Sunniggrätli

Sunniggrätli, also written Sunniggrat or Sunnig Grätli, is a mountain ridge near Gurtnellen in the canton of Uri, in the Urner Alps. Its high point sits at roughly 2,034 m and offers wide views over central Switzerland and the Gotthard region. It suits hikers who want a panoramic summit without any climbing.

How do you get to Sunniggrätli?

The most common start is the top station of the Intschibahn cable car at Arnisee. From there, easy T2 mountain paths lead up through rooty forest, across a raised moor and finally over rocky ground. Allow 1.5 to 2.5 hours for the ascent.

A longer option begins in Gurtnellen village and takes about four hours. Hiiker also lists a 6.9 km loop that starts and ends in Gurtnellen, but it rates that route as extra difficult, so it is for experienced walkers. A third approach starts at the Leutschachhütte (2,208 m) and follows the Langchälengrätli ridge for about 4.4 km with around 270 m of ascent.

What will you see on the way?

The summit looks out over the central Swiss Alps toward the Gotthard. The landscape changes as you climb, from forest to moorland to rocky ridge. A well-known circuit runs Arnisee – Sunniggrat – Leutschachtal – Arnisee and is graded T2–T3. The drop into the Leutschachtal is steep and slippery when wet, so wear good boots and take your time.

Where can you eat and rest?

There are two stops for a meal: the facilities at Arnisee and the Sunniggrathütte (also called Sunniggrätlihütte). The hut is seasonal, opening in May or June and closing in October depending on snow.

When should you go?

Aim for late spring to early autumn, when the hut is open and the trail is clear of snow. Check the Intschibahn timetable and current trail conditions before setting out.

What else is near Gurtnellen?

Families can try the short Stäubenweg loop from Gurtnellen-Wiler (740 m). It takes about 1.5 hours, climbs roughly 230 m, and passes waterfalls such as the Dreistäubenfall as well as the Stäubenkapelle chapel.
