Thanks for your question, there are two hotel spas which outside guests can enter at a charge, the Piolets Park & Spa and the Sport hermitage spa. Both are very good quality, but are reasonably small.
In Canillo (10 mins by bus) there is a sports centre which can be accessed by public bus with a swimming pool and an ice rink.
In Andorra la Vella (25 mins by bus), there is Caldea - Southern Europe's largest indoor thermal spa and well worth a visit. It's huge with lots of different wellness areas. There is also some great shopping in the capital to pass the time as well.

Spa & Leisure facilities in Soldeu
dermot
Hi. Planning to travel to Soldeu with family in January. Is there any public spa, pool, leisure centre in Soldeu that you can use - or can you pay and use such facilities in one of the hotels? One of our family not too interested in skiing all the time and wants to relax in pool/spa area some of the time. Thank you.
