When wandering around in Guild Wars 2, a player can stumble upon a vista. Vistas locations can be activated in order to start a short cutscene that gives the player a sweeping aerial view of the new area they found.
In a short video published today, you can watch one of the cutscenes for the snowy vista, Hoelbrak. As the player activates the flapping map icon, the camera pans out and moves so you can view the new area. Vista activation also contributes toward map completion.
