Even before the age of the railway, the Loire Valley drew vacationers from far afield, so there are hundreds of hotels of all types. At the higher end are sumptuous, stylishly converted châteaux, but even these are not as pricey as you might think. Note that most of these are in small villages, and that upscale hotels are in short supply in the major towns. At the lower end is a wide choice of gîtes, bed-and-breakfasts, and small, traditional inns, usually offering terrific value for the money. The Loire Valley is a popular destination, so make reservations well in advance—in July and August, this is essential (and we're talking weeks in advance, not days).
Be aware that from November through Easter, many properties are closed.
