START HERE / NIGHT RIDE 00
Start with the ground. Then look up.
Choose the part of Colorado you actually want to reach first, then decide how dark you want the sky. The Night Ride will narrow the guide from there.
LAND + SKY / PREAMBLE
Respect the land.
Share the sky.
ColoradoStargazingTrail.com pays respect to the Indigenous peoples and sovereign Tribal Nations whose homelands include what is now Colorado, including Ute, Cheyenne, Arapaho and Puebloan peoples. Those relationships with land and sovereignty are living and continuing.
Now look up. The borders on the ground sit beneath one continuous sky. People everywhere have used that sky for navigation, seasons, science, ceremony, memory and story. The constellations change with culture; the stars keep crossing every line on the map.
How this guide approaches land + sky ↗
FIELD MANUAL / BEFORE IGNITION
Four things can change
the whole night.
Cloud. Smoke. Road. Moon. Check those four before every trip and stop surprises from ruining your trip.
Moon
A new Moon reveals fainter sky. A bright Moon can turn dunes, snow and canyon walls into the show. Pick the Moon that matches the night you want.

Look at the hours you will actually be outside. A clear window from 10 to midnight can matter more than the icon for the whole day.
National Weather ServiceSmoke
The sky can be technically clear and still look washed out. Wildfire smoke is worth checking before a long drive for faint stars.
AirNow fire + smoke mapRoad
A mountain pass at midnight is not the same road it was at lunch. Check closures, snow and the way back before dark.
Colorado road conditionsFIRST BRANCH / GEOGRAPHY
Where do you want to ride tonight?
Choose the road first. These regions overlap on purpose. Denver is the shared western/eastern hinge for several of them, while places like Alamosa, Steamboat Springs, Gunnison and Durango become the more useful local hubs farther out.
STATEWIDE MAP / GUIDE GEOGRAPHY
Colorado, all at once.
Every mapped guide stop in Colorado sits on the same USGS/Census geography. The colored washes are curated guide travel zones; dashed lines show the five editorial loop sequences. Featured guided programs are marked separately from general guide stops.

Central Mountains & High Country
Denver is the natural eastern gateway, then the road splits into Summit County, the Arkansas Valley and higher mountain country. State Forest State Park forms a deliberate northern overlap with the Front Range and Northwest regions.
Eastern & Southeast Plains
Denver is the western gateway and overlap for this region, where the city gives way to prairie. From there the road splits northeast toward Pawnee and Jackson Lake or southeast toward Pueblo, Lamar, Kim and Comanche.
Denver, Front Range & Pikes Peak
The long Front Range spine: Fort Collins, Boulder and Denver in the north; Colorado Springs and Pueblo through the middle; Trinidad at the southern edge, with foothill and observatory stops branching off the I-25 corridor.
Northwest Canyon Country
Steamboat Springs is the main eastern gateway to this region, with State Forest State Park intentionally overlapping from North Park. From there the road runs west and northwest into reservoirs, high basins, Craig and Dinosaur country without pulling the map back toward the Front Range cities.
San Luis Valley & Sangre de Cristo
Colorado Springs and Pueblo form the northern approach, with Browns Canyon as an intentional overlap into the Arkansas Valley. Alamosa becomes the real hub once the road crosses into the valley and the sky opens around the dunes, hot springs and Sangres.
Southwest & Four Corners
This region does not need to bend back toward Denver. Durango is the natural launch, with Cortez and Pagosa Springs taking over for the western and eastern sides of the Four Corners road.
Western Slope & Gunnison Country
Breckenridge is the eastern edge of this region. From there the useful hubs move west to Gunnison, Montrose, Grand Junction and the Roaring Fork Valley, with the Lake City high country holding some of the darkest mountain sky in the guide.
SECOND BRANCH / DARKNESS
How dark do you want the sky?
Pick the Bortle class that matches the night you want. Lower numbers mean darker skies. Choosing a level jumps you straight to the Colorado stops currently rated at that level.
Excellent dark-sky site
The darkest end of the guide. Milky Way structure can dominate the sky and faint detail becomes much easier to see.
SHOW ME BORTLE 1 LOCATIONS ↗BORTLE CLASS / 13 STOPS2Typical truly dark site
Very dark rural sky with strong Milky Way structure and only modest distant light domes.
SHOW ME BORTLE 2 LOCATIONS ↗BORTLE CLASS / 28 STOPS3Rural sky
A dark rural observing sky with some distant glow but plenty of contrast left for deep-sky observing.
SHOW ME BORTLE 3 LOCATIONS ↗BORTLE CLASS / 15 STOPS4Rural / suburban transition
Still a useful stargazing sky, with more obvious light domes and less contrast on faint diffuse objects.
SHOW ME BORTLE 4 LOCATIONS ↗BORTLE CLASS / 5 STOPS5Suburban sky
Skyglow is obvious, but brighter clusters, nebulae, planets and the Moon remain strong targets.
SHOW ME BORTLE 5 LOCATIONS ↗BORTLE CLASS / 1 STOP6Bright suburban sky
Skyglow dominates much of the view and faint galaxies and nebulae become substantially harder.
SHOW ME BORTLE 6 LOCATIONS ↗BORTLE CLASS / 1 STOP7Suburban / urban transition
The Milky Way is generally gone and the night shifts toward brighter stars, planets, double stars and the Moon.
SHOW ME BORTLE 7 LOCATIONS ↗BORTLE CLASS / 1 STOP8City sky
Strong urban glow leaves mainly bright stars, planets and the Moon as easy naked-eye targets.
SHOW ME BORTLE 8 LOCATIONS ↗Lower number means darker sky. These are quick planning estimates or field/source-supported ratings for the guide location, not a guarantee for an entire park or town. See every location by Bortle class ↗ · Read the Bortle scale ↗
