Boucle des trois sommets

(D/A) Bibracte Museum car park
(1) Go up just behind the museum along a narrow path to the right, and hike along the side paths to the Rebout gate.
(2) Once you've reached the ancient Gallic town walls, admire the reconstruction of the "murus gallicus", a half-wood, half-stone wall-building technique common to the oppida.
Enter Bibracte. 2,000 years ago, it was a Gallic capital, founded at the end of the 2nd century BC by the Aedui. Abandoned and forgotten for two millennia, the town of Bibracte has now been reborn thanks to archaeologists. A 1,000-hectare setting of beech forests and viewpoints opening out over the Morvan countryside, all the way to Mont Blanc!
(3) Go straight along the road to the "pâture du Couvent", then left to the terrace, passing the Porrey.
(4) This is undoubtedly the grandest view in the Morvan.
(5) At "la terrasse", relax for a few minutes and enjoy the view - you've earned it!
Continue west until you come across the GR®13 signposted in red and white.
Turn left and follow it straight downhill. You are now leaving Beuvray...
Cross the small road and continue to follow the GR® as far as Petiton. In the hamlet, leave the GR® and turn right onto a signposted track, straight ahead for two kilometres, as far as the Eschenault crossroads on the D18.
Take the road opposite and cross l'Eschenault. After the houses, turn left onto a track as far as Les Cléments. You will come to the D500, turn right for a few metres and then left towards the north.
(6) Take the first signposted path on the left towards the sources of the Yonne.
Did you know that the Yonne flows through Paris?
On your left is Mont Preneley, 855m. You'll pass through a beautiful natural area, and once again you'll be taking a leap back in time as man has successively exploited and then abandoned the site of Mont Préneley and the sources of the Yonne for over 2,000 years. Along the way, follow the traces of the past that can be seen in the landscape, visit the peat bog, the springs, the timber rafting, the forest...
On leaving the landscaped site, towards the shelter, turn right onto the D300 road. You will pass the "Port des Lambert", a timber rafting port. Pick up the GR®13 on the left and follow it as far as "Pré du Massé", passing through a beautiful forest.
Take the D500 to the left as far as "l'ancienne maison du Bas Folin", then a track to the left.
Follow the "Route forestière de la Rosée".
There used to be a ski resort here. Haut-Folin was the closest ski resort to Paris. Set up by the French Alpine Club (CAF), a ski lift, an alpine ski slope and a chalet-restaurant existed until the late 1980s, but were abandoned due to a lack of snow and despite the presence of snow cannons. Go straight ahead on a yellow track. Here, take a track to the right, then another to the right and finally another to the left as far as the Etang de Préperny(7) . Take a small path to the left and walk around the pond to the left. Enjoy the peace and quiet of this magical spot.
At the chalet and wooden picnic table, take the track to the right, then quickly take a path that climbs slightly to the south and then right again. Follow this until you come to a forest track opposite which joins the GR®13, which you follow to the left. You will come to the Préperny forest road, which you will cross at a car park. Continue straight ahead, skirting the Fontaine Blanche stream and crossing it, which feeds the Goulette pond.
When you reach a track, turn left and then right onto a path that climbs gently up to La Croisette.
Continue as far as a car park and then follow the road to the right.
At junction 625, turn right onto a signposted track and follow it as far as "Crot Morin". Cross the hamlet by the road, pass in front of the cross, go straight on then take the road on the right following the red and yellow "GR® de Pays".
Cross a road then go straight on. Leave the GR® de Pays and turn right as far as "la Petite Chaux". Cross "la Chaux" and "la grande Chaux". At the end of the road, at the crossroads, take the signposted path on the right.
At "la Reinge", leave your path, go down the right-hand path, cross the stream, pass the mine shaft (beware of danger) and follow the path as far as Villechaise. Cross the hamlet to the left on the road, then take the right-hand path down to Argentolle. Cross the road heading south, go straight up and turn left onto the road (watch out for traffic) as far as the museum car park.
