Caldea Spa, Andorra la Vella

Southern Europe's largest thermal spa, a huge glass spire in the centre of Escaldes-Engordany, with indoor and outdoor lagoons of thermal water, Jacuzzis, saunas and hammams, and views of the mountains.

Andorra la Vella, the capital, is known for duty-free shopping. The old Casa de la Vall, Andorra's former parliament, is worth a visit. The Romanesque churches of the valleys, such as Sant Joan de Caselles, are lovely.
