<span> Since Walden is based on the author's personal experience which he decided to share, this book can be considered as a narrative essay. In his book,  Henry David Thoreau represents all his life experiences and realizations that came up to him when he was living in natural surroundings. In a narrative essay, the writer tells a story about a real-life experience, so I bet that Walden belongs to this kind.</span>
