I enjoy walking home in spring. I enjoy walking outside. I enjoy that lots of other people are walking outside. I enjoy the sunshine and the flowers. I enjoy that my walking is useful instead of recreational. I am walking to go some place. And yes, it is enjoyable, at least part of the time, while I am providing my own “transportation”. But I never go for a walk to “go for a walk”. That just seems like an inefficient use of my resources.
