Hidden Valley Park

Pickleball players in Martinez, CA will find 8 free, publicly accessible outdoor courts at Hidden Valley Park, situated just across Center Ave. from the main park grounds at the corner of Redwood Dr. Courts are lit for night play, and the consistent daily schedule — 6:00 AM to 9:00 PM every day of the week — makes it easy to fit in a session. There is no organized or scheduled play, so drop-in style games are the norm. The broader park earns a solid 4.6 out of 5 across 645 reviews and comes with a picnic area, restrooms, and dog-friendly grounds. Visitors note the green space is generally pleasant, though some mention upkeep concerns across the property — consistent with the courts' listed condition of needing work.
