Comfortably Brampton's most popular park. This is an urban recreational park and not so much of a nature escape. It's well thought and laid out - very much part of the civil engineering project that is Bramalea.
They've really tried to squeeze in about everything you can consider: large playground, water splash pad, pond, mini botanical garden, concession, mini ski/toboggan hill, beach volleyball area, chalet, football field, petting zoo, reception hall, and probably a couple other things. They even built a natural amphitheatre with a steep, shaped hill where you can watch concert bands in the summertime (the Ching concert band). 
The park is also part of the Chinguacousy trail - a continuous trail that virtually runs over half the north/south length of the city. Terrific for joggers.
As imagined, the place is VERY busy in the summertime. In addition to everything above, they also have a carousel and miniature train for kids.
My critique is not so much of the park itself, but the city. The park becomes far too crowded during the summer. At the heart of the park, you're practically shoulder to shoulder with others, and you need to ensure your child doesn't get overrun by the several dozen other kids in the same play area. It speaks of the park's draw, but also the lack of other options. Brampton has a lot of 'parkettes' to their credit, but very few proper parks for a city its size. Decades ago, the city planners felt this park would serve its city well. The city has probably tripled in population since, but they city now has no problem zoning generic urban sprawl development with pathetic excuses for parks - or parkettes as they're known.
Terrific park, let's hope today's city planners see that and provide something similar as they're creating new communities in the city.
