Renting a car from the airport would probably be the easiest option to get around the area, but you can look into shuttles to and from a hotel if you book a room at one of the hotel options in West Glacier. We will be arriving to our VRBO Wednesday September 4th-Monday September 9th. Feel free to stay longer than we are, we just want to let you know our plan.
Look for places in Colombia Falls, Hungry Horse, Coram, and West Glacier areas. Colombia Falls is the furthest of these options and is about 20 minutes from Glacier. You can book outside these areas but it may be a farther drive. I’ve found better, more affordable options on Vrbo but both have options.
