Of course the Camino has changed, and many of those changes are not to my liking. The
Camino Frances, at least at certain times and segments, seems too "canned" (packaged) and too social for me. Theme parks are great fun, but in small doses! We can lament the changes, but why should we get to decide that things should be preserved at the point that
we think was perfect, and restrict access for others. Life doesn't work that way.
Certainly there are logistical and ecological considerations that can be improved, and I hope they are.
Is it possible that the above two statements illustrate a conundrum? Like many of us, you want adventurousness and empty spaces but you want security and shorter distances between lodgings. I don't know what you mean by "big distances" but I am in my mid-70s and have feet that complain, but I am able to work out plans for other routes, so that I typically don't walk over 25 km, and I always have a Plan B for the few stages that require 30 km. It definitely takes more preparation/planning and a willingness to adjust while on the ground, since the details are not handed out on silver platters. Sometimes I find myself outside my comfort zone, but that is where the adventure lies. Each year, when I head to Spain, I ask myself why I am not satisfied with more conventional vacations.
It wouldn't be adventurous to do the same thing over and over. So, if you are seeking more adventure, challenge, or empty spaces, you will have to go after it.
