Starting from Fionnay, this trail begins with a short ascent on a path that quickly joins the Dranse and enters the Val de Bagnes. From the top of the small village of Bonatchiesse, the ascent ries steeply to the Col des Otanes. The path initially winds its way through forests and green pastures and continues through a rocky alpine landscape up to the pass. At the Col des Otanes, the landscape mainly consists of rock and ice with the Grand Combin above and the Corbassière glacier below. Start heading down to the FXB Panossière hut, then continue your way along the moraine to the Bisse de Corbassière, which you will follow before going down through the forest to Fionnay. Cross the bridge to return to your starting point.
Taste the famous almond or lemon pies at the FXB Panossière Cabin.

For all trails:
Use marked trails only, and take note of all signposting – for both your own safety as well as that of grazing animals and to avoid disturbing wildlife.
Close gates after passing through.
Please treat other trail users, as well as the plants and animals, with respect.
For mountain trails:
Take extra care protecting yourself from the sun at high altitudes. UV radiation can be exceptionally strong, even in cloudy weather.
Plan your trail carefully: take the fitness level of each participant, weather forecast and season into consideration.
Weather conditions can change quickly in the mountains, without warning. Appropriate clothing is therefore essential, along with adequate supplies of food and water. In case of uncertain weather conditions, turn back in good time.
Inform others of the route you plan to take. Whenever possible, avoid going alone.
Take note of warning signs indicating the constant danger in river beds and along watercourses below dams and reservoirs: water levels may rise rapidly without warning.
From the village of Fionnay, take the path that runs along the Dranse de Bagnes towards Bonatchiesse, then branch off to begin a substantial 1,400 meter ascent. Pass through La Tseumette, where you’ll encounter another alpine trail starting from Mauvoisin, and which joins yours during the ascent to the Col des Otanes. Once over this rocky pass, the rest of the route is downhill. Head to the FXB Panossière hut first then join the Bisse de Corbassière before your final descent through the woods to Fionnay.
