The hike is easy and educational. As you walk, you will get a guided nature tour of the nonprofit educational center’s two aquariums and eight outdoor ponds and learn about the winter habitats of the amphibians, reptiles and fish that call the hatchery home.

Admission is $6 for adults, $4 for seniors 65 and older. For more information, go to nwsdy.li/hikecsh or call 516-692-6768.
