Skiing and Hiking
Arinsal has a ski school, which offers tuition for all levels in skiing and snowboarding.
During the summer, there are lots of hiking groups who come to Andorra. You'd need to be really fit to do it!! If you book through a travel agent, a lot of the equipment could be included in the price, but check first!!
