Established in 1914 as New Jersey's first state park, Swartswood is well known for its great fishing and tranquil surroundings. Little Swartswood and Swartswood Lake were formed by glaciers thousands of years ago and are now home to a variety of fish. Both lakes have been the focus of water quality improvement efforts including invasive aquatic weed control and watershed protection. Whether you are on land or water, there is always a chance you will catch a glimpse of the spectacular wildlife in Swartswood from bald eagles to the unique plant life found in our sinkhole ponds. The park is open year round with a variety of recreational activities available depending on the season. During the summer, colorful sailboats take to the water either on a leisurely sail around the lake or while participating in the sailing regattas scheduled throughout the season.
