  • Nice and secluded regional wilderness. A bit of a ride if coming from the South Bay, but interesting place. Plan ahead since it tends to be really hot. When coming in the summer months, prefer the late hours of the day. Entrance fee is (as of July/2019) $5.
  • My favorite hiking spot in the Bay area. Plenty of trails and most of which link together. They have waterways and allow dogs. Best of all, it's truly beautiful nature. I can't stand some other hiking spots with dead grass, dirt, and a few trees.. Sunol is lush and green and flowing with life!
