An adventure is something exciting that happens to someone. An adventure can be a made-up story, or it can be something that happens in real life.

People often like stories about a person or a group of people who go off and have an adventure. There is often some danger in the story. Enid Blyton and Edgar Rice Burroughs wrote stories about people who have exciting adventures. Harry Potter has lots of adventures: he meets strange people and gets into lots of dangerous situations.
