Enfer Doux


The Urner Alps - or Uri Alps - are located in the Uri district, in central Switzerland. The group is located between the three most popular passes in Switzerland: Sustenpass to the North, Furkapass to the South and Grimselpass to the West. This group is famous in reason of its compact and fine granite, that can stand comparison with Mont Blanc's one.

Gletschhorn main summit is an attractive granite peak located on the Gletschorn-Schöllenen ridge. On its left part it shows an obvious reddish spur of first-rate granite, projected to the Tiefengletscher, named Gletschhorn Spur, which has different climbing routes. Amongst these ones, Enfer Doux (Sweet Hell) is a little "pearl” - realized by the Remy brothers in 1985 - running along this fine buttress: you can climb up in a superlative environment on perfect rock. “Enfer doux” reddish granite has surprising intrusion of extra-white quartz. A must!

Getting There

Road Approach

The starting point to climb the Gletschhorn Spur is the Furka Pass road, running from Andermatt, a little town lying at St. Gotthard Tunnel northern exit, to Gletsch. From Andermatt take the road towards the Furkapass, reaching the Hotel Tiefenbach along the same road. A few hundred meters past the hotel take on the right-hand side a gravel toll road and follow it to the Tatsch parking m. 2270 (camping is not allowed).

***Enfer Doux report (French Scale)

Quick parties can climb the route in a long day directly from the Tatsch parking. Otherwise it’s also possible to spend the night to the Albert Heim Hutte SAC (Swiss Alpin Club) m. 2541, open in summer. From Tatsch a good trail leads to Albert Heim Hut (one hour); to reach directly the route, at a marked forking don’t follow the trail towards the hut on the right, but continue straight, then head towards left between big blocks, rising along the moraine and reaching a big cairn (“ometto”) near the Tiefengletscher’s beginning. Rising along the glacier towards right, after about 15 minutes of easy walk, an obvious orange spur departing from Gletschhorn summit ridge is clearly visible on your right-hand side (2,15 hours from Tatsch). Enfer Doux starting point is situated below a big white quartz intrusion, on the spur’s left section ; the route on the right is “Little Chamonix” (6b). The route is equipped with spaced bolts. Grades in French Scale.
L1 - Climb a little corner, then easier rocks – visible some big iron pegs, once situated at the starting point, now above, in consequence of the glacier’s strong retreat – to a belay into a curious quartz niche (4a).
L2 – Climb straightly a slab, then slantways toward right, finally a little crack (5c).
L3 – Long slantways toward left to a beautiful corner; climb the corner to its end (5c).

Wonderful granite...

L4 – Towards left go round an edge, climb straight up a slab, then a crack to a stance on a ledge with some blocks. Move towards left along the ledge, reaching a dihedral-crack. Stance below the crack (5a).
L5 – Up along the crack to a little ledge. Belay on the right end of the ledge (5c).
L6 – Up the wall climbing some little cracks, then slantways towards right to a slab. Climb straightly the slab (5a).
L7 – Climb some thin cracks on the right, then a clean crack, ending below the reddish final slab, which leads to the summit of the spur (5c+).
