Franklin Lakes Nature Preserve

Franklin Lakes Nature Preserve is a protected natural area in New Jersey containing wetlands, woodlands, and meadows alongside a former reservoir. The landscape offers diverse habitats within a compact setting that invites walking exploration.

The land became a reservoir in 1919 when Molly Ann Brook was dammed and later transitioned to protected status in 2011. This change reflects a shift in how the land was valued and used.

The preserve serves as an educational center where visitors learn about environmental conservation through organized programs and direct observation of local ecosystems.

The preserve is accessible from two entry points: the main entrance on High Mountain Road with parking and a pedestrian entrance on Ewing Avenue. Visitors should wear appropriate footwear since the terrain varies from wet to dry areas.

The site displays volcanic basalt formations roughly 200 million years old that are visible along the former reservoir shoreline. These geological features offer a window into the ancient past of the region.
