Sometimes people can get addicted to traveling. There is a term called dromomania, which describes an impulse to travel aimlessly. The Diagnostic and Statistical Manual of Mental Disorders added this issue to its definitions in 2000.
There is both a clinical and non-clinical use for this term. The clinical application refers to an uncontrollable need to walk or wander. The non-clinical application refers to anyone who has a frequent desire to travel or wanderlust.
