Boulder is a hiker’s paradise. Trails begin right at the edge of town and stretch into canyons, mesas, and summits that rise above 8,000 feet. On one side, the Great Plains roll endlessly east; on the other, the jagged Rocky Mountains climb higher with every mile.
For van lifers, there may be no better base: you can park at a trailhead in the morning, hike until your legs are tired, then return to your van for rest, food, and the next plan.
This guide covers 15 of the best Boulder hiking trails, complete with expanded descriptions, tips, and practical details to help you decide which to tackle first.
