This loop, which is difficult because of its altitude difference of 20 m, allows you to discover the village of Carlux and Simeyrols in both a sporting and cultural way? The Prats-de-Carlux church, the Church of Saint-Côme et Damien, and the Château de Carlux are all worth a visit. The latter is open to visitors free of charge... it would be a shame not to take advantage!
