We began at balise 2 right outside Breil. and climbed gently until balise 118, then followed the sign to Peine Haute bearing left and slowly descending.
Then, the hard part began. We began climbing and climbing and climbing. The last part after balise 439 climbed rather steeply to Peine Haute.
It was rather exposed to the sun at this point but still it was not a difficult trail. Instead of taking the predicted 2 1/2 hours to Peine Haute, it was a good 3 1/2 hours.
It then took exactly 3 hours to walk back to Breil.
Although not difficult, it was quite long and very up and down with ascents and descents. It is certainly not a hike for the summer, but a good sporting day for spring and fall. A hike to the stream would be pleasant and cut the time and effort substantially.
