Medicine Rocks State Park is a 330-acre site at 3,379 feet in southeastern Montana known for its Swiss cheese-textured sandstone formations, many carrying thousands of centuries-old inscriptions. Theodore Roosevelt called it "as fantastically beautiful a place as I have ever seen." It is listed on the National Register of Historic Places and was historically a gathering place for Indian hunting parties. The park has eight first-come campsites and one reservable group-use site, with fire rings, vault toilets, drinking water, and a picnic shelter. Visitors can hike, bike, picnic, photograph, and watch wildlife such as mule deer, antelope, Woodhouse's toads, and sharp-tailed grouse. Pets are welcome. The park is open year-round, with day use hours of 7 a.m. to 10 p.m. and camping available all year.
