Getting there & away
Chaumont-sur-Loire is on the Loire’s south bank 17km southwest of Blois and 20km northeast of Amboise. The path leading through the park to the chateau starts at the intersection of rue Maréchal Leclerc (the D751) and rue du Village Neuf. To get to the parking lot behind the chateau, drive up rue du Village Neuf, take the first right and follow the signs to the stade (stadium).
Onzain, an easily walkable 2km (across the Loire) from Chaumont, is on the Orléans–Tours rail line. Frequent trains go to Blois (€2.90, 10 minutes, 10 to 20 daily) and Tours (€6.90, 35 minutes, 11 to 22 daily).
By bicycle, the sleepy back roads on the southern bank of the river are a tranquil option.
