Walking in the Vall de Boí is really well organised and most people will find enough to keep busy for 2/3 days
within the confines of the valley itself.
Visiting the Romanesque churches provides a series of mini
objectives and with bars and restaurants in all the villages there are also
plenty of places to stop and relax.
The paths themselves are wonderful. In
nearly all cases, they are based on the original inter settlement routes and are
as old as the villages themselves.
Designed for pack horses/ponies as well as pack people they are perfectly
graded and walking along them is a real pleasure.
Depending on how much time you spend in the churches (they are not that big) you can get around the valley in 9/10 hours. It's a challenge, but not quite as mad as it sounds as the paths are so
easy and such a pleasure stopping is a problem.
