Smiths Falls Railway Museum of Eastern Ontario

Housed in a beautifully preserved former Canadian Northern Railway station, this museum traces the rail history of eastern Ontario with a solid collection of locomotives, rolling stock, and railway artifacts. What sets it apart is that you can actually spend the night in a caboose or hop on a train ride — it's far more hands-on than your typical museum. Great pick if you've got kids in tow or just a genuine soft spot for trains.
