"Named after the great author from Hannibal, Missouri, Mark Twain National Forest sprawls for more than 1.5 million acres in the Ozark Highlands. The only national forest in Missouri, it’s a treasure trove of outdoor adventure, with 750 miles of trails for hiking, mountain biking, and horseback riding; 350 miles of perennial streams for canoeing, kayaking, and floating; several caves for exploring; and more than 35 campgrounds and picnic areas for relaxing in between activities. The Eleven Point National Scenic River is a particularly lovely area of the park, snaking through the Ozark hills along an underdeveloped, ruggedly beautiful shoreline."
