Driving Directions

From a diversion dam on the South Platte River 1.8 miles upstream from the mouth of Waterton Canyon, the canal runs 66 miles (106 km) east-northeast through Douglas, Arapahoe, and Denver counties, ending at the Rocky Mountain Arsenal Lateral in the Green Valley Ranch area in northeast Denver. The canal is accessible along most of its length. To reach its starting point, take Colorado 470 to Wadsworth (Colorado 121) and follow Colorado 121 south to the Kassler Center.


Discover Denver's nature, history, and rich culture along the 71-mile High Line Canal. An extraordinary feat of engineering now nearly 150 years old, the Canal is outliving its historic function as an irrigation utility and has taken on new life as a recreational and ecological resource. Relatively flat, with paved and soft-surface portions, the Canal trail gives everyone an opportunity to get outdoors. Run, walk, bike or horseback ride from the foothills to the plains.

The Canal runs through 11 distinct communities and is cared for through partnerships between the High Line Canal Conservancy, Denver Water, the various jurisdictions, and UDFCD. The High Line Canal Conservancy is a nonprofit that was formed in 2014 with the mission to preserve, protect, and enhance the High Line Canal in partnership with the public. The Conservancy is providing collaborative leadership to reclaim the historic waterway for the region to ensure permanent protection for all 71 miles (over 860 acres), enhance public use and improve the Canal's environmental health.
