Go past the turn off for coal bank, cross the creek a couple times, then you kinda drive up the creek for a bit, then maybe one more crossing, and you will end up near the drive by parking.
The "road" and the creek bed (exposed rock) are one in the same for certain stretches. It isn't necessarily an easier drive than the famous steep road (if that's what you were hoping...)
Jeff- I can take you in that way sometime- I have the scratches on my ride from bogus local beta from the RocTrip comp approach I made- trust no one the lies are out there
