Private Events at Kosmos

Host your next gathering under some of the darkest, clearest skies in the country. Kosmos Stargazing Resort & Spa sits just outside Great Sand Dunes National Park & Preserve, in a DarkSky Approved setting in Colorado's San Luis Valley — a private, unforgettable backdrop for the people who matter most to you or your organization.

What You Can Host Here

• Full property buyouts — reserve the villas and grounds exclusively for your group.
• Corporate retreats & offsites — a distraction-free setting for leadership meetings, team retreats, and incentive trips.
• Milestone celebrations — weddings, anniversaries, reunions, and birthdays under a genuinely dark sky.
• Private stargazing & astrophotography sessions — a guided group experience built around your date and party size.

What's Included

Every private event is built around your group's size and goals. Our team can coordinate villa accommodations, guided stargazing led by our on-site astronomy staff, and access to the property's dark-sky infrastructure — all set against skies certified by DarkSky International.
