The Largest Forest in Missouri: Mark Twain National Forest
Missouri is a state that boasts natural wonders, and Mark Twain National Forest is the crown jewel among them. Spanning across southern and central Missouri, Mark Twain National Forest is the largest forest in Missouri, offering a diverse range of landscapes, from the rocky glades of the southwest to the rolling hills of the St. Francois Mountains in the southeast.
This natural wonder covers a vast expanse of more than 1.5 million acres. It is the only national forest in the state.
A unique blend of natural wonders, including nationally-recognized streams, caves, ancient volcanic mountains, and large permanent springs, characterizes this one-of-a-kind wilderness.
Nestled mostly in the Ozark Highlands, it is a haven for nature enthusiasts and outdoor adventurers alike. Its unique beauty is made even more exceptional by the presence of the largest assemblage of “first magnitude” springs in the world.
Greer Spring, in particular, is renowned for its beauty and pristine waters. It is considered the most scenic spring in the entire state of Missouri.

Where Is Mark Twain National Forest Located on a Map?
Mark Twain National Forest is located in the mainly rural region of Missouri referred to as the Ozarks. Its 1.5 million acres of public land cover 29 counties. Sections of the forest are within one hour’s drive away from St. Louis, Springfield, Columbia, and Branson.
History of Mark Twain National Forest
The Mark Twain National Forest has a rich and unique history that has led to its creation as the magnificent wilderness area it is today.
The forest was once home to various Native American communities, including the Osage, Illini, Missouria, and Chickisaw, who lived in harmony with the natural world before the arrival of European settlers. Despite the rough terrain, which made farming difficult, the forest attracted pioneers during the nation’s westward expansion, who were drawn to the area’s natural resources.
The Mark Twain National Forest has seen many changes, including intense logging in the late 1800s and early 1900s. By the 1920s, the lumber mills that had once thrived in southern Missouri had vanished, and the result was widespread depletion of the region’s hickory, pine, and oak forests. This decline was the outcome of citizens harvesting these forests for lumber during the 1870s.
As the effects of intensive logging became more apparent in the 1920s and 1930s, the people of Missouri began to express growing concern about the state of abandoned and idle lands in the region.

Conservation Efforts
Between 1934 and 1935, eight separate purchase units were established, covering a total of 3,313,705 acres across 28 counties. And so, the conservation efforts bore fruit, as Franklin Roosevelt, the President of the U.S. at the time, declared the creation of Mark Twain National Forest in 1939, encompassing four of the purchased units, while the remaining four units became Clark National Forest.
This was a pivotal moment in the history of the forest, as it officially became a protected space for wildlife and recreation and a symbol of the state’s commitment to preserving its natural heritage for future generations.
On February 17, 1976, the Mark Twain National Forest was merged with the Clark National Forest, creating the massive expanse you can see today.
