Fort Mandan Nature and History Trail

NRT Logo


The Fort Mandan Nature and History Trail is located at the replica of Fort Mandan, Lewis and Clark’s wintering post of 1804-05, along the Missouri River, west of Washburn, ND. The loop trail is comprised of fly-ash and cement, mixed to form a natural-looking, yet hard surface to accommodate wheelchair traffic. The trail guides walkers through the riparian forest of cottonwood trees, along the bank of the Missouri River.

Filled with wildlife including whitetail deer, pheasants, turkeys, Canadian Geese and Bald Eagles, the Nature Trail provides a pristine environment for those enjoying the Fort Mandan replica, which includes the Headwaters Fort Mandan Visitor Center and Fahlgren Park, with picnic shelters and a playground area. The trail is a partnership between the Lewis and Clark Fort Mandan Foundation and many donors, including members of the energy industry, ND National Guard, and ND Parks and Recreation.
