The Eleven Point River is beautiful and flows through the heart of the Ozarks, carving a scenic path past dolomite bluffs, deep pools, and spring-fed tributaries—including Greer Spring, which doubles its volume and transforms it into a cold-water haven for trout. Designated in 1968 as one of the original National Wild and Scenic Rivers, its 44-mile protected stretch offers solitude and Class I-II paddling, making it a popular spot for anglers, canoeists, and nature lovers.

Greer Springs Recreation Area features a short, shaded trail that descends to Missouri’s second-largest spring, where 220 million gallons of icy water surge daily from a cave and underground aquifer. The hike winds through old-growth hardwoods and pines, with dogwoods, sassafras, and impressive rock formations lining the canyon, making it a favorite for photographers and nature lovers. While the spring itself is off-limits for fishing or wading, Greer Crossing offers campsites, picnic areas, and river access for paddling and trout fishing along the Eleven Point National Scenic River.

The Big Spring Spur branches off the Between the Rivers Section of the OT that runs just over seven miles through quiet forest and rocky creek beds. Though moderately challenging, the trail provides access to Big Spring—the largest freshwater spring in North America. Navigation can be tricky due to sparse blazes and overgrown stretches, so an offline komoot GPS route or detailed map is a good idea. Additionally, the trail also leads to Big Springs Lodge and campground, which makes the detour well worth the trek if you're looking for an overnight stay during a long hike.
