The Weldon Spring Site Interpretive Center offers a window to the past and demonstrates the U.S. Department of Energy’s commitment to the future. Exhibits address the history of the Weldon Spring area, the site’s contributions to World War II and the Cold War, cleanup, and continuing long-term stewardship. The interpretive center provides educational programs, tours, research opportunities, and meeting rooms for public use. The surrounding gardens, prairie, trails, and disposal cell viewing platform are open to the public to explore.

The 41-acre disposal cell is open to the public during daylight hours via a staircase and crushed gravel walkway. A viewing platform allows a panoramic view of St. Charles County and surrounding Howell Prairie.

The stairs to the top of the Weldon Spring Site Disposal Cell are now open.  

Visitors can once again climb the stairway to the top of the 75 feet high disposal cell, where they have a panoramic view of portions of both St. Charles and St. Louis counties. Visitors can also walk around the cell's perimeter or visit the Interpretive Center. The site is free and open to the public.
