Best time to go to this park is during Oakville Children's Festival! In 2017: Sunday July 9 from 10 a.m. to 4 p.m.
I was seduced by Coronation Park's setup by the lake and by the choice of things to do. The spray pad was surrounded by a lawn and beautiful tall trees with peculiar knots. My kids spent as much time refreshing themselves under the water sprays as they did inventing games with the thousands of plump pebbles on the nearby beach in the shade of wide trees (a paved trail leads to this beach). I strongly recommend you bring a toy truck to add to the fun. A very nice playground is located on the premises. It includes two stimulating climbing structures, one of them wooden with a hanging bridge and a tunnel-shaped slide, and 3 small climbing walls. I recently visited the spray pad which was fully renovated a few years ago and now offers a castle theme. Check it out!.
