To walk across the Rainbow Bridge (connecting Niagara Falls, NY, to Niagara Falls, ON), the best parking options are on the American side near the Niagara Falls State Park. You can use State Park Lot 1 (near the Prospect Point Observation Tower) or Lot 2 (on Goat Island), both of which are a short, scenic walk to the pedestrian entrance. On the Canadian side, the most convenient parking is the Rainbow Bridge Parking Lot at 4348 Hiram Street, located just steps from the bridge entrance and the Bird Kingdom attraction. In 2026, the Casino Niagara Parking Garage is also a popular choice for those looking for covered, secure parking directly across from the bridge. Remember that walking across the bridge costs a small toll (typically $1.00 USD/CAD for pedestrians) and requires a valid passport or travel document, as you will be passing through international customs and immigration during your walk.
