fietsgids The River Loire Cycle Route

Guidebook to cycling the Loire, France's longest river, from its source in the Massif Central to the Atlantic. The 1061km route incorporates the popular, waymarked Loire à Vélo and takes in extinct volcanos, vineyards and châteaux. Predominantly downhill or flat, the route utilises mostly cycle paths and minor roads.

Seasons
The whole route can be cycled when the mountains near the source are snow free, usually April-October. Stages 7-26 can be cycled at any time of year, though April-October is the best period.
Centres
The route passes through Le-Puy-en-Velay, Roanne, Nevers, Orléans, Tours, Saumur, Angers, Nantes and St Nazaire.
Difficulty
Apart from a steep 1000m climb to reach the start and a few ascents and descents in the first six stages this is a straightforward route that is generally downhill or level. Mostly asphalt surfaces in good condition suitable for hybrid or touring cycles. Much of the route follows dedicated off-road cycle tracks, suitable for family cycling, though there are a few short sections where main roads are used.
Must See
Mont Gerbier de Jonc and the volcanic hills of the Ardèche, Le Puy-en-Velay, Charolais hills. After Nevers the route follows La Loire à Vélo, France's most popular cycleway, passing many of the royal châteaux (Chambord, Blois, Chaumont, Villandry, Amboise), vineyards (Sancerre, Touraine, Chinon, Saumur, Anjou, Muscadet), and historic cities (Orléans, Tours, Angers, Nantes) of the Loire Valley.
