DRIVING ROUTE 1
- Go north on I-5 to the town of Gorman. Get off on the signed Gorman
- Turn left at the bottom of the off-ramp and go under the freeway.
- Go 0.1 mile to Peace Valley Road. Turn right.
- Go 1 mile to the entrance to Hungry Valley Recreation Area on your
left (paved). Turn left. Note your odometer and go as follows:
- At 0.2 miles, entrance station. If manned, you can
avoid payment of the fee by telling the State Park employee that you are
passing through to Alamo Mountain.
- At 5.2 miles, intersection. Turn right (west) toward "Piru Creek",
- At 11.4 miles, Piru Creek crossing. There is a seasonal gate just
before this stream crossing.
- At 13.4 miles, the pavement ends.
- At 17.8 miles, fork to the left. Keep right.
- At 17.9 miles, junction with the Alamo Mountain Road. Turn left.
Note your odometer again and go as follows:
- At 3.3 miles, fork immediately beyond a small road cut through the
- At 4.0 miles, the road continues east at the Little Mutau trailhead.
Past this point the road can sometimes be poor but is usually passable.
- At 6.3 miles, the parking spot for McDonald Peak.
- At 7.2 miles, a dirt berm, a sign indicating no further motor vehicle
and a large parking area, suitable
for car camping. Park here.
HIKING ROUTE 1
- From the parking area (6500'), pass the gate and hike east on the old
road for 1 mile to the obvious high point of the road. This is the
summit area of Sewart Mountain.
- Continue downhill
on the old road for about 0.5 mile to a fork with an obscure road on
the right, signed "Sespe Wilderness". Turn right onto this road
(continuing straight leads to Snowy Peak and
Black Mountain #2).
- Follow this overgrown road as
it first descends steeply south to a saddle, turns east over bump 6043',
then proceeds downhill in roller-coaster fashion.
- After about 2.5
miles, the overgrown road turns to trail. Follow the trail eastward onto
the northern slopes of a forested ridge, looking for a side trail coming
steeply in from the right, possibly signed "Cobblestone Trail".
- Turn right on this side trail, which is very deteriorated and should be
considered cross-country travel.
- Take this old trail as it goes southeast
up a ridge. After a long 1/2 mile it comes to a fork in a shallow saddle
with the remains of a sign (5840'+). Turning right on an overgrown trail
at this saddle goes to Cobblestone Mountain.
- Continue straight (east) along the ridgeline following a spotty use trail
over and around several bumps. The route turns into the saddle north of
bump 6138', and then ascends through brush to the summit.
White Mountain #2 is often combined with Cobblestone
Mountain into a hike of 18 miles round trip with 6500' of gain.
The peak is in the Sespe Wilderness, but permits are not
required at this time.
Contact the USFS at (661) 245-3731 for information about the status of
the seasonal gate at the Piru Creek crossing.
