What's on site. OpenStreetMap maps playground alongside at this location. No public toilets are mapped here — worth knowing before you commit to an afternoon.

When to go. Peak summer highs in Hillsboro average 83°F — warm enough for a splash pad through most of the season without being punishing at midday.
