Since changing my morning bicycle commute route to include Cabbagetown (SO gorgeous) I now have the added delight of riding past Riverdale Farm twice a day. I have to admit I have stopped to see the animals.
Cabbagetown itself is worth the visit, as is the park around Riverdale Farm. Beautiful location, great for kids, really feels like a retreat from the hustle of the city as it is so secluded. FREE to visit. See Kat F.'s review for a more detailed breakdown on the animals that live here.
Head down the path to the south to see Riverdale park West. Farmers Market on site Mondays in the summer months.
