There is actually a pretty well worn trail leading up the south side of Eagle Cliff, the start of which is shown here. From CO 66, park at the gate on the dirt road behind the Dunraven Inn. Follow the dirt road a few hundred feet to a sign marking an intersection of paths. To the left the trail leads to Moraine Park, to the right leads up a driveway. Follow the driveway for fifty feet to an eroded trail fortified with waterbars shown above.
