I am a first time pilgrim interested in hiking the Camino del Norte. As a rugged 63 year old from Berkeley California I am confident I can take on the walking, but I am concerned about my husband, also 63, who can sometimes have knee and ankle problems on rugged terrain. 1) How steep and rugged is the terrain? 2) Is it possible that one some days my husband sometimes take buses and meet me at the refugio in the evening?
