Dakota Ridge is an extremely rocky trail high on the Hogback between Denver and the front range. This is a very entertaining trail with rocks and staircases all over the place and some serious exposure on the tops of cliffs. Expect incredible views of Denver and the front range.
Take I-70 west out of Denver. Go past the 470 exit, and take the very next exit for Morrison. At the end of the exit, take a left (south) onto Colorado Hwy 26 at the light. Go under the I-70 overpass, and the park will be on your right 100 yards later. Trailhead is on SE side of the lot.
