Rondje Château de Montluel en Grand Parc de Miribel-Jonage

The ride

Roll out of Thil and the road soon rises to Fort de Vancia, then dips past the lake at Étang Prarieux. Castles stack up along the way — Château du Montellier and Château de Joyeux — before the route follows La Sereine and swings by Château de Montluel. The Grand Parc de Miribel-Jonage nature reserve and the Canal de Miribel carry you toward home, all 74.6 km of it paved.
