I was up in Napa at a work retreat. After hanging out by the pool for a few hours, I had to get moving. The concierge at the hotel recommended that I check out this park. I did a 7 mile loop, and was almost late getting back for dinner. I would have loved to stay out longer. There were some really cool trails out there. I liked the overgrown ones the best. Lots of great wildflowers. Hardly any people besides a few mountain bikers.
