Managed by the USDA Forest Service, the 25,000 square-foot building includes the permanent exhibit hall, 158-seat theater, an education room for hands-on curriculum-based activities, and a retail store. The center is accessible and offers parking for tour buses and recreational vehicles. Service animals (guide dogs, signal dogs, or any other animal individually trained to provide assistance to an individual with a disability) may be used within the Lewis and Clark Interpretive center. Our Mission "The Lewis and Clark National Historic Trail Interpretive Center imparts to the public a personal sense of President Thomas Jefferson's vision of expanding America to the west; it inspires awe and awakens curiosity toward the challenges faced by the expedition as they portaged the great falls of the Missouri River and explored the 'unknown'; brings to life the daily experiences of the expedition and the environment and native peoples of the 'uncharted West'; and celebrates the indomitable spirit of human discovery we all share."
