Visitor information

Visitors should check in at the Yates Administration Building.

The Sanford Underground Research Facility does not currently provide regular public tours. However, the Homestake Visitor Center at 60 West Main Street (at the Open Cut) does offer trolley tours of Lead. Those tours include a drive through our surface campus and a guided visit to the Yates Shaft hoist toom. Trolley tours are available May through December. For more information, contact the Lead Chamber of Commerce at 605 584-3110. 

Other visitors to the Sanford Lab—including scientists, contractors, teachers, students and other guests—must make appointments or other arrangements in advance. Call (605) 722-8650 for more information.

A visitor's first stop is the reception desk at the Yates Administration Building at 630 E. Summit St. in Lead, S.D. Reception is open from 7:00 a.m. to 4:00 p.m., Monday through Friday. Visitors must have a valid driver’s license or other government-issued photo identification. Non-U.S. citizens must present a Permanent Resident Card or a valid passport. Visitors are issued badges, which they must wear conspicuously while at the Sanford Lab. (If you have a scheduled appointment at the Sanford Lab, please allow time to sign in and get a badge.) Visitors must return their badges when they sign out.

Visitors also must agree to follow all safety regulations at the Sanford Lab. The speed limit throughout the property is 15mph. The entire Sanford Lab—surface and underground, indoors and out—is a smoke-free facility.
