The "Gargellner Windows" were formed by the collision of igneous rock and limestone. As a result, rounded, eroded mountain shapes are found directly next to bizarre peaks. Daphne blooms in the rock crevices, alpine roses grow next to orchids, and swamp flora spreads in small ponds.
The "Gargellner Windows" can be seen near the Rongg waterfall, in the Rongg and Röbibach gorges, and above the house Rüti.
