Hiking – High Line Canal

This walk will take us from Fly'n B Park 4.8 miles north along the canal to where it intersects S Elati Street in Littleton. It is hike #5 of 14 hiking segments along the canal. It covers segments 6 and 7 of the Highline Canal Guidebook, roughly mile 15.5 to mile 20.5. If you are new to the area, want to stay active this winter, avoid I-70 traffic, or just enjoy walking the canal, come join us. We'll be walking most Fridays.

Hiking – Lincoln Mountain Overlook Trail

Hiking – Lincoln Mountain Overlook Trail

A 3 hour easy hike up to and around Lincoln Mountain (Mesa) that lies between Larkspur and Parker in Douglas County. The trail up makes several switchbacks that makes the gradient easier. The trail is pebbly in sections, so hiking poles are suggested. Benches along the trail. Two porta-potties are at the trailhead's very large parking lot.
