Stellihorn

Stellihorn is a 3,436 m summit in the Pennine Alps, rising above the Saas valley in the Swiss canton of Valais, south of the village of Saas-Almagell. It is a serious objective for experienced alpinists, and for everyone else it is mainly a striking part of the skyline above Lake Mattmark.

Where is Stellihorn?

The peak belongs to the Weissmies massif and sits south of that well-known 4,000-metre mountain. To the north it drops towards the upper Saas valley and the Mattmark reservoir (about 2,197 m). The Italian border is close, and the main pass nearby is the Antrona Pass (2,838 m), which links the Saas valley with Italy's Antrona valley. A glacier called Nollen covers the northern flank.

What can you see in the area?

Even if you are not climbing, the Mattmark area is worth a visit. From the lake and dam you look across a high-alpine scene of rock walls, ice tongues and the peaks around Weissmies. Saas-Fee's summer activity maps show Stellihorn alongside the Britanniahütte (an SAC hut at about 3,030 m) and Mattmark, which makes it easy to pick out among its neighbours.

Trails lead from Saas-Almagell towards Mattmark, where routes into the massif begin. The surroundings suit full-day walks, and higher up, near hut level, you are in genuine mountaineering terrain.

Can you climb Stellihorn?

Yes, but there is no easy tourist path. The summit sees few visitors, so you are unlikely to meet crowds. The ascent calls for alpine experience: rock-climbing sections, short rope work and a crossing of crevassed glacier. In winter it is sometimes a ski-touring target, with the descent heading back towards Mattmark. Without training, glacier gear and local knowledge, stick to valley walks or hire a mountain guide.

How do you get there?

Saas-Almagell in the Saas valley is the base. The valley branches off the Rhône valley in Valais, and the road from Visp runs up the Saastal to the village. From there the road continues to Lake Mattmark, the starting point for most trips into this area. In summer, check current bus connections and parking availability.

When should you go?

Summer walks around Mattmark are best from July to September, when trails are clear of snow. Attempts on the summit depend on glacier conditions and weather, so check the forecast and conditions close to your date. In winter and spring the area draws ski tourers, and avalanche assessment is essential.
