ROCKY MOUNTAIN NATIONAL PARK

Welcome to Rocky Mountain National Park, a stunning expanse of alpine landscapes, soaring peaks, and pristine lakes in northern Colorado. The park is a crown jewel of the American West, drawing more than 4.5 million visitors annually with its sweeping vistas, diverse ecosystems, and endless recreational opportunities.

From lush montane valleys to windswept tundra, Rocky Mountain National Park showcases the dramatic elevation range of the Rockies — with peaks topping out above 14,000 feet. It is a place to hike, climb, watch wildlife, and simply breathe in the mountain air.

My personal experience

The first time I drove Trail Ridge Road, John Denver’s “Rocky Mountain High” was stuck in my head — and perhaps that’s unavoidable. Ever since I was a child visiting the Austrian Alps with my parents, I’ve thought of the mountains as my quiet refuge. Rocky Mountain National Park feels like that kind of place, though in peak season it is far from quiet! But if the mountains are calling, I must go. Memorial Day through mid-October is your chance to drive Trail Ridge Road, a 48-mile highway crossing the park east to west. It is the highest continuous paved road in the United States, cresting at 12,183 feet. Even in July, I found snow at the Alpine Visitor Center and weather that shifted by the minute. But the panoramic views were unforgettable — and so was the wildlife. On that first trip I saw bull elk, bighorn sheep, deer, and even a coyote and a marmot. I might have seen an eagle fly – Rocky Mountain High – and…. back in your head.

Another visit over Thanksgiving weekend was different entirely. My wife and I hiked to Bear Lake, which was frozen solid. Some brave souls were walking across the ice — we were not! Instead, we kept to the trail and were rewarded with a moose sighting as the daylight faded.

If it’s your first visit in summer, I recommend driving Trail Ridge Road for the full alpine experience, then picking a hiking trail suited to your fitness level. With over 355 miles of trails, there is truly something for everyone. Remember, though: park elevations range from 7,500 to 12,000+ feet. Even fit visitors from lower elevations — “flatlanders” — may feel the effects of altitude. Drink plenty of water and take it slow.

General Aviation


General aviation pilots have multiple options to get to Rocky Mountain National Park. Please keep in mind that you are flying in the mountains. Weather can change rapidly and density altitude is always a factor.

East Entrance (Estes Park) – All airports sit at about 5,000 foot elevation.

  • Boulder Municipal (KBDU): The airport has two 4100 ft. parallel runways and offers full service FBO with 100LL and Jet-A available. It’s a 1h 15 min drive to Estes Park.
  • Vance Brand (KLMP): has one 4,799 ft. runway and offers full service FBO. It’s about an hour to get to the park
  • Northern Colorado Regional (KFNL): Need a longer runway? How does 8,500 ft. in KFNL sound? The airport offers full service FBO and it should take you about 1.5 hours to get to the east entrance of the park

West Entrance (Grand Lake)

  • Granby-Grand County (KGNB): Ain’t to airport high enough? How about 8,207 ft? GNB has one 5000 ft. runway and offers 100LL and Jet-A. The airport is about 20 miles from the Grand Lake entrance.

Do you want to fly with the big dogs? Consider Denver International (KDEN), about 75 miles south east of the Estes Park entrance.

Whether you’re watching elk bugle in autumn, snowshoeing past frozen lakes, or summiting a rugged 14,000-foot peak, the park delivers a true mountain adventure. For me, the Rockies are both exhilarating and grounding — a reminder that the mountains really are calling, and we must go.
