Day 1 — Sion: Bisse de Clavau and vineyard terraces above the Rhône Valley
- 🥾 On the first day, begin your introduction to Valais with one of the region’s most beautiful yet accessible walks — Bisse de Clavau. This is a trail along a historic irrigation channel among dry stone walls, terraced vineyards, and wide views over the Rhône Valley and Alpine slopes. The active part of the day is about 3–4 hours at an easy pace, roughly 8–10 km, with moderate elevation gain of around 200–300 m depending on the start and return point. Difficulty is moderate: the route is well known, marked, and popular, with no climbing sections, no glaciers, and no special equipment; an ordinary traveler only needs comfortable shoes, water, and sun protection. Along the way, you are not walking a wild high-mountain trail, but a safe pedestrian route along the bisse, where the main pleasure is the light, the vineyards, the dry warm air, and the beautiful panoramas. In May and June it is especially green here, while in July–September it is important to set out early because of the heat: this slope is considered very sunny and dry. After rain, the stone sections and dirt path can be slippery, and in late October it is worth checking the trail condition and transport schedules in advance. Overnight in Sion so as not to overload the first day with transfers.
