Little Island in NYC is an architectural playground! This public park is located on pier 55, along the Hudson River (around 13th street). Once you enter it is full of hilly lush landscape and winding paths, taking you on a beautiful escape from the hustle & bustle of NYC. If you're there in the evenings it's a great spot to catch the sunset. There is a small amphitheater for performances, check Little Island's site for schedule and seasonal hours.
