Canyons are inherently risky. Flash floods occur without notice on sunny days. Technical skills & surrounding topography knowledge required yet does not eliminate risk.
Overview: This hike begins off the Burr Trail Road. From Boulder, drive 11 miles east on the Burr Trail Road to a small, unmarked, paved pullout on the north (left) side of the road. From the pullout, the narrow slot is visible directly across the wash. Walk into this short canyon to experience the tall walls and narrow perspective of a slot canyon. This is a short, easy, 15 minute stroll. Maps: USGS 7.5 Minute Quad: King Bench.
