I would be cautious about parking at the Two Trees TH. There was a lot of window glass on the ground there. Eighty minutes to the summit from there, via the road and herd paths that braid with the main trail.
Surprised to spot fool's gold in the creek... interesting granite up there, too. Views would've been excellent on a clear day, but alas there was mist.
Hiked from day use parking lot to the summit, then on the "M", back to the lot then the other way to Table Benchmark. Cool boulders near Table BM.
Heather and I hiked the north divide road to bag Trabuco, Horsethief, Los Pinos, and Vicker. When we were done we drove over to Box Springs. Watch out for the brain-scramble from the summit towers.
I used to hike to the C when I was a student at UCR in the late 1980s-early 90s. Never hiked to the tru top (el 3080 ft) until today. Nice hike up trail and access road. Views down were hazy, just like I remember it. Top features a monumentally ugly building and tower.
Nice park just east of the summit with a good trail leading to the top. Trip Report
Took the M Trail. Nice leisure hike in the Inland Empire.
Box springs is a nice hike to take with a dog.
Fun climb, lots of geo caches around.
Many good days working on new problems.
Lots of untapped bouldering up here!
