It is extremely rare for us to cancel a trip due to weather. However, if the National Park Service completely closes the Denali Park Road for any reason, we cannot operate the trip. If the Denali Park Road is partially closed, we will travel as far as we are permitted. Our Denali Park Road trip covers 66-miles traveling through a number of mountain passes, and the weather can be quite different than the east entrance to the Park. We recommend booking the full-day trip for any day that fits within your schedule, regardless of the weather forecast.
