Robert Louis Stevenson’s Thoughts on Walking – Walking Tours – A Night among the Pines – Forest Notes [EPUB ebook] 

It must not be imagined that a walking tour, as some would have us fancy, is merely a better or worse way of seeing the country. There are many ways of seeing landscape quite as good; and none more vivid, in spite of canting dilettanti, than from a railway train. But landscape on a walking tour is quite accessory. He who is indeed of the brotherhood does not voyage in quest of the picturesque, but of certain jolly humours-of the hope and spirit with which the march begins at morning, and the peace and spiritual repletion of the evening’s rest.
