Fort Abraham Lincoln State Park

The Fort Abraham Lincoln State Park, the oldest state park in North Dakota, provides visitors with a diverse historical landscape. The site houses the On-A-Slant Mandan Indian Village which was established in the 16th century and remained inhabited until 1781.

At its peak, the village was home to 1,000 members of the Mandan Tribe who lived in 86 earth lodges, some of which have been reconstructed for visitors to experience today. In addition, Fort Abraham Lincoln, which housed lieutenant colonel George Armstrong Custer and approximately 500 troops, can be visited on the site.

Today the fort consists of a collection of original and rebuilt structures such as the barracks and the fort’s makeshift theater which visitors can tour daily. Visit our website for more information about the visitor center, tours, camping, and equestrian and hiking activity in the state park.
