"Even if you’re not necessarily into nerding out about flying buttresses and the beaux-arts style, The Architectural Boat Tour is still one of the most unique ways to see the city. For an hour and half, you’ll learn some history, see some great views of the buildings and the changing colors of the leaves, plus every boat has a bar if you’re in the mood for a drink. Tickets and departure times can be found here." - john ringor
