The Henderson Hill trail is a short out and back paved trail to a low rise in old Rocky Mountain Arsenal area, now a wildlife refuge. Even though the difference in elevation is minimal the view is far reaching to the east and south. You can actually reach this spot using only bikepaths (route5) from Commerce City. See this ride https://www.komoot.com/tour/2710436405?share_token=aTyj2lJ1YHiQOhPskXyq8prHxb5AoOId67IJs0FNb2tJwCStGp&ref=wtd. The way that this ride got around the east side of the refuge is not recommended though.
