Calhoun County is a narrow finger of mostly high ground located between the Mississippi River and the Illinois River. It is serviced by two state operated free ferry boats crossing the Illinois River (the Brussels Ferry and the Kampsville ferry) and two privately operated toll ferry boats crossing the Mississippi River into Missouri (the Winfield ferry and the Golden Eagle ferry). There is also one bridge that spans the Illinois River at Hardin as well as land routes to the north into bordering Pike County.

The county had many prosperous farms and orchards at a time when transportation was mainly by river. It is very popular with sight seers in the fall due to the natural beauty of the Illinois River valley and its proximity to the Great River Road. Calhoun county was added to St. Louis Metropolitan Statistical Area in 2003 along with Bond and Macoupin counties in Illinois, and in Missouri, Washington County.
