Where is the walkway to Canada from Niagara Falls?

Nope, there is no walkway or pedestrian bridge that lets you walk directly from the U.S. side of Niagara Falls into Canada. The only way to cross is via the Rainbow Bridge, which is about a mile downstream from the falls. You can walk across it, but you'll need a passport or enhanced ID, and you'll pay a $1.00 toll (USD or CAD) per person on foot. It's a 10-15 minute walk with great views, but don't expect a scenic path right at the falls—it's a real border crossing with customs on both sides.

If you're staying on the U.S. side and just want to see Canada, the Rainbow Bridge is your only option for walking. Driving across the Rainbow, Whirlpool, or Lewiston-Queenston bridges is faster but costs $3.25-$5.00 USD in tolls. Honestly, unless you have a passport and really want Canadian side views or a cheap souvenir, the walk is fine, but it's not a "walkway to Canada" like a park path—it's a functional bridge with traffic and border guards.
