Yeah as a kid I never really got Niagara on the Lake but as an adult I love that little town. Some good pubs and great views!

There’s also the jetboat tour near there that takes you up to the whirlpool which is mad cool, definitely something a teenager would be interested in.

Niagara falls itself is neat but super touristy, Maid of the mist is fine, but in general I like Niagara on the Lake better.
