What You See

The fort sits at 1,150 metres in the Haut-Jura Regional Natural Park, in the middle of the village of Les Rousses near the Swiss border. Its thick walls and rock galleries now hold more than 140,000 wheels of Comté, aged by Juraflore, part of Fromageries Arnaud. The guide takes you into the Charles Arnaud cellar, a stone half-vault 214 metres long, and explains how the master affineurs bring out the flavour of each wheel. The Lacuzon gallery, cut by hand into the mountain, keeps the long-aged wheels cool and damp all year.

Tickets

The standard cellar tour costs €11.80 for adults, €7.20 for ages 7 to 16, €5.90 for visitors with reduced mobility, and nothing for under 7s. A family pack for two adults and up to three children is €35. Tickets are neither exchangeable nor refundable. Arrive 15 minutes before your slot.
