Roll out of Busca for a loop that keeps four castles in the picture: Castello Reynaudi and Castello Rosso come first, then Castello di Monasterolo di Savigliano and Castello di Solere. Between them the route follows the Varaita, the Mellea and the Torrente Maira, so the water keeps you company. The surface is fully paved, with 263 m of climbing spread across the ride. Back to Busca where it began.
