Check the city's FB page. Big Rocks Park was not open when I visited last Friday, July 10th. I saw that they were closed from Thursday at ~5pm to Monday at ~8am, if I remember correctly. The large parking area was not accessible. But, there is a small parking area near the road & picnic tables where you can still get in. There were people in the park that day.
