Casa Loma has weekday hours from 9:30 am to 5:00 with the last admission at 4:00, but you are able to take photographs of the outside of the castle anytime. We plan on returning to take indoor shots of the rooms of the castle. You might want to check their website before going as they are currently doing renovations to the castle over the next few months and some areas of the castle won't be accessible.
I especially love the wine cellar, the swimming pool and the riding stables so much looking forward to revisiting soon! There is a tragic history of Sir Henry Pellatt and the gift of the castle to his wife and the riches to rags story.
