Sunfish Pond is a 44-acre (18 ha) glacial lake surrounded by a 258-acre (104 ha) hardwood forest located on the Kittatinny Ridge within Worthington State Forest, adjacent to the Delaware Water Gap National Recreation Area in Warren County, New Jersey.

[2] The land was purchased by Charles C. Worthington who used the forest as a deer hunting preserve; the lake supplied water to his mansion.

[4] Supreme Court Justice William O. Douglas mentioned the lake in his dissenting opinion in the Sierra Club v. Morton case.

The shortest distance to the lake is 1.2 miles from the Douglas trailhead on Old Mine Road via the Garvey Springs Trail.

There is a Leave No Trace campground a quarter mile away, but proper food precautions must be followed since black bears are active in the area.
