Things To Do



Wide open spaces, the hard-working cowboy, his spirited cow pony, and vast herds of cattle are among the strongest symbols of the American West. Once the headquarters of a 10 million acre cattle empire, Grant-Kohrs Ranch National Historic Site is a working cattle ranch that preserves these symbols and commemorates the role of cattlemen in American history. Encompassing 1,600 acres, over 80 historic structures, many historic artifacts, and walking trails, there is something for everybody to do at the ranch. Stop at the visitor center to pick up a park brochure, sign up for guided tours of the main ranch house, and find out what other programs are being offered. Through museum collection pieces and virtual tours of the ranch the history of cattle ranching in the American West comes to life. In addition to regular summer programs, the park hosts many special events throughout the year.

  • Hiking

    There are also a number of easy walking trails to explore. Take a walk down the nature trail that follows Cottonwood Creek to the Clark Fork River and see some excellent grassland habitat. You can follow the old Milwaukee Railroad right-of-way that will take you to a swampy area which is great for spotting aquatic birds. Or maybe you would rather head out to the far pastures to see the main herd of cattle and experience some incredible views along the way. Whichever trail you decide, it is a great opportunity to get out and stretch your legs and visit parts of the ranch that most visitors never experience.
