I've backpacked all over the world by myself, but last time I flew out I just kind of got idk, bored of it? There's only so much to do if you're by yourself in a place where you don't know anyone or speak the language very well (if at all). You take walks, you go to museums, you eat the local foods and go out clubbing at night, see if you can't get laid, maybe go to the beach if there is one. And then you can do some hiking if you're in the wilderness.
