Best time to go there is spring. There is a lot of fruit trees and when they bloom is absolutely gorgeous there. But.....last few years they bring tourists on the buses and it's hard to walk around. Unfortunately. Other then this park is very big and you can find quiet place. It has restaurant with some healthy options not only hamburgers and big patio. Big playground for kids where food trucks are coming and little ZOO for kids. They have hours with some activities for kids too.
Winter time you can enjoy ice-ring.
It's better to park from Bloor Str. or Parkside Dr. The Queensway have limited parking spaces.
You can go from there to Lakeshore Blvd. and enjoy walking along the lake.
