Sion travel guide

Switzerland · Top sights · trending spots

Sion has two hills and a fortress on each — the ruined Tourbillon, and Valère, whose basilica keeps the oldest playable organ in the world, built around 1435 and used for a festival every summer.

The Rhône valley below produces more wine than any other Swiss canton and gets more sun than anywhere in the country. Trains up the side valleys reach Zermatt and the Matterhorn in a couple of hours.
