In reply to Connolly8684:
If there's a early autumn heatwave, head for the crag at Simplon Dorf (just off the Simplon Pass, near the Italian border). It's high, at almost 2000m asl, steep well bolted schist, grades 6a-8a (mainly 6c-7b). Fabulous position in an open pine woodland with views to 4000m peaks. Oner of the very best summer sport crags in Switzerland. Fab coffee and bread shop in the village too.
