Ascent Trip ReportAccess notes:
From East San Jose, take Mt. Hamilton Road (CA-130) east into the hills, topping out at Lick Observatory on the summit of Mount Hamilton. Highway 130, now called San Antonio Valley Road, begins descending steeply into the namesake valley. Stay on this narrow and windy road heading generally eastward, until it makes an obvious wide turn to the north. A gated dirt road is visible to the driver's right on the south side of the road at this point. Instead of parking by the gate, backtrack a few hundred feet uphill and park next to the last cattle guard crossing. The distance from the intersection of Alum Rock Ave and Mt. Hamilton Rd in East San Jose to the gate is approximately 31.2 miles and will take almost an hour and half to drive due to traffic conditions.
As with Boardman North, one does not want to spend any more time than strictly necessary by the side of the road. However, San Antonio Valley Road sees far less traffic on weekends, and most of that traffic consists of bicyclists. Still, an early start is imperative. From the parking area, walk to the gate and proceed past it on a flat dirt heading south through the recently created San Antonio Valley Ecological Preserve, administered by the California Department of Fish & Wildlife. After about 1/2 mile, a less distinguishable road branches off to the left (east); there are signs for Ponds 11-10-9.
Follow the pond road in an easterly direction, hiking through a lovely grassy plateau, then along the side of a stream coming from the hills looming to the east. In the spring there are several spots to cross where the stream intersects the road, and the track can be muddy. We saw plenty of footprints from cows, feral pigs and other animals roaming around.
While paralleling the stream, the road gains elevation modestly, with several ups and downs. One should stay left at a couple of junctions where other roads continue south and east respectively. After passing a gate marking the boundary between the ecological preserve and private property belonging to another owner, the road begins a steep climb up the south flanks of Stakes' west ridge. Most of the elevation gain is in this section.
The road tops out at a saddle at 3400 feet, with another road dropping down to the north. Continue east on the main road towards the round summit of Mount Stakes, now clearly visible. With less than 1/2 mile left, there is a junction with two options for continuing. To the left is the main road eventually reaching the top, but taking more distance to do so. To the right is a steep firebreak leading to the main ridge, which has a barbed-wire fence marking the boundary between Santa Clara and Stanislaus counties. The Santa Clara side of the fence is brushy and unappealing, but the Stanislaus side has a nice dirt road running alongside the fence. The official USGS benchmark with 'Mt Stakes' on it is under the barbed wire fence, on the bump where the firebreak terminates at the fence. Squeeze through the fence, then stay on the new dirt road as it dips gently, then rises to the main summit.
Views are nice and open in all directions. The huge expanse of Henry Coe State Park unfolds to the south, while the snow-capped Sierra shimmer in the distance to the east. Hamilton and Copernicus stand out to the northwest, while the Diablo Range extends northward and southward as far as the eye can see. No register is present. There is another benchmark in a modest rock pile at the official summit, but it does not identify the peak.
On the way back we stayed on the main road on the Santa Clara side, which only added an extra 1/4 mile distance. The descent down the steep section is much faster than expected, and the rest of the hike out is a pleasant stroll through the ecological preserve and its streams. Once back on the flat north-south road, one should not linger and move to get out past the gate before any vehicles pass by on the paved road.
Approximate stats are 11.6 miles and 2050 feet of gain. A GPS track is available, but will not be posted here. Contact me for additional information.
