Hexensteig Via Ferrata

Highlight • Climb

A very cool via ferrata in the rock. A fun route with a few surprises. We won't reveal any more. 😉 The approach can be made easier with an unusual chairlift.

Surenen Pass

Highlight • Mountain Pass

The ascent from Altdorf is steeper and special attention should be paid to the snow situation. The descent towards Engelberg is easier, not steep, and knees less.

Idyllic mountain lake - definitely looks more beautiful in good weather and blue skies.

The descents were very challenging on a bike in the snow, and not all of them were rideable for me. The scenery was incredibly beautiful, so the effort was worth it.

The first “half” from Blacken to Surenenpass is probably now S1 (easily drivable) thanks to “construction” measures.

The best place to have a picnic or a little rest, the area of the wall is very cold, since the sun never shines and there is a lot of wind. But from where the photo was taken, it is quite well insulated from the wind and it is where the sun shines the most.

"A via ferrata in the mountain? Yes, it has been there since July 2002 and, as is usual for legendary figures, it remained hidden for a long time. The via ferrata is located in a deep crevice on the Pfaffen, above the mountain station of the Chilcherberge open-air cable car. The path always runs inside the mountain on tree trunks and brackets and you overcome the approximately 80 meters of altitude using a Tyrolienne, where you also come across witches and black holes. A great mountain experience that starts with a great open-air ride on the cable car from 1974. In strong winds of 60 km/h or more, the ascent is not possible and even in normal winds it is an experience in itself." (https://www.bergsteigen.com/touren/klettersteig/hexensteig-silenen/)

What is the best time to visit the natural monuments around Altdorf (UR)?

The best time to visit largely depends on the activity. For hiking and exploring mountain passes and summits, late spring to early autumn (roughly May to October) is generally ideal, when trails are clear of snow and weather conditions are more stable. However, it's essential to check the snow situation for higher-altitude routes like Surenen Pass, as snowfields can persist into early summer.

Many natural attractions are accessible via mountain stations or cable cars, which often connect with public transport networks. For example, Fronalpstock Summit is accessible via a mountain station. It's recommended to check local public transport schedules and connections to specific trailheads or cable car stations for the monument you plan to visit.

Are there any hidden gems or lesser-known natural spots worth discovering?

While the main highlights are popular for good reason, the region offers many less-traveled paths. The 'schutz.wald.mensch' educational trail above Altdorf provides a unique perspective on the protective role of forests, and the 'hearing and experience trail' along the village stream offers a different sensory experience.
