What Travellers Say
Reviews Summary
Martinsloch is lauded as a fascinating natural wonder and a highlight of the Sardona Tectonic Arena, particularly for its unique geological formations and the breathtaking spectacle of the sun aligning through the rock hole. However, visitors consistently note that the trek is challenging and requires significant experience and proper equipment, making it less accessible for casual tourists or families with young children.
"This is an excellent trek, possibly a little challenging for distance if you want to complete it in a single day. The view of the tectonic plate layers is educational as well. A good way to understand the location is to see the documentary "How the Alps were formed". There is a Swiss mountain hut nearby in the Segnespass. Perfect location!!"
Clint Fernandez
"The Martinsloch, 19 meters wide and 22 meters high, is a breakthrough in the Tschingelhörner Alpine range. It is located just below the mountain ridge near the Segnes Pass on the border between the cantons of Graubünden and Glarus. Every autumn and spring, the sun shines through the hole for a few minutes directly onto the church in the village of Elm."

"A fascinating natural wonder that appears even more impressive up close. However, the climb is only recommended with appropriate equipment and experience."
