Custer State Park is one of the oldest and largest state parks in the United States.
Custer State Park covers 71,000 acres of the Black Hills in South Dakota, featuring granite spires and rolling grasslands. It is home to a free-roaming herd of approximately 1,300 American bison, one of the largest publicly owned herds in the world. The park's Wildlife Loop Road provides consistent sightings of bison, pronghorn, elk, and wild burros. The Needles Highway traverses jagged granite rock formations and includes tunnels carved through narrow rock needles. Sylvan Lake, formed by the damming of Sunday Gulch Creek, serves as the primary recreational hub for swimming and paddle sports. The park contains multiple historic lodges, including the State Game Lodge which has hosted various U.S. presidents. It is a critical habitat for mountain goats and bighorn sheep. The park operates under the management of the South Dakota Department of Game, Fish and Parks. It is situated within a region characterized by a high concentration of granite outcroppings known as the Needles.
