Yes, you are allowed to bring your camera, but doing so comes with a significant risk of water damage. The Maid of the Mist boat tour takes passengers directly into the dense spray zone of the Horseshoe Falls, where the environment is equivalent to a heavy rainstorm. While the tour provides a souvenir poncho, it will not protect a camera from the pervasive mist. If you choose to bring a camera, it is highly recommended to use a dedicated waterproof housing, a specialized rain sleeve, or a dry bag. Many visitors opt for waterproof action cameras (like a GoPro) or modern water-resistant smartphones kept in a sealed plastic pouch.
