1. The Classics: Boulder’s Signature Trails

Boulder’s most recognizable landmarks are the Flatirons, five dramatic rock formations that jut from the earth just west of downtown. They serve as a backdrop for many of the city’s best-loved trails.

Chautauqua Loop Trail

Starting at the historic Chautauqua Park, this gentle loop winds through grassy meadows and into the lower slopes of the Flatirons. Wildflowers bloom along the trail in warmer months, and benches invite hikers to take in the expansive scenery. It’s a favorite among families and casual walkers.

Green Mountain Summit Loop

For a more ambitious trek, this trail begins near Gregory Canyon and climbs through pine-scented forest toward the summit of Green Mountain. As elevation increases, so does the sense of solitude. At the top, hikers are rewarded with broad mountain views, especially stirring when clouds sweep across the peaks.

Mount Sanitas Trail

Located just a stone’s throw from downtown Boulder, Mount Sanitas is a classic for locals and visitors alike. The climb is steep and rocky, perfect for those looking to break a sweat. The payoff comes in the form of open ridgelines and an eagle’s-eye view of the city below.
