Greycliff Prairie Dog Town State Park

Greycliff Prairie Dog Town State Park is a protected area in southeastern Montana where black-tailed prairie dogs live in established colonies. The roughly 98-acre site contains multiple populations separated naturally by hills and valleys into distinct ward groups.

The park was established in 1974 through cooperation between Montana State Parks, the Nature Conservancy, and the Montana Department of Transportation to protect declining prairie dog populations. This effort marked an important recognition of the need to preserve these animals and their grassland habitats.

Interpretive signs throughout the park explain how prairie dogs organize themselves into social groups and support other wildlife in the grassland ecosystem. You can watch their interactions directly and learn why these animals matter for the health of the prairie.

The park is open year-round, but from November through April only walk-in access is available as vehicle parking closes during winter months. Parking areas and picnic tables are open during warmer seasons, making visits more comfortable outside the restricted period.

Unlike many other animals in the region that hibernate, the black-tailed prairie dogs here remain active and visible throughout the winter months. This makes the park an interesting observation spot even during the colder seasons.
