Two city parks, four courts total, both free and run through the city's Rec reservation system: Alexander Park and Hallmark Park, the latter striped onto an existing tennis court.
Two outdoor courts under the same City of Belmont reservation program as Hallmark Park, bookable online at rec.us/alexandercourts or open for walk-up play whenever nothing's reserved. The city lists these as "Tennis Courts," and whether the pickleball lines are dedicated or overlaid on a tennis court isn't yet settled. Rec system hours run 8am–6pm; note that the city's own facility page lists this park's ZIP as 94402, which is actually San Mateo's — that's a typo, the correct ZIP is Belmont's 94002.
Two courts with pickleball lines striped onto an existing tennis court, played on a taller tennis net rather than a regulation pickleball net. Unlit, so no evening play. You can reserve here — the live booking calendar at rec.us/hallmarkcourts runs a working reservation system, and it was fully booked the Saturday we checked, with the next opening two days out. Free, with water, a playground, and a jogging track on site, but no restrooms.
