Rocky Mountain National Park is one of the best national parks for viewing wildlife, particularly in spring when animals tend to stick to the valley floors and fall for the mating rut. The park is home to 67 mammals including moose, elk, bighorn sheep and marmots, and you'll want to head out in the cooler early mornings and late evening hours for your best chance to spot wildlife.
