Two city parks: Don Biddle, where tennis courts double as striped pickleball lines, and the newer Wallis Ranch Community Park, which added dedicated pickleball courts in 2025 alongside more tennis-court overlays. Play is free and mostly drop-in, with a handful of reservable slots at each.
Two tennis-court slabs, each striped with two pickleball lines — count the striped lines and that's 4 courts, count the physical slabs and it's 2, so you'll see both numbers depending where you look. "Court 2" is free and drop-in at all times; "Court 1" can be reserved ahead through dublinrecguide.com, except during the sunrise–1pm window when it shifts to tennis priority. Nets are portable and city-owned — players set them up and are expected to secure them after play.
Dublin's newest park (opened August 2025) and the only one built with courts purpose-made for pickleball: 4 dedicated courts with permanent nets, plus 8 more striped onto the park's 4 shared tennis courts (two lines each), for 12 total. The city's reservation system only names those 4 shared tennis courts — two bookable through dublinrecguide.com outside the sunrise–1pm window, two drop-in only — and whether the 4 dedicated pickleball-only courts follow the same booking rules or are entirely first-come-first-served is unconfirmed, so check before you count on reserving one.
