Yverdon-les-Bains sits at the southern tip of Lake Neuchâtel, a small city that has been a spa town since Roman times. The thermal baths are still the main draw — the Centre Thermal is fed by sulphurous springs at 29°C — but Yverdon has more to offer than hot water.
The 13th-century Savoy castle on Place Pestalozzi now houses the town museum, and the old town around it is pleasant for a stroll. The real surprise is the Maison d'Ailleurs, a museum of science fiction and utopia that is unique in Europe, with a collection ranging from Jules Verne first editions to contemporary speculative art. North of the centre, the Menhirs de Clendy — a 6,500-year-old neolithic alignment — stand on the lakeshore, where the calm waters of Lake Neuchâtel are good for swimming in summer. Yverdon makes a relaxed base for exploring the Jura foothills and the northern Vaud countryside.
