Grasshopper Mountain Tr3569 is a rugged ridgeline ride near the northern Middle Fork ranger district boundary with Mckenzie River ranger district, extending along the Hiyu Ridge from Lowell mountain to Chucksney Mountain.
A 5.5mi segment of non-wilderness McBee Tr3523 can also be ridden as an OAB.
The trail ascends at a steep 16% grade for the first mile from the northern FR1927 TH, which will prove excessive for most riders.
Ascending Chucksney Mtn Tr3306 from the Box Canyon TH offers a slightly more moderate approach, with the option of returning on Chucksney Mtn Tr3306 as well.
Those wishing to avoid the steep ascent can use the Grasshopper Spur Tr3314 TH
View of the Grasshopper Point TH to access the mid ride point, near Grasshopper Point, then ride OAB in either direction.
The ridgeline ride extends 2.7mi north and 5.2mi east, with the upper Chucksney Mtn Tr3306 TH as the turnaround point.
Nearby Indian Ridge Tr3315 (4.4mi) and Roaring River Ridge Tr3312 (2.6mi) are both open to biking, but are infrequently used and may not be cleared or rideable. Maybe something to check out if camping in the area.
For those seeking a shorter ride, a Chucksney Mtn Tr3306 to Grasshopper Mtn Tr3569 CCW loop offers a tough climb and fast descent.
The first 5.5mi of McBee Tr3523 is outside of the Three Sisters Wilderness area, creating a moderate 11mi (2000' ascent) OAB ride option.
The first 1.7mi is a 9% ascent, followed by relatively flat terrain out to the wilderness area.
Once in the wilderness area, McBee Tr3523 is a key connector trail, leading into the Mink Lake basin and terminating in the Horse Lake area.
Crossing Way Tr3307 passes through dry lodgepole pine over level terrain for 3mi, then becomes a steep ascent into the McFarland Lakes area where it connects with the Pacific Crest Tr2000-E.
From the Frissel Crossing CG, South Fork McKenzie Tr3327 is a quiet, leisurely day hike through the second growth Douglas-fir alongside the South Fork of the McKenzie River.
Shale Ridge Tr3567 follows the gradually sloping drainage above Cedar Bog and through a grove of giant old cedar trees, then crosses the North Fork over a maze of logs and channels before ascending steeply via switchbacks to a ridgeline and into a forested area and meadow crossing.
Constitution Grove Trail 3675 wanders through old growth Douglas-fir on a river bench, above the current river level.
Blair Lake Tr3553 is the southern connector, following a meadow around the north end of Blair Lake, then ascends out of the basin and along a scenic ridgeline.
The primitive Williams Lake Tr3589 includes steep grades through several drainages and crosses several meadows on the way to Irish Mountain Tr3588 near Otter Lake.
Irish Mountain Tr3588 maintains a moderate grade through alpine forest to Otter Lake, followed by a small meadow then on to a ridge top. The trail then passes through rolling, rocky terrain with views of the Waldo Lake area, followed by flat meadows with large ponds.
