Just curious, for those who have completed this Camino, are the many streams/ fresh water sources along the route? I want to know if it’s worth taking my mini water filter. Also, as I’m going to be taking my tent and camping for the majority of the Camino, (staying in a hostel/ hotel maybe once a week), I want to know if there will be streams to wash my clothes in or if I will have to use seawater. Thank you!
