In 2018, America is celebrating the 50th anniversary of the National Trails System Act as well as the Wild and Scenic Rivers Act. The 1968 National Trails System Act created and protected trails that celebrate outdoor adventure, such as the Appalachian Trail and trails that allow us to walk through history, such as the Selma to Montgomery National Historic Trail.

To celebrate this anniversary, on the America’s National Parks Podcast we’re sharing with you a two-part episode following one of our National Historic Trails — The Journey of Lewis and Clark’s Corps of Discovery from 1804 to 1806 in their quest to explore the newly expanded United States, and search for a route to the Pacific Ocean.
