KNOW BEFORE YOU GO

Up in the Sky is a two-day mountain festival at the base of Buttermilk in Aspen, presented by C3 Presents. It's a high-country venue with big views and thinner air, so here's the short version of what to expect.

YOU'RE AT ~8,000 FEET

Aspen sits at roughly 8,000 feet above sea level, and altitude sneaks up on flatlanders — pace yourself, drink way more water than you think you need, and take it easy on day one while your body adjusts.

Dates & Venue

Runs Friday and Saturday in early August at Buttermilk — the base of Buttermilk Mountain in Aspen, CO. Expected Aug 6–7, 2027 (dates not yet confirmed).
Presented by C3 Presents.

Tickets

Alongside general admission, VIP and Cabin ticket tiers are available.
Grab passes through the official site.

Getting There

Coming from the Front Range? Denver-to-valley shuttle passes are available, so you can skip the mountain drive.

Food & Drink

Food and beverage vendors are on site, including vegan and gluten-free options.
