Rocky Mountain National Park is located in the Front Range of the Rocky Mountains, in the north-central region of Colorado.With majestic mountains, tundra wildflowers, abundant wildlife, Trail Ridge Road (the highest paved road in the US), and over 350 miles of trails, Rocky Mountain National Park is spectacular! RMNP is home to a wide variety of wildlife. In the higher alpine areas, one can find yellow-bellied marmots and pikas. Larger mammals that inhabit the park include elk, bighorn sheep, black bears, mountain lions, mule deer, and moose. September, the sunniest month, is a wonderful time to visit: Elk move to lower elevations, and you can hear their mating bugles. The tundra turns crimson early in the month; aspens turn golden later and big blue sky is amazing.
