Ce parcours is accessible in Hiking and Moutain Biking.

An enchanting place! Three natural lakes with turquoise and emerald waters in a green setting, bordered by exceptional wetlands for an accessible family stroll.

The lakes intrigue, refresh and soothe. Surrounded by a remarkable natural and historical heritage, they invite you to go around them to discover it: ponds, reed beds, marshes, dry lawns... so much diversity!


Parking :

Mont des ifs car park near the RD75 between Le Frasnois and Pont de la Chaux.


Itinerary:

From the car park, carefully cross the D 75 road (yellow markings) and reach the Monts des Ifs crossroads.

Follow the path to the right below the road and reach the head of LAC DU PETIT MACLU.

Take the good stony path which successively runs along the lakes, namely the Petit Maclu, the Grand Maclu then which, after a small forest sector, comes out at the edge of Lake Ilay before joining the Chemin des lacs.

Continue the path on the right (white-red markings) until Lac d'Ilay.

Continue along the D 75 road to the right (yellow markings), pass a pasture (barriers to contain livestock) and find below the road the grassy path which leads to the entrance to the village of Frasnois, at the Chemin des Bornes crossroads. .

Take the right path for 350 meters on the right, bordered by meadows. At the crow's feet, continue the path on the left which joins the D 75 road.

Take a path on the right that leaves the road to reach Mont des Ifs.

Cross the road again (be careful) to find the Monts des Ifs car park.


Recommendations:

Take care when crossing the road at the start, to reach the Mont des Ifs crossroads.

The wetlands surrounding the lakes are preserved and fragile natural spaces. Please do not leave the marked trails and respect the tranquility of the area.

Cows and horses maintain these areas and change pens during the season. These animals are very hardy: do not try to approach them or feed them, this could harm their health and your safety.

Wildflowers are beautiful, they can be rare and protected and often wilt quickly. Don't pick them! They will delight future hikers.

Please keep your dog on a leash if you have one.
