Because of that surge in popularity, Acadia National Park can be incredibly busy at the peak of summer tourism season. The demand has grown so rapidly, a reservation system was put into place for vehicles that want to traverse the Cadillac Summit Road from mid-May through mid-October.

The demand has also seen the admission price at Acadia National Park rise as well. Currently, it costs $35 for standard vehicles, $30 for motorcycles and $20 per person to enjoy a small slice of Maine's gorgeous outdoors.
