Red Rocks is famously strict about bag size—and for good reason. Your bag must be smaller than 10” x 6” x 2”, which is roughly the size of a paperback book or a small clutch. If you show up with a backpack that could double as camping gear, you’ll be turned away faster than a bad cover band.
Here’s the kicker: clear bags are your best friend here. Not required, but they speed up security like a VIP lane. Think of it as a see-through superhero cape for your gear.
