The start of this hike is at the church in Poncey-sur-l'Ignon.
(S/E) Head north and take the small road that climbs between the wash house and the church (Rue Haute). When you reach the right-hand bend (elevation 466), go straight ahead on the path that cuts across the bend. Return to the small road and follow it to the left.
(1) Follow the D6 to the left (west). Cross the D971 and take the white path opposite.
(2) Join theGR®2coming from Chanceaux and continue west, following the red and white markings. Descend the valley and join the D103c.
(3) Take this road on the left and go around the Étang de la Grillande lake on the right.
(4) Still near the lake and before the safety barriers, turn left onto the path leading to a pumping station. Follow this wide path for about 1.5km, ignoring a few turnings on the left and heading up the valley.
(5) When this path turns slightly to the right as it climbs, take the path on the left followed by theGR®2(note: the markers are not very visible). After 200m, join a wide path, pass in front of a house and, before reaching the D103, take the path slightly to the left. You will reach the source of the Seine.
(6) Continue on theGR®2behind the source. Cross the D103 and continue opposite on a path following the sign for "Promenade sources-Seine".
(7) At the crossroads (triangular marker), turn left. Stay on theGR®2, ignoring all the paths branching off to the sides.
(8) After about 1 km, turn right onto a forest path. At the junction with a white path, take the path on the left. At the end, cross the D971 and follow the D26 towards Poncey-sur-l'Ignon.
(9) At the Sources de l'Ignon car park, take the path leading down to the springs.
(10) Continue on theGR®2, taking care to avoid the numerous springs that gush out over a distance of about 300 metres, making progress a little tricky (you'll only get your feet wet). You will then arrive at a place called Le Comet.
(11) Continue straight ahead (north, yellow markings) and leave theGR®2trail as it veers sharply to the right. Pass under a power line, cross the Ignon and rejoin the tarmac road.
(12) When you reach the village, take the D26 on the right. At the intersection with Rue Haute, take the latter on the left and head towards the church (S/E).
, the source of the Ignon, is inaccessible; see reviews.

Recommended for a friendly outing... However, please note: the route is a little far from Dijon (quite a long drive for Dijon residents).
