Laurel Caverns

Laurel Caverns is the largest cave in the Commonwealth of Pennsylvania by volume and area. Located in the community of Farmington, it sits on the Chestnut Ridge near Uniontown, roughly 50 miles (80 km) southeast of Pittsburgh. Initially an unregulated wild cave that was known by locals and word of mouth as "Dulany's Cave" (alternate spelling: "Dulaney's Cave") during the early 1900s, it was owned, during the 1930s, by Norman Cale and his brother, and then later by Cale and his wife, Helen, who opened it to the general public as a show cave on July 1, 1964, and marketed it as "the caverns in the clouds". In 2025, Pennsylvania Gov. Josh Shapiro proposed turning Laurel Caverns into a state park. David and Lilian Cale, who created the Laurel Caverns Conservancy, then donated the property to the Commonwealth of Pennsylvania, and on April 6, 2026, Gov. Shapiro officially announced the grand opening of Laurel Caverns State Park. Laurel Caverns became Pennsylvania's 125th State Park, and its first underground.
