Located just north of the Missouri River east of I-64 is the quaint community that is Weldon Spring. It was first established in the late 19th century, with its post office popping up in 1875 and staying in operation until 1957. One of the biggest nearby attractions is the Nuclear Waste Adventure Trail. Officially named “The Weldon Spring Site Interpretive Center,” this site is home to the 75-foot-high Weldon Spring Disposal Cell, which entombs 1.48 million cubic yards of radioactive and contaminated materials. Today, you can climb this perfectly safe tourist attraction for a sprawling view of the entire Weldon Spring area.
Much of the area is devoted to residential spaces filled with vast estates and comfortable ranch homes alike. Residents here make great use of the numerous walking trails, the impressive greens at Whitmoor Country Club, and the plentiful amenities of nearby Chesterfield, Cottleville, and Howell.
