Denver's been blessed with great street art over the past few years, thanks in part to Denver Arts & Venue's Urban Arts Fund, led by Mary Valdez, which pairs paid artists with walls all over the city: under Globeville viaducts, on the sides of RiNo buildings and, last year, along the Cherry Creek Trail. This urban gallery is too impressive to whip past on a bicycle, though. You need to be able to walk between pieces and stop to study such marvels as the ode to Denver created by Nigel Penhale, and "City of the Sun," a deep-blue and gold mural by Colorado mandala artist Gemma Danielle that caught the eye of Americans for Arts.
