Getting there
The Simplon line serves Aigle, where the regional AOMC train leaves for Monthey, Val-d'Illiez and Champéry. The terminus sits fifty metres from the Champéry gondola, which is unusual in the mountains. Allow an hour and a half from Lausanne. By car, leave the A9 at Aigle and climb via Monthey; paid car parks wait at the entrance to Champéry.
Good to know: the valley road narrows and fills up fast on winter Saturdays. The train skips the entire queue, and children get to watch the valley go by.
