Although I've listed this as a drive-up, Tom and I parked on Sulphur Springs Mountain Road just as it turns off of Ojai Santa Paula Road. From here we elected to ride our mountain bikes. The road is a nicely paved road, which you can drive, that goes four miles up to a gate. From here it is a short walk to the summit. We had a nice afternoon at the summit, enjoying 2m/FM, 20 and 40m/CW, and lunch.
