First explored this area as a kid,long before it was a park, and had no idea at the time it has the rich volcanic history that it does. As a so-called summit, well, between the trees and the antennas and all, it's a claustrophobic summit experience, but a short walk to one of the hilltop highpoints in the park to the east, and you'll get that feeling as you look over much of Contra Costa County.
Quick trip on a sunny day. Park was pleasant enough but not quite as great as I'd hoped. Suppose there were just a few too many people and a lot too many antennaes. Went to Briones Park two weeks earlier and found it to be a lot more remote feeling (happened to be a slightly clearer day too).
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
