In Escaldes, the Caldea Spa Complex is Europe's largest. Looking like some futuristic cathedral, it's a wonderful place for some soothing relaxation after exertions in the mountains. Fed by hot springs, its heart is a 600-sq-metre lagoon kept at a constant 32°C. A series of other pools, plus Turkish baths, saunas, spas and hydromassage, are all included in the three-hour entrance ticket.

You can sign on for a whole range of extras, including 'Turkish exfoliation', 'body scrub' and the enticing 'full hand care'. Caldea is a 10-minute walk upstream from Plaça de la Rotonda.
