Really nice castle and the self guided audio tour is a great idea. We came on a beautiful day and glad we did because it gets really warm inside the castle and when the weather is nice you can enjoy the fountain in the front and in the rear garden. Afterwards, take a stroll down into the garden to see a bunch of plants and flowers and walk pass the small pond. The tunnel was interesting in order to get to the garage and stable which could have been my favorite spot in Casa Loma. The inside is nice don't get me wrong and we did learn a lot, however being from New York, the history lesson was a little dry. The "secret passage" to get all the way up to the tower is NOT WORTH IT! It is hot and stuffy every floor you go and only one stair up or down and its pure chaos with no staff there. I am glad I did Casa Loma because I am a tourist and it was included in the City Pass Toronto we purchased
