Hey there! I have not been on the Camino during the winter, when it is a little less crowded, but I went this summer. I was not alone, but with my friend, also a girl, and we were both 18 years old. I'll tell you I have never felt safer in my life! I felt one hundred times safer everyday on the Camino then I do walking down the street on a daily basis back in the US at college. You truly have nothing to worry about! We camped out in parks in bigger cities and I ditched using my money belt after the first week (probably not a good decision, but still) and never had any problems, NEVER felt unsafe in the least. My friend and I were actually just talking about that yesterday--I miss the feeling of safety and security. You will have the time of your life!
