2.1 mile loop winding through mostly oak grassland, at the edge of San
Distance, category, and difficulty:
This 2.1 mile partial loop hike is easy, but there are a
few steep trail sections. Trailhead elevation is about 450 feet. Preserve's
high (trail) elevation is around 1000 feet. Total elevation change on
this hike is about 500 feet. Even with the steep trail sections, you'll
likely fail to exhaust your resources at this small preserve.
Mostly exposed, with some shade.
Dirt fire roads and trails.
Too hot in summer. Best in late winter and early spring.
From Interstate 680 in Contra Costa County, exit Bollinger Canyon Road
(exit 34). Turn west onto Bollinger Canyon Road, and almost immediately
turn south (left) on San Ramon Valley Boulevard. Drive south about 0.7
mile, then turn right onto Morgan Drive. Drive on Morgan about 0.2 mile,
to the signed trailhead on the left side of the road.

not offer day-long hiking challenges. It's a 529 acre chunk of land not
far from I-680 and the residential neighborhoods of San Ramon; open space
best suited to dogwalks, pre- or post-work human exercise, and springtime
picnics under old oak trees.
Three main multi-use trails, and one narrow
hiking-only path (so minor, that in this cow-grazed preserve you may have
trouble finding it) comprise Bishop Ranch's trail network. There are a
couple loop options combining Stream View, Grey Fox, and Red Tail Hawk
Trails, or you can hike out and back from the southeast preserve boundary
to the northwest border on Grayfox and Red Tail Hawk Trails. If you have
a free afternoon, the preserve is small enough to explore extensively
in a few hours. But it was hard for me to drag myself past the junction
of Red Tail Hawk Trail
and Stream View Trail. From one spot near that junction on the grassy
ridge, if you position your gaze correctly you can see Mount Diablo and
its foothills, without a single building, street, or freeway visible.
Rolling treeless hills block out civilization, if only for a few degrees
Although the transition to autumn is marked
appropriately at Bishop Ranch (the deciduous valley and black oaks take
care of that), spring boasts gentle temperatures, grass of the greenest
green, and wildflowers. When the wind ripples through the verdant, flower-dotted
grassland on a balmy April day, you may just want to sit and stare at
the perfect and astonishing ordinariness of nature.
Start out from the corral-like staging
area on the obvious trail. Tall clusters of wild mustard line the path
in spring, while tangles of willow guard a seasonal creek on the left. The trail curves left, crosses the creek, then passes through a cattle
gate and after about 300 feet, reaches a signed junction. Hiking-only
Stream View Trail begins on the right, while Grey Fox Trail continues straight.
Continue uphill on Grey Fox Trail.
The trail, open to hikers, equestrians,
and cyclists, climbs very sharply through valley oaks and grassland. After
only a couple hundred feet, on a clear day a view back over your shoulder
will reveal Mount Diablo. Traffic noise from I-680 is audible.
California buttercups, spring vetch, and blue-eyed grass dot the grass
in springtime. The trail may be rutted and bumpy from cow traffic. Grey Fox
Trail nears the preserve boundary, a fence guarded by poison oak, then
turns right and continues to climb, but the worst is over. At 0.22 mile a
fire road heads out of the preserve to the left. Continue straight.
The trail passes beautiful large valley oaks gracing the grassland. At
0.31 mile, Grey Fox Trail meets Stream View Trail at a signed junction.
Turn right onto Stream View Trail.
The wide multi-use trail heads downhill
through stands of valley oaks. Buckeyes cluster together in the creases
of the hillside. At a moderate grade, Stream View descends on a series
of broad switchbacks. The hiking-only segment of Stream View heads back
toward at the trailhead from a signed junction on the right at 0.47 mile.
Continue straight on the fire road.
Coast live oaks blend into the white oak
woodland as the trail continues downhill, then levels out. The seasonal
stream sits off to the right, but is only visible a bit further up the
trail. You may notice the remnants of a large landslide near the park
border and houses. When I hiked here on a September day, some of the preserve's
cattle scampered away from me like timid deer. Black oaks mix through
coast live and
valley oaks, shading the trail. There isn't much in the way of an understory,
but poison oak and snowberry are common. Stream View Trail begins to climb,
somewhat steeply, away from the creek. The trees thin as the trail rises
into grassland, gaining elevation in a series of sweeping curves
and straight ascents. Finally, as Stream View Trail approaches
the ridge, pure grassland flows uphill. In spring the grass is a wave
of lush green. At 1.24 miles, Stream View Trail ends at an unsigned
junction. Turn left onto Red Tail Hawk Trail. (You could also turn
right and follow Red Tail Hawk Trail to the preserve boundary,
about 1 mile, then return to this junction.)
The ridge falls away on the right, west
side of the multi-use trail. This treeless grassland fosters wildflowers
in the spring; you might see owl's clover, spring vetch, broadleaf
filaree, crimson clover, fiddlenecks, and California buttercup before
Easter, then California poppy,
lupines, and mule ear sunflower a bit later. By autumn the grass is golden
and inhospitably infested with yellow star thistle. Since the small size
of this preserve prevents a long hike, if you're visiting in spring
you may want to plop down in the grass and watch the redtails soaring
through the sky, or creep close to the ground and look for the owl in
owl's clover. Red Tail Hawk Trail's grade is nearly flat, and on my springtime
hike the wide trail was mostly covered with grass, enabling a very cushy
stroll. The trail descends a bit, to a signed junction at 1.41 miles.
The trail straight is a dead end. Turn left on Grey Fox Trail.
Descending at a moderate grade, there are
sweeping views of Mount Diablo and the San Ramon Valley.
Grey Fox's grade steepens, levels off, then descends some more, to a familiar
junction with Stream View Trail. Continue straight, and retrace your
steps back to the trailhead.
