When I got to the park not long after 10a I found a whole collection of
firefighters from various agencies at 
the entrance staging area
preparing for
some sort of drills/exercises. I walked past them wondering if someone was
going to tell me the park was closed to the public today, but nobody seemed to
take much notice of me, or at least not enough to ask me what I was doing. I
hiked up the 
main road
to the south through the Upper Ranch section of the park,
passing through the 
Sycamore Campground
and then sticking close to the park
boundary on the SE side. A very difficult route that goes pretty much straight
up a steep ridgeline has been closed for some time due to
excessive errosion
that has made the route dangerous. Not too difficult for hiking however, and I
was happy to be on a route that would see no traffic. This route no longer is
depicted on the park maps (nor are several old motorcycle tracks that I took
advantage of) but shows easily in the satellite view. I
followed this up to
Hector Heights Overlook, the highest point in the park. As one might expect
from the name, there are fine views of the surrounding 
Gabilan Range,
the
Diablo Range to the east and the 
Hollister area
to the north. A gate barring
vehicles leads along the fenceline to a small 
antenna site,
the park boundary
found just beyond this. I passed through a break in a barbed-wire fence to
find some lightly used ranch roads leading to the summit less than half a mile
further. Though several hundred feet higher, the views are no better thanks to
some high brush and 
stately oaks that partially block views.
There is a decent view to 
Fremont Peak about 4mi to the northwest and
Pacheco Peak can be seen prominently in the Diablo Range 20mi to
the northeast.
After returning to Cienega Rd where I had parked, I hiked a short distance
along the road to a gated entrance to the Hudner Ranch section northeast of the
road that I used to access the second summit, Peak 1,438ft. This park
section is not as steep
and rugged as the Upper Ranch, offering a more relaxed 4x4 experience (though
not without its own challenging route options). I followed
various road branches
around Pt. 1,320ft, then struck off cross-country on a game trail to traverse
the south side of Pt. 1,419ft and reach the park boundary for a second time.
The grass on the private ranch lands has been mowed to nearly bare earth by the
cattle that graze here,
making cross-country much easier than it is inside the park. I climbed the
easy slopes to 
the top
of Peak 1,438ft where I found a black water tank and
views overlooking miles of ranch lands with a nice profile of the Diablo Range
in 
the background.
I found a much more direct return route that stayed outside
the park, partly using the ranch roads and partly some cow paths to get me back
to Cienega Rd. I spent a little over 3hrs on the hike to the two summits at a
fairly leisurely pace. Springtime would make for a much nicer visit when the
hills are freshly green, but I was happy to pretty much have the place to
myself (the firefighters must have been exercising in another part of the park
since I never saw them or their vehicles on the route I took).
