Roll out of Montegrotto Terme and let the ride unfold: through the Parco dei Colli Euganei nature reserve, along the Canale Bisatto canal and past the Castello di San Martino della Vaneza castle. The Bacchiglione river leads you on to La Specola and the Castello Carrarese, both castles, before the Canale Scaricatore canal and Villa Giusti manor point you homeward. All 82.3 km are paved, with 504 m of climbing along the way, and the loop closes back where it began.
