Here's a video to help you plan your next bike adventure to Glacier National Park. I visited in June when Going to the Sun Road is open to hikers and bikers.
In this video I bike from West Glacier to the Loop, a midpoint on Going to the Sun Road. In the middle of the day I also went for a hike to Snyder Lake, and got lunch at Lake McDonald Lodge. Oh, and there were mountains. Tasty, delicious mountains.
Total distance: 52 miles biking, 9 miles hiking.
