Hidden Valley Park — Attraction in Martinez

Absolutely disappointing experience — not worth a single dollar!

Don’t even bother renting this park. They have the nerve to charge $300 for non-residents, which is insanely overpriced for what you get. The park was dirty and unkempt, and we actually had to clean the area ourselves before our event — how ridiculous is that after paying so much?

I have to stop by at midnight or 1:00am so as to avoid other human sounds. And you can also hear highway 4 and highway 680...
