Are you ready to visit the Weldon Spring Site? Although the interpretive center has been closed to in-person visits since 2020, we are open to the public via virtual programs. We’re here to support your STEM curriculum at all grade levels and are ready to connect you with experts in many fields. Our interpreters have been hard at work creating and presenting programming for schools, community groups, and the public — all in a virtual environment.  Contact us at or 636-300-2601 to set up your virtual program.

At the Weldon Spring Site, we welcome you to hike along the Hamburg trail and enjoy the native plant gardens with outdoor benches and picnic tables. While the stairs to the top of the disposal cell are closed for repair, the pathway surrounding it is still open. 

We will continue to update our communications, if anything changes in the status of our interpretive center, and we look forward to the time when we can safely welcome our visitors back inside. We ask that guests follow the updated federal guidance related to social distancing, provided by the Centers for Disease Control and Prevention.

See you (virtually!),
The Weldon Spring Site Team
