.
(2) Turn onto thesecond path on the right (be careful, this path is not very visible; here, the map is inaccurate at 1:25,000 but is accurate when zoomed in further). It turns left and heads towards the edge of the woods. Join a small road and follow it straight ahead. Ignore the small road coming from the right and take thefirst road on the left to follow the edge of the woods.
(3) At the crossroads after the woods, turn left and climb for a good kilometre to Les Argillettes (elevation 103).
(4) Take the hairpin bend on the right to finish the ascent of Mont Miracle. Then descend. Ignore the path on the right and reach a crossroads.
(5) Turn right (it is signposted) to descend a beautiful vaulted path. Reach a crossroads. Follow the small road on the left. Pass a crossroads (Chapel) and reach the D 106. Follow it to the right and reach a crossroads. Take the D154 on the left. 200 m further on, turn right and head for La Planquette.
(6) Cross it and then walk along it on the left. Atthe first crossroads, continue straight ahead. Towards the end, I recommend leaving the wide path (shortly after a footbridge) to follow the path that runs alongside the river. You will then arrive near an old mill. A footbridge will take you back to the wide path.
(7) At thesecond crossroads, turn right onto Rue du Presbytère (you are now in Cavron-Saint-Martin). Keep going in the same direction (north) and climb for about 1.5 km until you reach a T-junction. Turn right and you will reach the D108.
(8) Follow it to the right for 250 m. Take a good path on the left (Vallée aux Crapauds) and, after 150 m, turn right (see practical information) to reach the church of Wambercourt. Keep going in the same direction to reach the D154 (chapel).
(9) Follow it for 100 m on the left, then turn left onto a small road (Rue de Lebiez) and climb for about 2 km. You will arrive near a reservoir (horrible, but what a landmark!). Make a sharp right turn.
(10) After a few metres, turn right onto a pretty path (the first few metres are a little steep). Stay on this generally well-maintained path, marked with yellow and mountain bike signs, for about 1 km (nice hollow path on the left). Reach a path and follow it straight ahead (towards the woods) to reach a T-junction at the edge of the Bois de Fressin (signposted and explanatory sign).
(11) Turn left, then immediately right to enter the woods (metal barrier). You will come to a wide uphill path. You now have a choice:
- The easiest option is to take this path: the slope is steady and not too difficult. At the top, turn right to continue along the edge of the forest (PR® and mountain bike markings).
- For the more adventurous (and daring), look for mountain bike markings on a tree at the foot of the hill, inviting you to turn right (August 2024: I have cleared the area, the entrance is clear). Follow them to reach a narrow, clearly marked path along the edge of the forest (this is the old marked trail). This path is quickly blocked by two fallen trees that are easy to pass, then a third that you go around on the right to find the path again. After about 300 metres of flat ground, you will come to a steep slope. It is blocked by two tree trunks (one in the middle and one at the top). The first is easy to get past, but the second is a little more difficult. At the top, turn right to stay on the edge of the forest.
From there, follow the excellent yellow markings. The path is uneven but in good condition and well marked. You will reach a crossroads of Promenade and Randonnée paths (barrier and signpost).
(12) Leave the Planquette trail (which continues opposite towards a barrier and the D108) and turn left onto the Chevrette trail. Staying on the edge of the forest, pass above the ruins of Fressin Castle before crossing a metal barrier and then a junction (note that the PR® route on the IGN map is incorrect in this section).
(13) Turn left towards the house. Then take the path (to the right of the two-headed dog) that seems to lead into the garden (it is still marked in yellow). Stay on the edge of the forest. After about 1 km, you will reach a small road which you follow to the left until you reach a crossroads.
(14) Turn right, then immediately right into Petite Rue Haute, which quickly turns into a good path. At the crossroads, turn right into Rue Noire, which quickly turns into a grassy path. At the next crossroads, continue straight ahead towards the church and the D 154. Follow it to the left (passing in front of a large bottle) to reach the car park (S/E).
