We have spent several summers in Andorra and have slowly found more and more to do. A car is essential really as although public transport exists it is quite sparse and difficult to work out what goes where and when.
Horse Riding - locally in Soldeu Mountain Biking - locally in Soldeu Quadbiking - quads can be hired locally in Soldeu Grand Valira Summer - things to do up the mountain Andorra Hash House Harriers
Swimming - locally at various hotels in Soldeu which can normally be used on payment of a charge. eg Piolets Park and The Sport Hotel. In Encamp there is both a large indoor pool and a nice outdoor 'Lido' style pool, at different sites. Caldea - a very large indoor Spa in La Vella
