“The classic big loop on Jumbo and a classic Colorado climb followed by a long descent that is as good as it gets.”— Judd Kleinman
Don’t miss the hammock at the top, relax and enjoy the spectacular views.
To ride to Jumbo Ridge, the highest point of the trail system, enter the trailhead gate (if it's closed, keep it closed; cattle may be grazing the area) and proceed east on Gully Trail. Do not take a left turn uphill from the trailhead to parallel the housing development, or you'll be riding up the recommended downhill route, Elitches.
After approximately a mile on gentle up and down terrain on Gully Trail, you'll come to the Powerline Road which sits directly ahead of you as you come off the singletrack. In a few hundred yards the road curves left and then up to a high-tension powerline tower, AKA The Tower of Power, at the top of the hill. Just before the Tower of Power, the Powerline Road turns almost 180 degrees and heads up the ridge to the northeast. As the Powerline Road leaves the ridge and breaks to the left, the start of Slant n' Dicular is straight ahead.
Begin a steady climb (1.6 mi) with some switchbacks up Slant n' Dicular to the Grassy Knoll. You are now on the north shoulder of Jumbo Ridge. Enjoy the spectacular view of the West Elk mountain range, with iconic Mount Lamborn and Lands End in the forefront.
From the Grassy Knoll, you proceed up and to the east or left where Slant joins Jumbo Ridge at the Grassy Knoll. As you reach the top of this short climb, be careful as the trail begins to traverse the face of Jumbo and drops into the Toilet Bowl.
CAUTION: exposure and rough terrain.
Most of the face is rideable until the final 200’ or so of hike-a-bike terrain. Take a break here and enjoy the hammock, you have reached the top of the Jumbo Ridge trail. On the descent, you ride a fairly technical, fun, and stunningly beautiful section of trail as it crosses the upper flank of Jumbo Mountain. You'll pass the turnoff for Rock n' Roll on the right and do a short grunt to gain the southeast shoulder of Jumbo Ridge.
From here, the trail descends for 1.5 miles. Toward the bottom, you'll scream passed the turnoffs for Seven Bridges, Herfendoodle, and Plumber's Crack, but stay on the ridge. After an up, and a bunch more flowy descent, you'll connect with the bottom part of Herfendoodle and follow it over a bridge and up to Bang Zoom, passing the Cactus Cut Off on the right.
At Bang Zoom, take a right and follow it for about a ¼ mile looking for a sharp left onto Zip n' Out. Take Zip n' Out across Horseshoe Ridge and follow it until it crosses the gully and joins back up with the Gully Trail. Hang a left here and follow Gully back to the trailhead.
