Flims – Cassonsgrat

Cassonsgrat above Flims is a high-alpine site in the Graubünden Alps at about 2,664 m, good for thermals, ridge soaring, cross-country flying and reached on foot — the source notes that as of a 2015 update the cable car serving this launch had been dismantled, leaving a hike up from Flims or Naraus as the way in, so it's worth checking locally whether that has changed since. The launch works in south and southwest wind. This is a demanding site: strong foehn wind is flagged as a real hazard here, and the described landing zone in Flims sits on a downhill slope, which raises the difficulty of every landing. There are also local flight restrictions around the nearby Flimserstein that pilots need to know before flying in the area, and Swiss airspace rules in general are complex enough to be worth checking in detail beforehand. A serious high-mountain flight for pilots already comfortable with foehn conditions and a tricky landing, not a first outing.
