The entrance to the Cave of the Winds is inside Niagara Falls State Park.
When you're done experiencing the Cave of the Winds, you can take a stroll along the path inside the park to get a view of Horseshoe Falls.
If you visit Cave of the Winds in warmer months, you can get so close that you need to wear a poncho to protect yourself from getting drenched. During the cooler months, the platforms are removed so they can be protected from wear and tear. But now, a new, permanent deck allows visitors access to views like the one below.
The Buffalo Niagara area gets some harsh winters, so the platforms are removed, treated, and placed back for safe use during the summer months.
I'm an avid winter hiker and I've always loved seeing waterfalls of any kind in the winter more than in than the summer. The icicles, snow-covered trees, and frozen blue ice mounds make waterfalls that much more beautiful. If you can stand the cold, I highly recommend giving the winter experience a chance.
Visitors can spend as much time on the viewing deck as they like. From start to finish, the entire experience lasted about 30 minutes for me.
As the months go on, staff will add in more of the normal Cave of the Winds ramps before putting it all completely back together and allowing visitors full access to the falls. Don't worry, though – if you don't make it here this winter, it'll be available next winter, too.
