About Rocky Mountain NP
Rocky Mountain National Park sits above 8,000 feet along Colorado's Front Range, and while growth in nearby towns has brought some light pollution, the park's high alpine terrain still delivers some of the state's better accessible night skies. Rangers run seasonal Astronomy in the Park events.
What you can see in the sky
Milky Way over alpine meadows and peaks, with ranger-led Astronomy in the Park telescope nights held on select summer evenings.
Best time of year
Late summer into fall for the clearest Milky Way views before winter snow closes higher elevations.
Why this site is worth the drive
High elevation (8,000+ ft) gives thinner, cleaner air for viewing
Seasonal Astronomy in the Park ranger programs with telescopes
Trail Ridge Road, when open, reaches over 12,000 feet for exceptional dark, high-altitude views
