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
  • Friday Aug 7 and Saturday Aug 8, 2026 at Buttermilk — the base of Buttermilk Mountain in Aspen, CO.
  • 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.
