Rocky Mountain National Park in Colorado

TripSavvy / Christopher Larson


Rocky Mountain National Park may be the most spectacular park in the United States. It's conveniently located near Denver (only 2 hours away) and is full of things to do and beautiful things to see. With massive mountains as a backdrop, tundras of rolling wildflowers, and Alpine lakes, this park is truly stunning.


Rocky Mountain National Park was established on January 26, 1915. Wilderness designation was given on December 22, 1980, and the park was designated a Biosphere Reserve in 1976.

When to Visit

The park is open year-round but if you want to avoid crowds don't visit between mid-June and mid-August, when the park is busiest. The months of May and June offer great opportunities to view wildflowers. The fall is a beautiful time to visit, especially on sunny September days. The land turns red and gold and offers unbelievable fall foliage viewing. For those seeking winter activities, visit the park for snowshoeing and skiing.
