From the 1A highway west of Cochrane, follow the #40 Forestry Trunk road north for approximately 25.5km’s. Turn west on the Ghost River TransAlta dirt road, continue on another 15.5km’s passing several
red neck looking random campers until you reach a road side parking lot located above the Ghost River Valley. Park here if you don’t have a 4x4 or
an all wheel drive vehicle without proper height and suspension. Expect to add another
2 hours/6km’s to the hike time shown above. Follow the not so bad 4x4 road down towards the river valley, turn right driving or walking
2.5km's along the washed out TransAlta dirt road until you reach road marker sign #37. If it’s gone or full off bullet holes, aim towards Black Rock Mountains centre drainage on your right. The trail head is located at the bottom of this drainage. There is a short (200m) flat section of dirt road leading straight ahead to the trailhead.
Park here then cross the river bed aiming for the centre of a log jammed washout, locate the trailhead on the left side of
the washout. Riverbeds were all dry early April. Going was careful to easy in a
4runner. Pictures below were taken after the 2013 flood early April.
With a pole in hand, you can hike to Black Rock's summit along an old horse trail that once serviced the abandoned lookout. Those who have classified it as a scramble may have gotten off route. Follow the well worn trail past a back country camp spot and continue ascending through and old growth spruce and fir forest. After an hour or so you’ll pass tree line with spectacular views of the
Ghost River valley, mountain ranges, Devils Head and Mount Aylmer. Continue
ascending the talus slope until you reach the cliff base, stay on the trail as it follows the bottom left side of the cliff then turns right ascending again up a moderate gully to an open plateau below the summit.
