Upper and Lower Cow offer the best “remote like” setting in Real Hidden Valley. Real Hidden Valley can harbor as many tourists (climbing and otherwise) as the Hidden Valley Campground itself on any given day. But Upper and Lower Cow stretch out into the northwest end beyond the loop trail, high above the wash below offering serenity.
Upper Cow enjoys a beautiful ledge perched below the majority of its routes and features several sport climbs that rival the more classic bolted lines that are popular due to easier access: Udder Chaos, 5.10c** and Hollywood and Bovine, 5.10d**. Two mixed lines utilizing horizontal gear placements are located to the right of the before mentioned bolted lines: Reach for a Peach, 5.10a* and Cottage Cheese, 5.9*. In between these four is a 5.10aR* named after the wall itself, Upper Cow, that I thought protected fine (no relative run out in my opinion). One bolted rap is located atop Udder Chaos. You can set a gear belay/top rope above the right side of the wall. Cow Pie Corner, 5.6, is a quick and easy solo at the right side of the before mentioned routes. A few stragglers are located even further to the right as you descend from this main upper wall. One is located by itself on the far left (photo): Cowabunga, 5.10c*.
You can take a left or right on the main loop trail. At the opposite end of the canyon from where you first intersect the loop trail is a wash that travels out of the canyon to the northwest. As you leave the loop and enter the wash, you pass the Brown Wall on your right and then a varnished wall rising out of the wash where Savwafare 1st Everywhere, 5.8**, is located. Although this route is included with the Lower Cow formation routes in the guide, it is not on the Lower Cow Wall. Rather look up high above the canyon floor on your left (north facing) and you will locate the Lower and Upper Cow Walls (photos). The Upper Cow Wall is stacked above the Lower Cow Wall. There is no discernible traffic up from the wash. Access to the Upper Cow is best approached from the right (west) vs left.
