There are no bicycle trails, or use of bicycles on the Monument's hiking and walking trails. High impact recreational activity is limited at the Monument due to the sacred nature of the site.
Traveling by bicycle to Effigy Mounds can be dangerous; please use extreme caution on the three mile approaches to the visitor center along HWY 76. There are absolutely no shoulders as you ride this road that hugs closely to a railroad track on the Mississippi River side and 400 ft sheer limestone bluff faces on the other.
Agricultural semi-trucks often cannot contain their speed while trying to negotiate the steep downgrade on the approach from Harpers Ferry, IA.
Along the approach from Marquette, it is often a trick for motor vehicle operators to avoid hitting each other near the center line, especially when trying to avoid large chunks of limestone that frequently fall from the bluff face.
