Colorado Official State Vacation Guide - 2025

Colorado’s bluebird skies are beloved by just about anyone who finds themself outside during daylight hours. But when night falls, those clear days turn into dark, cloudless nights with nothing obscuring crisp constellations, rocketing meteors and glowing planets. It’s no coincidence that our state has some of the best stargazing in the country — its alpine setting creates the perfect conditions for unforgettable evening views.

In fact, in recent years, 17 areas throughout Colorado were designated as Dark Sky Places by DarkSky International. Let’s dive into what makes those spots — and so many others throughout the state — perfect for unhindered vistas of the Milky Way. Gazing skyward at a high altitude increases your limited magnitude — the faintest object visible with the naked eye — so you can see stars that are farther out in the galaxy. And as you go up in elevation, you’ll likely start to see more and more clusters appear.

Since mountainous areas get you that much closer to the skies above, you can simply unzip the tent, step outside and observe the cosmos in their full magnificence. Bordered by the vast open spaces of western Colorado, Black Canyon of the Gunnison National Park near Montrose has always been a phenomenal place to see the stars. The Black Canyon Astronomical Society and other stargazing groups conduct nighttime programs throughout the year, with experienced astronomers and astro-photographers on hand to assist visitors in the darkness.

Light pollution is the biggest enemy of proper stargazing. The closer you steer to cities, the less twinkling you see above. Higher-population areas typically rest within the “light dome,” where street lights, glowing signage and other luminaries prevent us from seeing the vast expanses of space. Here, dark places are easy to find for a quick weekend away in the mountains, where the soaring peaks play their part to block the lights from urban areas. Towns like Westcliffe and Silver Cliff keep the lights off to support nearby Smokey Jack Observatory, where one of Colorado’s most powerful telescopes magnifies the sky’s celestial show. Classes and stargazing events welcome the community and visitors.

But you don’t need a telescope to get started here — simply head 20 to 30 minutes beyond the city limits of your favorite mountain town, hang a hammock at a campsite and stare for hours at the untouched beauty of space. Late summer to early autumn is the best time to make the trip to towns like Pagosa Springs, when the Milky Way is the most visible. The archaeological sites of the Chaco culture have remained largely unchanged for 1,000 years at nearby Chimney Rock National Monument. There, ancestral wisdom and modern telescopic technology meet with unique Night Sky Archaeoastronomy Programs, where you can learn how the Chaco people used the stars for navigation, timekeeping and spiritual guidance. Our less-populated lower elevations have their advantages, too. Jackson Lake State Park in northeastern Colorado is one of the most scenic places to watch the Colorado sky. It was named an International Dark Sky Park in 2020, making it the first Colorado State Park to hold the coveted designation. With its large, glassy surface, the lake acts as the perfect mirror for the constellations. Known as “the oasis in the plains,” the lake’s peaceful evenings, sandy beaches and breathtaking view of the stars are definitely a sight worth seeing.

Protect the Night
