For various reasons we, as first time walkers, have decided to walk this stretch of the Camino. The biggest worry I have is the weather at the end of April. Can we be assured of rain and mud for the whole week? Secondly, would those in the know recommend a good poncho or rain jacket? Thirdly, the shoes...should they be waterproof if it's wet and muddy? Does "waterproof" really mean that the shoes will stay dry over the distance?
