So I was thinking eventually in a year or 2, I wouldn't mind doing an Amtrak trip to Whitefish, and of course from there go to Glacier National Park. Hadn't decided if I also should try to visit nearby Waterton Lakes National Park in Alberta(and bring my passport), or not. I was thinking Whitefish over Essex, since it seems to have more local amenities(motels/hotels, car rental places, etc) vs. Essex(not sure if there's anything there, except the Isaac Walton Inn). I know I also could go from East Glacier Village into the national park, but am still leaning towards Whitefish. Anyway, I have some dumb questions to ask(forgive me, lol!), based on early Googling and various message board threads I've read. Are there any free shuttles within this national park(i.e. Zion National Park), or is it better to rent a car and drive to the portions of Glacier National Park I was interested in? I was worried at first the best option would be to rent a car after arriving in Whitefish or East Glacier(though probably I'll do Whitefish), but I do wonder how extensive the shuttle system is within this park. And in the opinion of those who've gone here, what would be the best months to visit this park? It does seem like from road closures if you go in the winter, that probably the best time to visit would be sometime in the mid-late spring or early-mid fall. And perhaps, that you run into slightly less crowds vs. summer. But who knows? Back to the rental car question(I have a license, but just haven't actually rented a car before), do any of the rental car companies allow one to cross the border to Alberta(just for Waterton Lakes) and back? I assume they would, but won't be surprised if they charge an extra fee if you want to do that. Knowing how rental car companies(from what I've researched) can nickel and dime you, over certain minor things. Also, any local things/points of interest worth stopping at in this immediate area surrounding Whitefish(and etc. with the towns nearby) besides Glacier National Park? And of course, any recommended nearby places to eat that are decent would be nice to hear about. I was still trying to do Tripadvisor/Yelp/Google research, to figure out what I can on this area. My bigger question mark I want to find out, is if the national park has any shuttles to get to various parts of this park. Or is it only that a few of the nearby motels/hotels, have shuttles that'll get you to various parts of this park? Thanks to someone, who can clarify my confusion on that.
