High Park is fantastic because there is just so much to do! There is a Zoo, a splash pad, backwoods trail hiking, tennis, dog park, biking trails, and Colbourne Lodge historic house and gardens, to name a few. I've even seen people fishing here (*not sure if this is legal*). You feel as though you are a million miles away from downtown Toronto, which is just soooo necessary sometimes.
Its a wonderful part of living in TO!
