Hiking to the start 5'
Cross the dam and follow the road uphill. A little further up, you'll find the signs and path leading to the Col de Torrent.
This is an out-and-back trek. The route is obvious, and as soon as you're in the Alpine pastures, you can see all the way to the summit. No equipment is required, the only difficulty being the few passages on the final ridge, which are steep and exposed in places but not technically demanding.
All the hiking maps up to a scale of 25:000 are available online, free of charge, by downloading the Suis Map Mobile application onto your smartphone. With this free version, you can also download a 10km by 10km map for off-grid consultation.
Part 1: Col de Torrent (2910m, 1h30)
The trail twists and turns and climbs steadily until it reaches the Alpages de Torrent with a few huts. Continue along the wide path that climbs and soon reaches the Lac des Autannes. The pass to be reached and the Sasseneire peak are clearly visible. Continue along the well-marked footpath, which winds gently upwards through the combe to the Col de Torrent and the splendid view of the Val d'Hérens on the other side.
Part 2: Sasseneire (3254m, 1h)
Rather than attacking the ridge directly, descend 50m on the Val d'Hérens side to take the path leading off to the right into the scree (avoiding an exposed de-escalation passage on the ridge). The path crosses then climbs steeply in very short laces to reach the ridge. From here, we more or less follow the ridge on a comfortable path, sometimes flush with the void. It's a steep climb and you can feel it, especially as you pass the 3000m mark fairly quickly. The summit is further away than you can see. We end up on a narrower ridge, with a few easy cracks, to reach the summit. Impressive 360° views!
From the summit, follow the trail in the opposite direction to the Col de Torrent, the Lac des Autannes, the Alpages and the dam.
