The Château-Arnoux Castle Park is a remarkable 12-hectare natural area, classified as a "natural site and monument" since 1951. It surrounds the Renaissance castle which currently houses the town hall.
The park is famous for its bridle path connecting the Font Robert farm to the castle. It features a blend of exotic species alongside Mediterranean and mountain vegetation. The 1.3 km Park Trail (approx. 20 minutes) offers a chance to discover the local flora and fauna. An explanatory brochure is available at the tourist office.
The Castle, built between 1510 and 1530, features a listed spiral staircase and Renaissance decorations (gargoyles, mullioned windows). Guided tours are available upon request through the heritage association.
