Bear Gulch follows an old road up a narrow and sparsely-forested creek bottom to a steep (13% grade) singletrack trail that climbs to the southwest saddle of Johnstone Peak. It is one of the few trails that is open to motorized use in the Pioneer Mountains, and it is typically maintained every spring by local motorcycle riders.

The Bear to Parker mountain bike ride is a granny-gear grind, one of the steepest and most consistent climbs in the valley. The descent down Parker Gulch is fast and occasionally loose. The Parker drainage faces west and tends to be hotter, drier, and dustier than Bear Gulch. About half of the Parker descent crosses open sage and grass, and the other half crosses through shady forest. The trail tends to be somewhat looser than the Bear Gulch side, so it is preferable to ride up Bear and descend Parker, but it can be ridden in either direction.

Parker Gulch was one of the epicenters of mining in the 1880s, and many old roads crisscross the steep hillsides between tailings piles. Isaac Lewis, who also founded the town of Ketchum, owned the Elkhorn Mine at the mouth of Keystone Gulch. Other notable claims up Parker Gulch were the Amicus, Parker, and Montgomery Mines. The road to the Parker Gulch Trailhead passes through several parcels of private property, so please respect the landowners.

Additional Adventures

Bikers can piece together a huge loop by beginning at the Trail Creek Trailhead and riding out the Corral Creek Trail, then out the Corral Creek Road to the Pioneer Cabin Trail.  The first descent takes the Johnstone Creek Trail down to Hyndman Creek road and to the Bear Gulch Trailhead. From here riders complete the second grueling climb over to Parker Gulch and finish on the bike path system back to their car at the Trail Creek Trailhead. It is a leg-burning 30-mile ride that climbs 5,660 feet (add 2.2 miles and 629 feet for the round trip to Pio Cabin at the top of the first climb).

Off-Trail Hiking

From the saddle on the southwest ridge of Johnstone Peak it is an easy Class 2 scramble to the summit for the most amazing panoramic view of the Pioneer Mountains. It is possible to make an off-trail loop by descending east off of the summit and then following the meandering south ridge down to the Bear Gulch Trailhead.
