Overview
Tucked away in a beautiful park setting along the Little Lehigh Creek, the Li’l-Le-Hi Trout Nursery in Allentown, Pennsylvania, is a favorite local destination for families, field trips, and anyone looking for an easy, fun outdoor experience. With bubbling streams, shaded pathways, and thousands of hungry trout just waiting to be fed, it’s an amazing place for all ages. This fish hatchery offers a unique peek into Pennsylvania’s fish stocking efforts and makes for a relaxing visit full of kids’ activities, wildlife, and scenic views in the Lehigh Valley.
The Li’l-Le-Hi Trout Nursery was established in 1883, making it one of the oldest continuously operating trout nurseries in the United States. Today, it’s a public park operated by the City of Allentown, in cooperation with the Pennsylvania Fish & Boat Commission, and with support from dedicated volunteers often referred to as the “elite squad.” Over the decades, Pennsylvania legislators have supported funding to ensure the hatchery remains a model of education and conservation. Trout raised here are used to stock streams throughout the state, helping to maintain fish populations in a controlled environment for both environmental balance and recreational fishing.
