You're never too old to enjoy a good aquarium.
Ripley's Aquarium is the manifestation of all things I loved growing up. The whimsical music, the room upon room of sea creatures and the walk through tunnel are amazing.
I've been here several times since opening and Ripley's never ceases to amaze. Would highly recommend coming on an off day or trying out one of their late night viewings. The structure itself is located in the heart of Toronto, right below the CN Tower - which makes for a great all-in-one-day adventure for out of towners.
Although the aquarium is geared toward children, you'll see Ripley's crawling with couples and old friends. If you're looking for something outside your typical bar night, or jays game - definitely check this place out :)
