Arapahoe Pass and Lake Dorothy Trail
Boulder, CO
Arapahoe Pass and Lake Dorothy Trail
This moderate and beautiful hike takes you to the Continental Divide by way of the valley created by the North Fork Middle Boulder Creek drainage. The campground and trail are very popular on weekends, so it is wise to get to the trailhead early. However, most hikers turn around at the Fourth of July Mine or veer off on a trail to Diamond Lake. Permits are required for backcountry overnight stays June 1 through September 15; contact the Boulder Ranger District.
