Livermore

Four dedicated outdoor courts with permanent lines and nets on a 4.5-acre neighborhood park, built out specifically for pickleball rather than converted from another sport. Free and walk-up only — LARPD lists no set hours beyond "drop-in." You may see this same park listed twice under the shortened name "Livermore Downs" (no "Park"); it's the identical four courts, not a separate venue.

Eight courts split evenly: four (1A, 1B, 2A, 2B) have LARPD-installed permanent nets, the other four (3A, 3B, 4A, 4B) are lined for pickleball but you bring your own net. Free for walk-up play, or reserve ahead for $10/court/hour on the net-equipped courts and $5/court/hour on the lined-only courts — non-refundable, five business days' notice required. Part of a larger park with a dog park, swim center, and the Rincon branch library next door.

An indoor drop-in program on a shared gymnasium floor — permanent pickleball lines with portable nets brought in for sessions. How many courts actually fit is genuinely unsettled — anywhere from 3 to 6, which likely just reflects how many portable nets get set up on a given day. Pricing has shifted too: LARPD's current rate is $7 ($6 for seniors) per visit, though you may still see an older $6/$5 quoted — go with the current $7/$6. Drop-in sessions run Tuesday and Thursday 11:30am–2:30pm and Wednesday 6–9pm.

Two shared tennis/pickleball combo courts, resurfaced in 2002 and not lighted — the oldest court surface of the venues in this guide. Free, walk-up only, with no listed hours beyond drop-in. This one flies under the radar — it's a legitimate, official LARPD facility that most pickleball listings simply miss.
