It's called Little Basin. Presently, it's privately owned by HP but they're about to donate it to a preservation group. I'm going from the San Jose Amtrak down Saratoga Avenue and up highway 9 to 236, through Big Basin and the camp is just south of there, off of Little Basin Road.

I'm looking at about 4000' of climbing with a mix of long and steady, steep and twisty, and a lot of rollers. Definitely more climbing than I've ever done. But I've ridden 4500 miles this year and a lot of that was on a fixed gear in the wind, which actually does a pretty good job of preparing a flatlander for hills.
