Not a bad way to spend an afternoon while on vacation before a Toronto Blue Jays game.
You have the garden and grounds, an audio tour, a movie about Sir Henry Mill Pellatt, the towers, the secret passages, the 800 foot tunnel to the other side of the estate under a public roadway, the stables, the wine cellar, the unfinished pool, the tale of the white stone, the gift shop......
Not a bad way to spend an afternoon. And educational too.
