This spectacular 60 metre long suspension bridge on the Saas-Almagell adventure trail must not be overloaded. You should therefore only cross it in pairs.
Just over two hours and almost 400 metres in altitude are now behind us. Just a few metres ahead of us is our destination: the cosy Almagellerhütte.
Marco Barneveld takes a breather and enjoys the view of the unfortunately somewhat cloudy Täschhorn, Dom and Lenzspitze mountains.
The snow-covered section around ‘Triftgrätji’ follows the Alpine flower promenade, which presents around 240 different types of flowers, including edelweiss and gentian, when they are in bloom. Now, unfortunately, only a fraction of them.

Overnight hostel and starting point for glacier hikes: The Gletscherstube.
The hiking trail up to the Eggishorn offers spectacular views of the Aletsch Glacier time and again thanks to the glorious weather.
