Spain is a lovely country to visit---I have been there at least twenty times in the last ten years. But the hiking there is a bit more civilized than we are used to in our wilderness areas. Be prepared for small towns, sheep, country roads, and even larger evidence of cities on a lot of the trails.

Makes the hiking considerably more delicious!
