FYI - New this year!
You have to have a park pass AND a Reservation/Ticket to get in and drive the Going to the Sun Highway.
Glacier National Park is instituting an online reservation system (ticketed entry) for the Going-to-the-Sun Road corridor between the park’s West and St. Mary Entrances from May 28 to September 6, 2021.

At least you can still get in without taking a shuttle as in Zion.
