My trip alone the "Camino de Santiago" was very special. I went there alone because I thought it was the best way to do it. There are many people from different countries.
While you're doing the route, talk to everyone. There are people from North America, Canada, Japan, etc.
I recommend doing this trip without a company because it is a trip to the interior of the person, and it is good to go alone and meet the people that you are tripping along the way.
