I've been reading on the web about shuttle services in Glacier National Park. How does it work? Does it start from East Glacier station? What does it cost? How often do they run?
The park site on nps.gov can give you up-to-date information. The shuttles run both directions on Going to the Sun Road. They are free, with designated stops, you can get off at any stop and get back on another one providing there's a seat. Definitely more relaxing than driving that road. Also there's at least one privately operated shuttle-tour thing but I don't know how much it costs. over 5 years ago
