A type of writing in which the author discusses places they have been and their travel experiences. Travel writing can be used to document trips or to offer advice to others who might want to visit these places themselves. The term was first used by Henry David Thoreau in his book Cape Cod: A History of Its Islands (1869). He described it as "the writing of travel, but not of geography; of anecdote, but not of science." In modern usage, the term applies to any written account of a trip or journey. Thoreau also described walking as one of the perfect activities for understanding nature and gaining new knowledge about the world. He said: "Walking is one of the best remedies for the blues. My own mental health depends greatly on my daily walks. I feel refreshed after a walk, ready to face the challenges of the day." Walking helps people see and understand things around them more clearly and gives them time to think and compose their ideas before starting work on them.
