Students attended a brick building at 425 N. Third Street, known as Albert Gross School, which housed kindergarten through grade 12.

The school continued as a K-9 facility until 1966, when the district was consolidated with the Pleasant Valley School District; at that time, high school-aged students from LeClaire began attending Pleasant Valley.

Tugfest is an annual three-day-long event in early August in which a rope is stretched across the Mississippi River from LeClaire, Iowa to Port Byron, Illinois.

LeClaire offers some of the best bald eagle photography opportunities in the continental US at Lock and Dam 14 on the Mississippi River.
