The Cold Spring Harbor Fish Hatchery is an engaging, educational destination that works perfectly for a Chol Hamoed family outing. This non-profit environmental center is home to the largest living collection of New York State freshwater reptiles, fish, and amphibians. Visitors can spend a relaxed afternoon exploring the two aquarium buildings and walking among the eight outdoor ponds. Interactive activities like feeding the trout or trying out the "Catch & Keep" fishing offer hands-on fun for all ages. It’s a spacious, outdoor-friendly spot that provides a unique way to enjoy the holiday weather while discovering local wildlife.
