If you're looking for something to get you out of the house (but still away from other people) there are free audio tours of Barrie's waterfront and downtown.
Audio tours include points of interest like the Spirit Catcher, Uptown Theatre, the Barrie Armoury, the Allendale Train Station, and more in tours that can include hours of content. Along with walking tours, there are also driving tours like the Barrie to Muskoka tour that takes you to over 50 points of interest and can be complete in either direction.
