Description

From the Grassy Knoll, at the top of Slant'n'Dicular, 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 past the turnoffs for Seven Bridges, Herfendoodle, and Plumber's Crack, but stay on the ridge. After an up and a bunch more flowy descent, Jumbo Ridge will end when it connects with the bottom part of Herfendoodle.

To exit the trails, follow Herf 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.
