The centerpiece of this 10-acre county park in the Rancho San Diego area is a pirate-themed splash park that costs $3 per day, with a $30 season pass or a $75 three-person family pack available. There is no lifeguard, children under 14 need adult supervision, and non-potty-trained kids must wear swim diapers; the park also offers a playground, sports field, basketball court and shaded picnic areas.
What's on site. OpenStreetMap maps drinking water, playground alongside, parking at this location. No public toilets are mapped here — worth knowing before you commit to an afternoon.
When to go. Peak summer highs in El Cajon average 86°F — warm enough for a splash pad through most of the season without being punishing at midday.
How long it's open. Roughly 22 weeks a year, from May to September. Seasons shift year to year and municipal pads often close early for maintenance, so check before a long drive.
