No roads exist in the park. Rangers give guided hikes and prehistoric tool demonstrations, June 11 through Labor Day weekend. Educational programs are presented on- and off-site by appointment. There are no lodging or camping facilities in the park. An accessible boardwalk trail into the wetlands near the Visitor Center is available for disabled visitors and persons of all walking abilities. 

Effigy Mounds NM Adopts New Visitor Center Hours for Winter and

HARPERS FERRY, IA - Beginning Sunday, October 24, 2021 the Effigy Mounds National Monument Visitor Center will shift to winters hours; these hours, 9:00 a.m. to 4:00 p.m. central time, will remain in effect until May 29, 2022 (Memorial Day weekend).

In addition to shifting to winter hours, the park's visitor center will be experiencing a temporary shortage of staff during the coming months. The visitor center, as a consequence, will be closed at least two days per week, Thursdays and Fridays, beginning November 11, as well as during other brief periods when staff are not available.

Despite these seasonal changes, the public is invited to visit and enjoy the park and all hiking trails from dawn until dusk every day. For visitors' convenience, copies of the park brochure and trail map will be available in the breezeway outside the visitor center, where the north unit trails begin. Additionally, portable restrooms are provided in the parking lot for visitors' use.

When park managers know with sufficient notice that the visitor center will be closed on days other than Thursdays or Fridays, information will be posted on the park's website and Facebook page listed below. Staff also will post signs on the visitor center door.
