There are currently five public schools operating as part of the Edmonson County School System. They are Kyrock Elementary (in the Kyrock community in northern Edmonson County), South Edmonson Elementary (near the Chalybeate community in southern Edmonson County), the Edmonson County Fifth/Sixth Grade Center, Edmonson County Middle School, and Edmonson County High School (all in Brownsville).

There are two main routes that form the major transportation corridors through Edmonson County.

KY 70 is the primary west to east route, traversing the width of the county.

KY 259 enters Edmonson County at the border with Grayson County, near the town of Bee Spring. The highway continues on, bridging the Green River (the only bridge over the river in Edmonson County), before intersecting with KY 101. KY 259 then branches off in a southeastern direction while KY 101 continues as the main north–south route through the county, exiting into Warren County just south of the community of Chalybeate.

Additionally, KY 185 is a north–south route connecting Bowling Green with locations in the western part of the county and points north into Grayson County. I-65 passes through the southeastern tip of the county, but has no interchanges allowing access to the freeway within the county. I-65 parallels the older US 31W, which runs through a small southeastern portion of the county.

The biggest tourist attraction in Edmonson County is Mammoth Cave National Park, which usually draws almost 2 million visitors a year. The park includes in its area roughly a fourth of the county.

Located mostly in the northern part of Edmonson County, the Nolin Lake area was incorporated as a Kentucky State Park in 1996. The lake itself was created following the 1963 impounding of the Nolin River and construction of Nolin Dam. The lake offers fishing and other recreational opportunities.
