Dogs Leashed

Features Views

Starts at the Boulder Valley Ranch Trailhead and heads up towards Mesa Reservoir. Once you reach the top, there's a panoramic view. If you go at the right time of year, you might see the rare Bell's twinpod in bloom; this yellow flowering plant is only found in Boulder, Larimer, and Jefferson Counties in Colorado. This trail is only open to foot-traffic and equestrians; no bikes allowed.
