Weddings at KSS

__Micro Weddings | Elopements | Mountain Weddings_____

Why Choose KSS for Your Wedding

Nestled in the heart of the Rocky Mountains, Keystone Science School offers a naturally stunning backdrop for couples seeking an intimate and meaningful celebration. Our mountain campus is surrounded by towering peaks, peaceful forests, and wide-open skies — the perfect setting for a day that feels personal, beautiful, and completely you.

When you choose KSS, you’re doing more than booking a venue — you’re making a difference. We’re a nonprofit organization, and every dollar from weddings and facility rentals goes directly to supporting science-based outdoor education for students and campers. Your special day helps inspire the next generation to explore, learn, and care for the natural world.

From golden aspens in September to fresh alpine air in spring, our outdoor spaces allow you to celebrate in the beauty of the seasons — without the premium price tag of most mountain venues. With flexible booking options, including last-minute dates, you can create your dream wedding on your schedule.
