Glarus Thrust at Martin's Hole

Two weak layers intersect in the legendary Martin's Hole: a soft, flat, dark marl layer and a steep fracture surface. Erosion in this area was able to quickly remove the limestone, creating Martin's Hole with a diameter of more than 15 metres. On two days each in spring (13-14 March) and autumn (1-2 October), the sun's rays hit the church of Elm through Martin's Hole.

Directions:

Only very experienced hikers should attempt the approach to the Martinsloch. From Flims, take the FlemXpress to the Segnes station. From there, cross the impressive landscape of the Lower Segnesboden, always keeping the Tschingelhörner in sight. After mastering the first ascent from the Lower Segnesboden to a higher plateau, you’ll be able to see the Martinsloch.

From this rocky plateau, you now head straight towards the Martinsloch, which lies directly ahead. The route (T5 level on the Flims side) follows an unmarked trail through a steep scree slope up to the Martinsloch. The path is prone to falling rocks and should only be attempted with appropriate equipment.

From the Martinsloch, you are rewarded with a magnificent view of the surrounding peaks. You now have the option to descend directly to Elm or turn back and enjoy a stop for a delicious Kaiserschmarrn at the Mountain Lodge on the Segnes Pass, located just a few hundred meters to the right of the Martinsloch.
