Use the Goat Island entrance instead.

Yes, the Goat Island entrance to Niagara Falls State Park is usually less crowded than the main Prospect Point one. Prospect Point funnels everyone to the visitor center, the Maid of the Mist ticket booth, and the observation tower. Goat Island is a quieter entry that drops you right by the American Falls and Bridal Veil Falls with a short walk. Parking can be easier too, though check ahead—Goat Island access is sometimes restricted during peak season or events. Your first stop should be Goat Island, not Prospect Point.
