The springs on the hillsides in Darois

 Park in the small car park on Rue du Château.

(S/E) Facing the castle, turn left, head down the cul-de-sac on the left, then take the path entrance on the left: a red sign indicates the GR®. Continue to the ruins of the old campsite.

(1) Leave the GR®, which heads down to the right, and take the path opposite, which climbs slightly through the woods. 

(2) At the junction of several paths, first turn left then right to follow a track. Stay on this path, ignoring all other junctions, and cross Champ Barthélémy to join the GR®2.

(3) Follow this path as it descends slightly to the right until you reach a junction where a sign marks the entrance to the Val Suzon Nature Reserve.

(4) Turn right here and head down into the woods, staying on the GR®2. Follow it as it veers to the left, taking care in wet weather on this stony, slippery descent. You’ll reach the Fontaine de la Trouvée, which has a stone basin built to collect the water. 

(5) Cross the fountain and continue along the GR®. Then let the path lead you down into the valley and back up the wide track on the left, to rejoin the main path you left at the edge of the nature reserve.

(6) Head down to the right along this wide, straight path through the forest. At the bottom, head down to the right and reach the Source des Chéneaux, which is signposted. This descent is steep and slippery in wet weather: a sign explains how these limestone springs are formed.

(7) From the spring’s basin, head down the main path that forms part of the GR® 7. Follow it back up to the right into the Combe des Chéneaux: this section climbs gently and is not difficult. You’ll reach a large junction in the valley with signposts.

(8) Let the GR®2 head off to the right and stay on the GR®7 by taking the valley on the left. Continue uphill: be careful, as there are a few slightly steep sections and fallen trees, until you reach the Lavoir de Darois, situated slightly set back to the left of the path. A beautiful stone structure, perfectly restored, which collects water from the small cliff.

(9) Return to the GR®7 path and turn left to complete the climb and reach the ruins of the old campsite.

(1) Once back at this point, turn left to reach the end point at the small car park on Rue du Château (S/E). 

I recommend following the route described on rainy or damp days, as the descent from the Lavoir de Darois is the most difficult.
There is a bread and cheese vending machine in Darois, as well as a restaurant.
