White Lake Natural Resource Area

Call Directions Website

White Lake Natural Resource Area White Lake offers opportunities for hiking, boating, fishing, and wildlife observation. White Lake itself is a deep 69-acre spring fed water body.

The White Lake Natural Resource Area is a 394 acre preserve in Hardwick Township owned by the County of Warren. Beneath the clear blue water lays a chalky marl bottom composed of freshwater mollusk shells and clay. A variety of habitats surround the lake, including fertile meadows, karst limestone exposures, sinkhole ponds, and stands of mature hemlock and hardwood forests. The shoreline is also home to various endangered or threatened plant species. In addition, the preserve is dotted with several cultural and historical points of interest, including a lime kiln and the stone wall remnants of an ice house/marl processing facility.

- Please stay on the marked trails and do not disturb marked sensitive habitats.
- Please remove and carry out any trash.
- Hunting is only allowed by special permit.
- Removal of plants, animals, wood, stone, or other natural materials is prohibited.
- Gasoline powered boats, motorized vehicles such as ATVs, and alcoholic beverages are prohibited.

FYI - Trail Update! - We are currently undertaking measures to clear downed trees along the Ridge & Valley trail (close to where it meets the Blue trail) on the eastern side of the park. These trees came down due to the strong storms leading up to July 4th. We feel confident that should have the trail completely open by noon tomorrow. (see attached photo of area undergoing tree work) - check back for details!
