The open world map of Forza Horizon 4 is massive so it’s understanable that you may want to fast travel occasionally. There is only one way to fast travel in Forza Horizon 4 and it done through the in-game map. Pulling up the map at any time is easy by pressing the View button (Back Button) on the Xbox One Controller.
Once you got the map open the places you can fast travel will show you the option to do so either on the icon when hovering over them or at the bottom of the screen. To fast travel you will always press the X button to do so. If you can fast travel it will cost you a certain amount of CR to get there.
Places that you can fast travel to include the Horizon festival (Big H) on Map. You can also fast travel to current home or other homes that you have purchased for an amount that is determined by how much progress you have made in the game.
The amount it costs to fast travel is dependent on how many fast travel billboards that you smash through in the game. Smash more boards and you will pay far less to fast travel to these locations. Fast travel billboards are the purple icons on the map with a lightning bolt on them.
