I know Hemingway liked Walton, and I've tried to read the book once or twice, but I just couldn't care less about fishing. I also cannot recommend Goethe's Italian Journey, but then you like him much more than I do. As far as Wang Wei goes though, I concur with your opinion.
I'd recommend Thoreau's Walden, Hemingway's Big Two Hearted River, Faulkner's The Bear, or London's The Call of the Wild.
