The Forêt de Tronçais covers around 11,000 hectares in the west of the Allier, most of it oak. Its management goes back to Colbert's order of 1670, when it was kept for the timber of the French navy. Today its oak also goes into wine barrels.
The Étang de Saint-Bonnet, about 45 hectares of water at Saint-Bonnet-Tronçais, is the usual place to begin, with paths around it and through the trees.
