Access to Wocus and Little Wocus are off of Kirk Road. I drove from Yamsay Mtn so was driving SW on Kirk to make a loop. For Wocus, turn off of Kirk at 42.805317, -121.688200. For my activation I found an abandoned forest road that was hikable. I parked at 42.812600, -121.681117. See image below.
I saw an old signpost for FR-518. I went cross county avoiding the first looping switchback because there was no undergrowth and no bushwhack needed. When I intersected the abandoned road bed I followed it up to the summit avoiding the need for any bushwhacking through the manzanita undergrowth.
Summit is medium density forested, so you can find a shady spot and a log to sit on to activate. I did not see any great views from the true summit (pics posted to SOTA Atlas).
