The White Lake State Park is a state park and recreation area in Tamworth, New Hampshire. It features a National Natural Landmark, the 72-acre Pitch Pine Stand.

Preserved for the glacial lake known as the White Lake, the White Lake State Park is best known for being the best swimming beach in the White Mountains. The lake is created back in the Ice Age, where the depression was from the glacial ice that was buried beneath debris or glacial till. When the ice melted, the area turned into a great lake.

Equipped with a playground, showers, restrooms, dump stations, fire rings, and drinking water spots, the White Lake State Park is one of the best recreational areas around. It is ideal for swimming, boating, biking, picnicking, fishing, and camping.
