If you take a daylight train ride in the spring, via Rocky Mountaineer, you may see a few bears, emerging after their winter hibernation. This is also a good time to see birds nesting, as the hardwood trees are just starting to show their leaves. In the summer, the trees and vegetation are lush and green and you will see more wildlife. If you travel during the fall, you won't see the leaves colored, to the same extent as they are in the U.S. in New England. That is because evergreens dominate the area.
