Sheltered picnic area on the edge of Rocky Mountain Aresenal, with far views of the mountains and nearby metro area. There is also an ultra minimalistic Japanese style rock garden, consisting of 3 small rocks and a shurb.

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.

The way that this ride got around the east side of the refuge is not recommended though.

The Perimeter trail is the longest trail managed by the Rocky Mountain Arsenal National Wildlife Refuge. It stretches 14 miles in one direction and can be combined with some other trails in the refuge to create a huge loop. This is one of just a couple trails leaving from the refuge that allows dogs on its paths. Know that you are sometimes close to the road, though, so you won't want to let your pup run free.

The Rocky Mountain Greenway Trail, or Greenway Trail, is one of the main trails on the southern side of the Rocky Mountain Arsenal National Wildlife Refuge. It helps connect different trails to each other, but unlike some of the other trails, this one is open for bikes. Although it can be a little dry and loose, overall this is very easy, well-graded, gravel trail. Another nice feature of this trail is that dogs are not allowed.
