This 44‑mile Mammoth Spring Loop ride begins at Mammoth Spring State Park, home to Arkansas’s largest spring and a designated National Natural Landmark. The route moves through quiet Ozarks backroads with a smooth mix of rolling hills, shaded stretches, and easy curves that give the ride a relaxed, scenic rhythm. The combination of rural countryside and the spring’s striking turquoise water at the start gives the loop a calm, inviting character that makes it an enjoyable run for riders of any pace.
