The park is broken into two parts in America, with a third section in Canada. The western portion is the most visited, and it has more forest, waterfalls, and water. The East side is more rugged with jutting peaks, visible (melting!) glaciers, and lots of wildlife. Not knowing much, I booked a room at Many Glacier Hotel on the East Side.
There were tons of waterfalls with all the snow melt coming down they were at their full potential.
After 5 days we headed to the Canadian side of the park, Waterton. This time I stayed at the Prince of Wales hotels, another great railroad hotel with some really fun features, and a gorgeous view.
