Yes, Niagara Falls is consistently one of the most visited natural attractions in North America, attracting over 15 million people annually. Crowds peak significantly during the summer months (July and August) and on major holiday weekends like Canada Day (July 1st) and Independence Day (July 4th). During these times, wait times for popular attractions like the Maid of the Mist or Journey Behind the Falls can exceed 90 minutes, and hotel rates in "falls-view" properties can skyrocket. To avoid the heaviest congestion, the best time to visit is during the shoulder seasons of May or September. In September specifically, the weather remains warm, all attractions are still operational, but the post-Labor Day crowd drop-off results in wait times decreasing by as much as 60%. If you visit in the winter (November to January), you will experience the "Winter Festival of Lights" with minimal crowds, though some outdoor boat tours will be closed due to ice and freezing conditions.
