Visitors also are welcome to take a self-guided tour at any time during regular business hours, 8 a.m. to 4 p.m. weekdays.

Group tours and larger gatherings are invited to give advanced notice of their plans to visit so additional staff can be available and tours can be customized.

Tours can be scheduled anytime during business hours by calling 605-594-6511 or emailing the EROS Outreach office.  

The USGS science center is located approximately ten miles north of Sioux Falls, South Dakota. Free parking passes will be issued at the security checkpoint upon arrival. Click here for more visitor information.
