The town of Cumberland Gap, Tennessee is located inside of the park's territory.
The Cumberland Gap Visitor Center is located on U.S. Highway 25E just southeast of the city of Middlesboro, Kentucky, and just northwest of the Cumberland Gap Tunnel and the town of Cumberland Gap, Tennessee.

Hydrology.
The park contains over of streams. With the exception of one, Little Yellow Creek, all of these originate from within the park, with those to the north of the main ridge flowing into the Cumberland River, and those to the south flowing into the Powell River. Overall water quality in the park is good to fair, with some areas falling below recommended pH levels, likely due to natural causes, and others exceeding recommended levels of microorganisms, possibly due to contamination from campgrounds.
Ecology.
The area of the park is 97% forested and contains 970 species of vascular plants, 90 of which are classified as sensitive or rare species. These include 108 non-native species of plants, and 31 considered to be highly aggressive invasive plants.
The park is home to at least 145 species of birds, and 40 species of mammals, including the near-threatened bat, "Myotis sodalis" (Indiana bat). The streams in the park house around 27 species of fish, including "Chrosomus cumberlandensis" (blackside dace), federally listed as an endangered species. Additionally, surveys have identified at least 36 species of reptiles and amphibians.
Ecosystems in the park are threatened by a number of insect infestations from non-native pest species, including "Dendroctonus frontalis" (southern pine beetle), and "Adelges tsugae" (hemlock woolly adelgid). The species "Agrilus planipennis" (emerald ash borer) and "Lymantria dispar dispar" (gypsy moth) also represent imminent threats from surrounding areas.
History.
Business leaders from Middlesboro, Kentucky meeting in Cincinnati for the Appalachian Logging Conference, proposed a Lincoln National Park, centered around Fern Lake as early as 1922. However, two bills introduced into the Kentucky State Legislature the following year by State Congressman John Robison both failed. Later attempts in 1929 sought to create memorials for Civil War battles fought in the area, and also failed. In 1938, the National Park Service agreed to support a park if the lands were donated to form one, and the Cumberland Gap National Historical Park Association was created, sparking more unsuccessful attempts in Kentucky, and then passage of a bill in Virginia in 1939 that paved the way for federal authorization.
The park was established on June 11, 1940 by Franklin Roosevelt in order to "commemorate the story of the first doorway of the west". It was authorized by Congress to occupy an area not to exceed . The surrounding states purchased and deeded the land of the park to the federal government in 1955, and the official opening took place in 1959.
In 1992 the park purchased the area surrounding Gap Cave, which had previously been privately owned. By 1996, the park had undergone some $280 million in improvements, including construction of the Cumberland Gap Tunnel.
Toward the southern end of the park lies Fern Lake, created by an earthen dam in 1890, which provides water to the nearby town of Middlesboro, Kentucky. The area surrounding the lake was purchased by the park in four phases following the passage of the Fern Lake Conservation and Recreation Act, increasing the overall size of the park by 20%:
As of 2010 there were plans to acquire an additional of land surrounding the lake. As of 2018 the park had an estimated $15 million in deferred maintenance.
