High Line Canal is a 28.6 mile out and back trail located near Sedalia, CO and is good for all skill levels. The trail is primarily used for trail running and is accessible year-round.
Um the google map lead me to a turnoff into a farm with it's gate closed. I have run the canal before, it is great, but this trailhead according to the map didn't exist. Get on the highline at arapahoe and university.
