What's on site. OpenStreetMap maps 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 McKinney average 92°F. Mornings and late afternoons are far more comfortable than the middle of the day, and shade is worth planning around.
How long it's open. Roughly 22 weeks a year, from May to October. Seasons shift year to year and municipal pads often close early for maintenance, so check before a long drive.
