A couple of times now I have walked a stretch of the Camino de Santiago (each time it was just a small bit near the end; sadly don't have the time off to do a full route which can take a month or longer). I find the simplicity of it super rewarding and enjoyable compared to my busy life back home. Just, for the most part, miles and miles of peaceful countryside.

It's kind of the opposite of what is described in the article, where the author is using his time off to improve his knowledge in other areas. Personally, I find that back home I am constantly thinking, both at work and in my time off, so much so that I forget what the end goal of all that thinking actually is. So doing these long walks helps me take a break from that and put it in perspective. No laptop, as little smartphone use as possible, I will maybe read a book or two in the evenings but nothing too heavy, etc.

As an aside, I am in a non-tech field, and programming is my hobby (and nothing like my day job). I enjoy it and I think it helps me stay sharp, but it has its drawbacks as a hobby. Being a solo hobby, and not one that many people in my field are into, it's not really something I can easily bond with others over (unlike, say, golf or chess). And sometimes it can be the opposite of relaxing when you encounter a bug that you can't seem to diagnose or fix.
