Getting there: The Black Hills Wild Horse Sanctuary (12163 Highland Road, Hot Springs, S.D.; 1-800-252-6652; www.wildmustangs.com) is about a 75-mile drive from Rapid City Regional Airport.
The tours: Between May 5 and Oct. 31, the sanctuary is open for tours from 8:30 a.m. to 6 p.m. daily. Two-hour group tours cost $50 for adults, $45 for ages 55 and older, $15 for ages 13-18, $7.50 for 5-12 and free for younger children. A private three-hour tour costs $150 per adult and $75 per child. The private six-hour tour costs $1,000 for as many as three people, including lunch. Also available is a private six-hour tour with a two-night cabin stay on the property for $1,500. Reservations are required for all tours. Costs of the private six-hour tours (and cabin stay) are considered donations and are therefore tax-deductible.
Other sights: The sanctuary is a short drive from Badlands National Park (35 miles to the gravel-road south entrance and 125 miles to the paved north entrance), Mount Rushmore (60 miles) and Deadwood (100 miles), among other notable South Dakota stops.
Seeing more: A documentary about Hyde and the sanctuary, "Running Wild: The Life of Dayton O. Hyde," is screening at film festivals this year. Monte Matheson no longer works at the sanctuary but makes a cameo in the film.
