The valley crossed by the Topino river and the slopes of Mt. Subasio form the splendid natural backdrop for the town of Valtopina, a territory rich in natural beauties that allow wonderful excursions in the middle of unspoiled nature. Among the numerous castles, which can be reached by hiking, we recommend the Castello del Poggio, Gallano, Santa Cristina, Pasano and Serra, still today evoking the enchantment of the Middle Ages.
