It is the mission of the National Park Service to preserve the remnants of the historic route of 1804-1806 Corps of Discovery Expedition located along the Lewis and Clark National Historic Trail and to provide a comprehensive interpretation of its history, including the American Indian perspective, to allow for better visitor understanding and appreciation of its significance.
To support partners in their efforts to make good decisions, have quality programming, be proactive in their planning and to provide for visitor access to Trail resources, the Trail has developed the Partner Support Program or PSP. For more information on the Partner Support Program and how it could help your organization meet its needs along the Trail, please visit the Partner Support Program page.
