Editor's Take

A practical free option with more structure than a casual neighborhood splash pad; the timed-entry system helps with crowding but adds some friction.

About the Venue

Mercer County Park Spray Park is a free county-run splash area next to the marina in Mercer County Park. It offers in-ground sprays, mists, colorful sprayers and sprinklers, plus a shade structure with tables underneath. Families should plan around the park's attendance system: entry is first-come, first-served, limited to a 60-person capacity, and organized in 45-minute sessions with a cleaning break between groups. It is a strong warm-weather stop for mixed ages, especially if you want a larger park setting around the splash visit.
