Another of my favourite kid-friendly events of the summer is the Lantern Festival at Victoria Park. If you haven't been, don't miss it. Here's their web site for all the info. It falls on the last full weekend of July. Bring a blanket to sit on and wait until the sun goes down for the magic to start. Glow sticks and homemade lanterns are welcome.
Lantern Making Workshops have begun. Check here for details on those.
