“A technical ridgeline ride with stunning views of the Kokopelli, Colorado River and McGinnis Canyons”— D L
Mack Ridge is great in either direction. There is one rather gnarly hike-a-bike in the eastern half of the trail that must be walked regardless of travel direction. (Although legend has it this has been descended!).
From the intersection with Lion's Loop and Troy Built begin a technical climb through a number of switchbacks, rocky passes, and hike-a-bike technical sections to the rim high above the river valley.
At a T-intersection with a doubletrack, turn Right. This is the original Mack Ridge trail. To the Left, the trail descends as Mack Ridge Connector to Lion's Loop. Ride East along the ridge on the doubletrack for a 1/4 mile to a short, technical, singletrack descent.
The singletrack climbs back to, and continues 3/4 mile along the rim to a particularly breathtaking viewpoint, after which ride through a Left switchback, a Right switchback and an abrupt technical section terminating in a hike-a-bike pass.
At this point, Mack Ridge is 1 1/4 miles of technical downhill. The downhill is all rideable; although not bereft of challenge. Mack Ridge ends in a saddle at the western ends of Mary's Loop and Moore Fun.
