Sagittarius
A Grimsel granite classic: low-angle slabs lead to the famous 6a+ crack pitches and a thin 6b traverse, then steeper, sculpted ground. Sustained at 5c/6a throughout.

Switzerland
The Haslital, between Guttannen and the Grimsel Pass, has glacier-polished granite slabs: Handegg, Gelmerfluh and the Räterichsbodensee Seeplatten. Bolting is generous on stainless steel, and most approaches from the pass road take 15 to 20 minutes. The season is June to September.

6b13 pitches400 m

Switzerland · Grimsel
Fourteen pitches up the Gelmerfluh next to Sagittarius, and by several accounts the better route: a knife-cut flake, a finger-to-hand crack worthy of Chamonix, corners, a pendulum and Grimsel slab, then easier quartz-veined walls to the top. Mostly 5c to 6a, with two short slab cruxes that almost everyone aids.
6c+14 pitches400 m

Switzerland · Grimsel
Glacier-polished slabs straight above the Räterichsboden dam. Four warm-up pitches lead to sustained 5b–5c slab and a short fissured roof (6a or A0).

Switzerland · Grimsel
A short, varied granite route up a pale, smooth pillar across the valley from the Handegg slabs: a corner crack, then friction and edge slabs that get harder pitch by pitch. Grades are stiff, and the last pitch is sustained and tricky. A good half day or uncertain-weather route with a 15-minute approach.
6a5 pitches200 m

Switzerland · Grimsel
Seven pitches of smooth, low-angle Grimsel granite, almost all pure friction, with two short steeper steps. Technically easy, but you have to trust your feet. A gentle introduction to Grimsel slab and to multipitch rope work.
