Circular walk starting from Foncine-le-Bas

A beautiful, long walk taking in popular tourist spots such as the Gorges de la Saine, the Belvédère du Bulay, the Roche Fendue and its viewpoint, the Couillou viewpoint, and the springs and waterfalls of the Leat de La Ruine.
However, one section of this route requires a good sense of direction, as it involves walking off the beaten track along a steep slope and a sharp descent before fording a stream. This section is necessary to bypass a private property.

Description of the walk

Park in the car park at Foncine-le-Bas, Rue des Douanets, before the River Saine.

(S/E) Head left, cross the viaduct over the River Saine and reach a junction. Then turn left onto the old tram line and follow it to a Y-junction.

(1) Keep left on this road. Walk alongside the stunning Gorges de la Saine and go through the tunnel. Continue through this magnificent landscape on theGR®559A, marked in white and red. Cross the Ruisseau d’entre Côtes and carry on until you reach, further on, a junction with a tarmac road, near Les Planches-en-Montagne.

(2) Turn right onto Rue du Paradis and you’ll come to a hairpin bend.

(3) Head slightly to the right to enter the forest. You’ll soon reach a junction; keep to the right to follow the left bank of the Ruisseau de Poutin. At the next fork, keep left, staying on the left bank of the Ruisseau de Poutin. Cross the stream and head towards the edge of the meadows.

(4) Continue to the right, at the foot of the scree slopes. At the end of a curved section in the woods, look out for a path with a ‘private property’ sign – be careful here: no entry.

(5) From here, you’ll be walking by sight. Follow the narrow track heading south-west for about a hundred metres. After the boulders on the left, in a small valley, head straight up the slope. At the top, head north-east down the slope towards the stream. Cross it wherever you can and join the marked path on the other bank.
Note for this section: this slightly tricky part of the route is necessary to avoid a long detour. You can use the app to help you find the easiest route.

(6) Turn left onto theGRP®, heading north-east. Pass by the Grotte de la Mine d’Or (or Trou du Diable) and the Waterfall des Orpailleurs. Continue until you reach a lovely clearing where a charming hunting lodge is situated.

(7) Carry on across the meadow, enter the forest and cross the Ruisseau d’entre Côtes; you’ll soon reach a junction with a forest track branching off to the right.

(8) Turn right onto theGR®509, marked in white and red. Walk a few metres along the road to reach the start of the path leading to the Bulay viewpoint.

(9) Climb the steps on the left to reach the viewpoint. Enjoy the view, then head back, veering slightly to the left onto theGR® 509 and the GTJ. At the junction with the road, keep left on theGR®. At the cross-country ski trail car park, continue along theGR®. You’ll reach the junction with the nature trail.

(10) Turn right onto theGR® to reach the Belvédère de la Roche Fendue viewpoint.

(11) Continue to the right, then turn sharply 90° to the right onto the GR®. Head down through the forest to reach a four-way junction at the Belvédère de Couillou viewpoint.

(12) Cross the road and head uphill straight ahead to reach the radio mast and a developed area.

(13) Return to the previous crossroads.

::12: Turn right back onto theGR®, walk past a farm and reach the entrance to the hamlet of Les Ruines.

(14) Leave theGR® here and turn left (south-west) onto a shaded path between the hedges. You will then enter a pasture. Follow this path through the meadows, then through the copses. Go through the gate and head downhill to find a path near the Source du Leat de la Ruine.

(15) Here you can turn right to reach this spring; please check carefully that it is accessible. Then continue along the left bank of this stream. At the waterfall, as the slope becomes too steep, move away from the stream and head south. Continue to the left to return to the tram line junction you passed on the way out.

(1) Turn right and follow the route you took on the way there in the opposite direction, heading back to the car park on Rue des Douanets (S/E).

The route between control points 5 and 6 is not detailed or precise enough. It may be very difficult for some people.
The section between points 12/13 and 14 is uninteresting, consisting almost entirely of stair steps and passing through houses (a new neighbourhood?).
The route from 14 to 15 starts off very well but then becomes haphazard and lacks detail. We got lost and ended up crossing fields, making up our own route to find point 15.
Perhaps point 14 should be removed and we should go directly from 13 to 15 via a different route?

A magnificent, very long and varied walk. Just need to fine-tune two or three sections. But often there’s little or no signposting in places away from the main paths.

Thanks, Visorando!

Hello @cuzcodom,
thank you for your feedback on this walk; it’s true that you must have had a bit of ‘fun’ in the snow to avoid the private road – quite a steep little climb…
See you soon on other walking trails

A really lovely walk: very varied, with some stunning views (didn’t see Mont Blanc, boo)
Getting round the private road was quite a challenge as 20 cm of snow had fallen during the week, which added a bit of spice to the mix.... I wonder if taking the PR path leading to the Refuge du Paradis might be a good option to avoid this snag?
In any case, thank you for this lovely route.

Hello,

A lovely walk offering the chance to discover some tourist attractions. A peaceful route with few other walkers.
The off-trail section requires a bit of care, but crossing the stream is lovely and the area is truly unspoilt.
It was brilliant! Thanks for sharing this route.
