Start from the Col de Bramont.
- Park your car near the sign: "Col de Bramont - Altitude 956m".
- Go in the direction of the "Col de Pourri Faing" (Marker = navy blue rectangle - GR531). Small pitfall to avoid: you leave the broad path for a narrow trail on the right after 20/25 minutes of walking, but the marker that remains the same is visible to those coming from the other direction. so you need to be vigilant!
- In front of the "Col of Pourri Faing" on the descent, go in the direction of the "Col de la Vierge" (Marker = blue circle).
- You cross the grasses of the "Viellie Montagne", and arrive at the forest "Chalet de l'Union".
- Turn in the direction of "Croix Louis" (Marker = red cross).
- At "Croix Louis" face the inscription on the cross and spot the entrance of the unmarked path behind it. On each side of this path, ONF lot numbers are clearly visible: 17 on the left, 16 on the right
- take this path until you reach NFB lot No. 137 to the left and 138 to the right. Just after, there's a tight bend on the left. Continue on this same path.
- You'll join a forest road. Follow it in the direction of the "Roche du Lac" (Marker = yellow circle)
- After reaching the Belvédère de la Roche du Lac, continue in the direction of "Collet Mansui - Lac des Corbeaux" (same marker).
- Then follow "Collet Mansui - Cornimont" (Markers = red cross and yellow circle).
- At "Collet Mansui" go in the direction of the "Lac des Corbeaux" (Markers = green rectangle and yellow circle).
- At the lake:1::, do not cross the embankment, but take the time to walk around the lake in a clockwise direction (30 minutes, completley flat).
- At the embankment, go in the direction of "Étang de Sèchemer". (Marker = green diamond).
- At the "Étang de Sechemer", go in the direction of "Col de la Vierge" (Marker = green triangle).
- After a "serious" climb back up you'll arrive at a forest road. Follow this in the direction of the Col de Bramont (Marker = yellow cross).
- Return to the start point.
