After the retreat of the last glacier 10,000 years ago, the Rhine River started to break through the rock masses of the Flims Rock Slide. The river’screated the nature spectacle of the Ruinaulta (Upper Rhine Gorge).

The Ruinaulta is often referred to as the “Swiss Grand Canyon”. The observation platform “Il Spir” (Rhaeto Romanic for Eurasian swift) offers the visitor a unique 180-degree panoramic view over the Ruinaulta. The platform consistsof a single pillar that is anchored in two places. The pillar, held back by a tow cable, rises between the pines and leans over the gorge. A triangular platform of pine wood sits atop the pillar, giving the structure the shape of a swift. The platform is easily reached from Flims by foot in less than an hour. The walk to Restaurant Conn, which serves local specialties, takes five minutes
