Jul 12, 2025 Chapman Drive Trail Report

Trailhead at Boulder Cyn Dr is closed for upgrades. Trail is open. Path from Boulder Creek to Chapman is blocked and law abiders will get onto the highway for a 0.1 mile shunt around this blockage. Law breakers will proceed to the plastic barrier and carry their bikes over it, though the construction workers may not like you treading over their work, so only do this after hours/weekends. No judgement. https://bouldercolorado.gov/media/17230/download?inline
