Although this was just posted recently, it is about a visit to Niagara Falls last winter.
From MySanAntonio.com:
… the highlight of our visit to Ontario was the trip to Niagara Falls, which is about 80 miles on Queen Elizabeth Way, or 90 minutes away.
The bus ride by City Sightseeing Toronto was comfortable and filled with places to see before and after the trip to Niagara Falls with friendly tourists from several countries.
But the anticipation of seeing the 180-foot Falls was all we could think about. Even the cold — about 15-20 degrees most days during our February trip – was not on our minds. We thought we were prepared for what we’d see, knowing the Falls area gets about 56 inches of snow a year and it doesn’t melt until spring.
Everything was white. Snow and ice covered everything we saw. The walkway from the bus parking lot to the lodge near the Falls was covered in snow, but it was not slippery. It’s well-tended and appears to be frequently salted or plowed.
The roar of the Falls is loud, with a tremendous amount of water flowing from Lake Ontario onto the Niagara River, but during the winter, portions of the Falls freeze, reducing the flow.
