The Mesa Trail is a gem of Boulder Colorado's City of Boulder Open Space and Mountain Parks (OSMP) system. The Mesa Trail has to be one of the best and most famous short trails in the country. It runs 6.7 miles from Chautauqua Park in Boulder to Eldorado Springs Drive, following a rolling and very scenic route along the foothills, with spectacular views of Boulder's famous Flatirons.

The 160-mile Collegiate Loop is formed by the East and West Collegiate Peaks options of the Colorado Trail.  It was formed when the Collegiate West option was completed in 2012.
