Park on the gravel "pull-off" West-bound on Route 434 in Apalachin (See pin). Walk along the fence and turn into the opening where you'll go through a tunnel about 20 yards long. From there you're in the preserve where you can hike the yellow trail, leading to the Bird Blind and other scenic overlooks of the marsh. Spot birds of prey, cranes, finches, and other wildlife. The loop with stopping to observe wildlife will take about an 1.5 hours. A nice short escape.

Stick around or come in the late evening to catch an awesome sunset over the marsh.
