The starting point is in the hamlet of Uffel (located about 2 km from Dortan via the RD936 road) at the recycling facilities (parking available).
(S/E) Head towards Rue du Four, then fairly quickly take a path on the left uphill (no sign): it climbs gently at the bottom of a small valley.
Shortly after a small pass, you will reach a path.
(1) Turn right uphill at the fork.
The path then climbs more steeply (visible yellow markings). You arrive at Col de la Tendue, where you can go straight ahead to a beautiful viewpoint over Lac de Coiselet (be careful, as the access is on the edge of a ravine).
Return to the pass.
(2) Take the path uphill to the right, following the yellow markings: the slope is quite steep in places, with a particularly tricky section near a small cliff secured by a cable (take care). You will reach the Belvédère de la Pierre-qui-Vire viewpoint overlooking Lake Coiselet (be careful of the nearby cliff).
(3) Continue along the path and, not far away, you will see the Pierre qui Vire. Turn right onto the path towards Emondeau, heading uphill (yellow markings). Not far from the 700 m contour line, there is another viewpoint.
Further on, you will come to a fork in the path.
(4) Turn left towards Maissiat (2.6 km) to take a gently sloping path downhill (yellow markings).
A little further down, go straight ahead at another fork (towards Maissiat 0.5 km) to reach the hamlet of Maissiat d'en Haut.
(5) Take the small road on the left, then immediately left again to continue down a sloping path (towards Dortan). Further on, continue straight ahead on the small road.
Take thefirst road on the right towards Cascade de la Combe and Vouais (yellow markings). Not far away, continue along the path on the left towards Cascade de la Combe to reach it and admire a beautiful sugar loaf rock formed from limestone concretions.
(6) Return along the stream. At the fork, continue straight ahead towards Dortan.
The trail joins a small road. Take it on the left towards Maissiat (0.2 km). Enter the hamlet of Maissiat d'en Bas.
(7) Head right, then immediately left, then left again (towards Uffel and La Pierre qui Vire). Continue along a carriage road until you reach a fork. Go straight ahead towards Col de la Tendue, Uffel and La Pierre qui Vire.
(8) At a fork, take the path on the right to reach a viewpoint (beautiful view of the Bienne Valley). Return to the fork and turn right, following the yellow markings.
(9) At the fork, continue straight ahead towards Uffel.
Once you reach the road, take it to the left to return to the starting point (S/E).
