Alder Creek Trail connects Barley Flats (at the south end) to Loomis Ranch (on the north), both of which are private property. This trail is neatly bisected by paved Upper Big Tujunga Canyon Road, which provides convenient access to our trailhead.
Loomis Ranch is the penultimate private land acquisition in the Angeles Forest, and long ago housed a hiker-friendly lodge. The new owners, unrelated to the Loomis family, prefer privacy and have not agreed to allow access (I had originally hoped to tour this historic site, but that's how it goes...)
According to the people I contacted about it, the trail was maintained shortly before the station fire. It looks ok on google's satellite view. I believe the forest service has now given up on it. I have never hiked it - this trip should be regarded as "exploratory", but I'm optimistic.
If you attend the Pacifico Mtn trip the day before, you will get excellent top-down views of Loomis Ranch and the Alder Creek area. That is the impetus for this hike.
stats: 9 miles, 1200' gain on probably fair/ok trail. It's a 45 minute drive from Sport Chalet to the trailhead. rain cancels.
