I am flying into Bozeman and spending a week in Glacier and a week in YS in July. I am starting with Glacier NP due to hotel reservations. I can begin in either East or West Glacier, but think I would rather end in West Glacier due to preferring those reservations at the end of the week, but can do that first and East Glacier last if need be. Most reservations are in the Many Glacier area.
I need to return from Glacier and enter the park in West Yellowstone to begin my YS adventure. What is the best routes to take to and from and what is the approximate times they would take? Is there a particular reason to prefer one route over another? Thanks for your help.
