John et al, tomorrow we're setting up by the visitors center, the place on the 2nd link you sent. That's why the title of this thread is "Pinnacles west side visitors center."
I like the Chaparral parking lot too, at the trailhead. Still decent horizons, and breathtaking views of the hoodoos before, during and after sunset. The Chaparral lot is at the end of the road, it's past the parking lot you highlighted on that first link. Hard to miss that detail, the road really does end there, no road goes thru the Pinnacles.
