3. The Alley Pond Adventure Course is the First Challenge Course in NYC

The Alley Pond Adventure course, a sprawling complex of low and high ropes, includes a zip-line, a climbing wall, a trust fall station and much more. It is the first challenge course in New York City and one of the largest in the country. (It’s also the largest challenge course in the metropolitan region.) Even so, the course remains under-the-radar to this day, nearly a decade after its construction.
