Casa Loma was a great sight to see! Generally I don't like audio tours, but this one was better because they were like mobile phones rather than headsets. Plus, it was included.
The rooms were all different and had lots of interesting things about them. One of the best parts was taking all the circular staircases to the top of the taller tower. As you come down, there is a penny squishier, should you be a collector.
The secret passage was an interesting addition. Nothing particularly lovely about it, but the idea is intriguing. There is an archery area near the stables where you can test your shooting abilities.
