Big Bus Tours in New York (and many other locations) is one of the best ways to get a lay of the land, so I recommend making this one of the first activities you do! Big Bus uses open-top double-decker buses. With commentary in multiple languages, you can hop on and off at iconic landmarks. Big Bus has 2 routes (a blue and red route), so choose which bus you hope on depending on if you're exploring Downtown or Uptown!
