The Experimental Farm in Ottawa is allowing access to the barns for free! Well, they ask for a donation, but there is not a place to put the donation once you get there.
I took my family this morning and it was a great time. They have horses, pigs, sheep, and a whole barn of milk cows. Great for kids to experience animals they usually wouldn’t see in the city. But be sure to make the trip before Friday this week, because the farm starts charging after that.
The Agriculture museum is also available on-site, but you have to pay for admission.
