For the second year in a row the popular Summer of Thrills is back. Starting today you’ll see two free spectacular thrilling acts take place on the Victoria Avenue promenade atop Clifton Hill.

One act sees a death –defying act atop a high wire which is strung between Tussauds Wax Museum and the Days Inn. Daredevil Hans Winn will ride a motorcycle across the wire and his sister Natalie will be hanging beneath the motorcycle.

Another act takes place atop the 10 storey Imperial Hotel. A large revolving wheel will have a performer walking within and outside the wheel.

The show take place Thursday through Mondays at 2 p.m.,4 p.m.,6 p.m. and 8 p.m.

There’s never a dull moment in Niagara Falls.
