With a little advance planning, one of the easiest châteaux to visit is Château Lanessan. Its daily hour-long guided tours take in the neoclassical château, its English-style gardens with magnificent 19th-century greenhouse, the stables built in 1880 in the shape of a horseshoe with marble feed troughs, the pine-panelled tack room and a horse museum with several 19th-century horse-drawn carriages. Tours end with wine tasting. Advance reservations, at least one day before, are obligatory.
