A popular spot for getting wowed or soaked amid natural splendor, Niagara Falls attracts curious spectators and adventurous honeymooners from around the world. The splendid main attraction - more than six million feet of water cascading over a rocky crest - sits partially in the United States and partially in Canada. The U.S. side has recently been busy promoting other activities to lure visitors. Venues like the Aquarium of Niagara offer parents fun and engaging alternatives for kids, after or in between visits to the Falls. Outdoor recreation such as hiking, biking, fishing and camping can be found at the Niagara Falls State Park. The storied history of attempts to conquer the majestic Falls is captured at the Daredevil Museum; the Schoellkopf Museum concentrates on the history and geology. There's more to the Falls than, well, the Falls, including a wide array of dining and lodging options, from budget to upscale. This awe-inspiring region makes for an exhilarating and multi-faceted getaway
