Parker Days 50th Annual Festival — Day 1

Parker Days returns to downtown Parker for its 50th anniversary edition with four days of live music on multiple stages, more than 200 marketplace booths, a carnival with 50+ rides, food vendors, kids' activities, and Colorado's hometown-festival energy. Thursday opens the festival from 1 to 11 p.m. on Mainstreet between O'Brien Park and downtown Parker. General admission is free; single-day early-bird carnival ride wristbands are $25 online (good for unlimited rides during one 4-hour window).
