How far in advance should one purchase a park pass, vehicle reservation and a pass to drive the Going to the Sun road? I haven’t been in a NP in a few years but it’s time to add in some US sights! All these pass and reservation requirements are new to me. The current plan is to visit in August 2025. I know I need to get cracking on accommodations. We’ll likely travel up to the Banff area as well.
Many thanks!
