Take a hike to Taughannock Falls, Cascadilla Gorge or any of the 100-plus waterfalls in Ithaca. Swimming is open at three different waterfalls in the area!
Stroll the Downtown Ithaca Commons, a pedestrian mall that's the heart of the city's vibrant social scene. There are lots of restaurants (Viva, Mia, and Thompson and Bleecker - happens to also be the couple's favorite street corner in NYC) and late night bars (Moonies) to check out.
Collegetown Bagels (great sandwiches), Ithaca Beer Co (downtown location has a great outdoor space), and Boatyard (on the water!)
Enjoy a Finger Lakes wine tasting experience on the Cayuga Lake Wine Trail, the nation's first wine trail.
Experience the quaint charm of the city that invented the first ice cream sundae. Check out Cornell Dairy or Purity. Fun Fact: Cornell Dairy's ice cream cannot be sold in stores as the fat content is too high and it would be considered butter!
Go boating on Cayuga Lake. Rent kayaks at Paddle-N-More in Lansing or Puddledockers in Ithaca, or learn about the Finger Lake's history and ecology in educational cruises with Discover Cayuga Lake.
