Leisure centre of Iloa, Outdoor leisure center in Thiers, France

Leisure centre of Iloa is a 70-hectare outdoor recreation area in Thiers, built on the floodplain of the Dore between the river, the RD44 and the Clermont–Thiers–Boën railway. Its single-storey reception building has a dark hipped roof, deep eaves and tall glass doors. The site includes beaches, ponds and lawns, and most of it is protected by the Natura 2000 network.

A dam trial on the Dore near Pont-de-Pore failed when Michelin's rubber retention membrane lasted only through its inauguration, so Thiers dug the two-hectare Étang du Chambon instead. Gravel extraction from 1960 reshaped the riverbed and left about ten ponds. Construction on the Courty site ran in four annual phases from 1985 to 1988, cost 30,930,000 francs, and the base opened in 1989.

The center sits within a protected natural area and serves as a gathering place for outdoor recreation in the region. Visitors experience local landscapes and wildlife through day-long visits that connect them to the natural character of the Livradois-Forez park.

The site lies 7 km from Thiers town centre and 2 km from the Thiers-ouest exit of the A89; TUT bus line 2 serves its northern edge. Between June and September a free shuttle links the town centre to Iloa. The grounds are flat and explored on foot, with the Dore running through the site.

The grounds are part of a protected natural area across Europe and feature navigation courses that visitors can follow using special maps. These courses let individuals and groups explore the surroundings in an interactive way.
