Season Passes include trail use and shuttle service on any day we are open during the 2015 Hiawatha season which is Memorial Day weekend through September 27. After purchasing your season pass and before hitting the trail, please go to the main lodge at Lookout Pass just off the I-90 on the Idaho Montana border, to get your picture ID taken and your pass issued to you. An adult pass for trail use without shuttle service is available for $29 at the Guest Service center in the main lodge.
