What indoor activities are at Niagara Falls?

Yes, there are solid indoor options, but don't expect a theme park. The big one is the Niagara Parks Power Station, which is a massive, newly renovated hydroelectric plant turned museum. It's legitimately cool—you walk through the old generators, see a light-and-sound show in the cavernous turbine hall, and can take a glass elevator down to the actual base of the falls. Tickets are about $30 CAD per adult, and it takes 1.5-2 hours. Way better than the tourist traps.

Skip the Clifton Hill "indoor attractions" like the wax museums or the haunted houses unless you have a specific love for overpriced, dated kitsch. If it's pouring rain, the Fallsview Casino is your best bet for a few hours of cheap drinks and slots, but it's not a family activity. For a free option, head to the Niagara Falls History Museum downtown—it's small, costs $8, and gives you the real story behind the stunts and the daredevils without the circus vibe.
