Lacawac, Historic estate and natural landmark in Wayne County, Pennsylvania.
Lacawac is a 461-acre property featuring a main house built in 1903 with cross gables and two-story porches, alongside five other original structures. The grounds contain a clear glacial lake that serves as the core of an active research station and nature preserve.
The estate was built in 1903 for a U.S. congressman in the Adirondack Great Camp style popular among wealthy landowners of that era. It became a non-profit organization in the 1960s to preserve the natural surroundings and support ecological research.
The property transformed from a private retreat into a community space focused on teaching people about freshwater ecosystems and conservation. Today, visitors experience how scientific study and environmental protection shape the way locals and researchers connect with the landscape.
The property offers guided tours and self-guided paths along the shoreline, making it accessible for visitors to explore the grounds at their own pace. Plan for a few hours to see both the historic buildings and the lake area without feeling rushed.
The lake preserves water from an ancient glacial event more than 13000 years in the past, making it a rare freshwater system in this region. Few places on the continent maintain such pristine conditions in a glacial lake at this southern latitude.
