The sky
Kosmos sits under some of the darkest skies in the U.S. In April 2026 it became Colorado's first DarkSky Approved Lodging property — a certification for how the whole property is lit, so the sky stays dark for everyone under it.
Tonight over Kosmos
Darkest nights fall around the new moon. Sky reports and telescope nights go out in The Dark Sky Journal.

A night at Kosmos
You arrive in daylight. The rest of the night is built around the sky.
Check in, lose the road behind you, and watch the Sangre de Cristos turn gold from your villa.
Every villa has its own telescope. Set it up outside before the last light goes.
An astronomer walks you through what is overhead — planets, nebulae, and in season the core of the Milky Way.
Soak in the private indoor jacuzzi, then fall asleep inside the dome with the sky still overhead.
Stay
Three private Stargazing Villas are open now. The Galaxy Villa and the Kosmos Suites are what we’re building next.
A two-story villa with uninterrupted views of the Sangre de Cristo Mountains, part of what we’re building next.
Hempcrete suites with a private stargazing terrace, a shared lounge and breakfast table. Waitlist members book first.
Book direct and a dedicated staff member is reachable by call or text at any hour of your stay.
Stargazing tours & astrophotography
Guided tours are open to visitors as well as villa guests — the same Bortle Class 2 sky, led by certified astronomers.
Guided
Three tour packages from $89. Planets, nebulae and the Milky Way through the resort’s telescopes, with an astronomer to explain what you’re looking at.
Hands-on
Workshop nights with Colorado Astrophotography — bring your camera and leave with the Milky Way on it. Dates are announced in The Dark Sky Journal first.
Guests say
Read what guests say about the sky, the telescopes and the team — on Google, where we can’t edit a word of it.
Featured guest reviews go here — three real Google reviews, name and month, chosen for the sky, the telescope and the staff.
Getting here
Kosmos is in the San Luis Valley — 25 minutes from Alamosa and 30 minutes from Great Sand Dunes National Park. Wild mustangs roam the valley beneath the snowcapped Sangre de Cristo Mountains, and the nearest town lights are far enough away to keep the sky dark.
Kosmos Stargazing Resort
Built for the dark
A self-sufficient retreat on a 40-acre parcel, adjacent to 700 acres of protected conservation land.
Villas built with sustainable hemplime and geodesic domes that open the room to the sky.
DarkSky Approved lighting keeps the property dark, so the stars stay bright for guests and for the valley.
The Kosmos journey
A concept takes shape on 40 acres in the San Luis Valley, adjacent to 700 acres of protected conservation land.
The first guests check in to the Stargazing Villas.
Kosmos becomes Colorado’s first DarkSky Approved Lodging property.
Today three Stargazing Villas are open, with a fourth villa and the Welcome & Astro Lounge under construction.
Before you book
