Catch tons of wildlife while hiking around a 20 acre wetlands that is the main attraction of the Binghamton University Nature Preserve.
Park across from the Nature Preserve Kiosk where you can pay to park ($1 for 30 mins) ask an attendant for directions at the entrance of the university for ease of navigation through campus. The lot is clearly marked however and is titled 'Lot M0'
Follow trail markers to hike around the Marsh and Harpur Pond for a solid 1-2 hour trip. See wildlife just about everywhere you turn, but be careful of some animals can be very friendly with humans. You'll be in Bearcat Nation, so don't be surprised if you run into a few students escaping from their studies. Sunsets over the wetlands also make for good photo opportunities.
