It is a full day: if you travel with small children, consider sleeping nearby and leaving Vulcania for the next day. ## Getting there from Spain Fly to Lyon: there are direct flights from Madrid, Barcelona, Valencia, Málaga and Seville. Collect the hire car and take the A89 towards Clermont-Ferrand to exit 26: Lemptégy is about 5 minutes away, roughly two hours twenty from Lyon. By car from Spain, along the A75 from La Jonquera, it is about 470 km to the plateau. ## The day, hour by hour 7:30 · Leave Lyon. By the A89 to exit 26.

If you travel from November to March, Vulcania is closed and Lemptégy opens from February: swap the afternoon for the Puy de Dôme train, which runs all year. ## Cómo llegar ### By car It is the practical way. Lemptégy and Vulcania are a few minutes from each other, and Montrodeix a quarter of an hour away. ### Without a car From Clermont-Ferrand there is a shuttle to Lemptégy from April to November, free at weekends, but the whole plan needs a car. ## Consejos ### Buy both tickets online Lemptégy asks for a booking up to three hours ahead and some Vulcania tickets are only sold on its website. ### Call Le Petit Graillou The hours change with the season. ### If you can, stay the night Vulcania needs a whole day; with a night in Orcines or Nébouzat you enjoy it without rushing. ## Preguntas frecuentes ### How much does the day cost? Between €65 and €85 per adult and between €50 and €65 per child, with both tickets and lunch, excluding the journey. ### Is there time to see Vulcania in an afternoon? Part of it. The park sells one-day and two-day tickets: with children, an afternoon falls short. ### Is it open in winter? Not entirely: Vulcania opens from late March to early November, and Lemptégy from February to early November. ### From what age? Lemptégy is free up to age 4 and Vulcania up to 3; both work with small children.
