Ascent Trip Report

Approached via Sunol Regional State Park side. Park gate is supposed to open at 7 am, but the guy with the key did not get there until 7:30 am (same time I got there). Costs 5 dollars to enter the park, although there was no one to take my money at the kiosk going in or coming out. Park gate closes at 5 pm, so I was keeping track of time, and my turn-around time, on my way to Rose Peak.

Drove to end of paved road to a parking lot and followed the County High Points book directions walking 1.8 miles on dirt road along creek, then turned left up the hill at a sign indicating the Ohlone Wilderness trail. Much of this trail is not on the 7.5 minute map. Pretty easy mix of trail and dirt road leading to Rose Peak. About a 1/2 mile before the peak is a sign indicating "Rose Peak" to the right at a trail junction. An unsigned trail junction to the left is taken just before the summit.

Took only 3 hrs to cover the roughly 8.5 miles to the top. I felt pressured to move fast because of the park gate closing at 5 pm. I could not get the lid off the thick PVC pipe register. I don't think it's ever coming off. The next disappointment was that the Rose benchmark is gone. All that's left is a little cement among the rocks where it apparently used to be. From the top, I could see the Discovery peak radio tower in the distance.

Continuing east on dirt road I hit another trail junction about a mile from Rose peak. The Ohlone trail continues to the left downhill. The right fork leads to a gate with a "No Trespassing" sign. This right fork is the most direct way to Discovery Peak, the high point of Valpe Ridge and Alameda County. If one were to go this way, one would find easy, little-traveled dirt road to Rose Flat where the radio tower on Discovery Peak can be seen. A possibly unoccupied trailer is passed on the left about 1/2 mile before the summit. A second fenceline would be crossed about 300 feet before the peak.

There are many opportunities to observe cows at close range on the Ohlone trail, about the only other large mammal around although I did see one coyote. Park signs warn of occasional mountain lion sightings, but I saw none. If fact, I have yet to see one in the wild.
