After a show, lost items are taken to the Arenas Complex main office by the next business day. You can inquire about a lost belonging at that office located at the Denver Coliseum. If you arrive early, before the Amphitheatre gates open, you will be directed to the east stairs. When arriving prior to the scheduled gate time, you will be directed to park in the Early Bird parking lot located furthest from the Amphitheatre. Red Rocks has an ATM in the Amphitheatre located on the lower north side.
Tickets are available at different places depending on the show.
