About Lyon

The city grew rich on silk and banking, and its old quarters keep the hidden passageways, or traboules, that let merchants move between streets and courtyards. Fourvière's basilica and the Roman theatres sit on the hill above Vieux Lyon, while the Presqu'île holds the shopping and the main museum. May through September suits outdoor meals and river walks, though July and August can be hot; spring and early autumn are gentler for climbing the hill.
