According to the 2010 census, the county has a total area of 411.32 square miles (1,065.3 km2), of which 394.51 square miles (1,021.8 km2) (or 95.91%) is land and 16.81 square miles (43.5 km2) (or 4.09%) is water. 
Monroe County is divided between the basins of the East Fork and West Fork of Indiana's White River.  The northern part drains to the West Fork; the southern part of the county drains to the East Fork, primarily via the Salt Creek and its tributaries, such as the Clear Creek (known as the "Jordan River" on Indiana University Bloomington campus).
Several artificial reservoirs have been constructed by damming the county's creeks. The largest of them is Lake Monroe, a large reservoir on the Salt Creek in the south-eastern part of the county. It is used both for recreational purposes and to supply the city with drinking water.  Until the late 1960s, the main source of water supply was the smaller Lake Lemon (constructed 1953), in the northeastern part of the county; now it is the backup water source, and is mainly used for recreation. 
The third largest[ vague] is Griffy Lake, on the northern slope of the county. Constructed in 1924 by damming Griffy Creek, it was Bloomington's main water source until 1954; it is now used primarily recreationally, although there are arrangements for it to be used as an emergency water source as well.    In 2012-2013, the lake was drained, the dam repaired, and then the lake was refilled again.
An even smaller Weimer (Wapehani) Lake in the Clear Creek basin was originally constructed for water supply purposes as well, but during most of its history was used purely for recreation (fishing).  In 2017, plans were announced to drain this lake permanently, as the authorities considered the dam unsafe.  This was carried out in the summer of 2018.
Limestone has been quarried in Monroe County since 1826.  A number of abandoned limestone quarries in the county are now cliff-surrounded lakes (seen in the 1979 film Breaking Away), stable without ongoing human intervention.

Form many years Monroe County was one of the most populous counties in the USA which did not contain any US highways or Interstate highways. However, in December 2015 the I-69 extension was completed into the county and this distinction disappeared. The highway was further extended north into Morgan County on September 18, 2018
Although Monroe County has a rich railway history, currently the only railway within Monroe County is the Indiana Rail Road, whose mainline crosses the county from the north-east to the south-west, with a few branches to local industrial facilities.    There is no passenger service.
Between 1854 and 2004, an important north-south line connecting the Ohio River with Lake Michigan crossed Monroe County as well, serving Stinesville, Elletsville, Bloomington, Smithville, and Harrodsburg. It was operated by the Monon Railroad throughout much of the 20th century, and later by CSX. The last passenger service operating on this line was Amtrak's Floridian Chicago-Miami service, during 1972-1979. With the termination of this service in 1979, Monroe County forever lost passenger railway service. CSX continued to use this line for freight for another quarter of a century, but in 2004, it stopped using this line. Large parts of it have since been converted to trails.  
- Monroe County Airport, located a few miles southwest of Bloomington. Scheduled passenger service to this airport was terminated ca. 1997, and since then the airport has been used by general aviation only.
