Dear friends, We are walking just a portion of the route and will end our five day hike in Tomar. My biggest concern is access to clean water. Is this a problem? I hate to buy plastic bottles. My group of four is very excited about the trip. I hike but I do not generally walk 12 miles a day. I am hoping that the route is fairly easy but, just in case, I know the train stops and times. Thanks for your help. Laurel from Oregon.
