You step out of a parking garage and the Flatirons loom to the west, their jagged faces shading the city as you tap through the first clue on your phone. Downtown Boulder becomes a playground — alleys, public art, and sandstone outcrops are all part of the game. The hunt threads Pearl Street Mall, side streets lined with cafés, and small plazas that reveal the city's mix of outdoor culture and civic art.
