The South Branch Root River is a scenic waterway in southeastern Minnesota's Driftless Area. Originating in western Fillmore County, it flows eastward for approximately 40 miles before joining the main stem of the Root River just downstream of Lanesboro. The river carves through a landscape of towering limestone bluffs and verdant valleys. Paddlers can enjoy several distinct sections, each offering its own character.

The upper reaches from Carimona to Preston feature a narrow, canopied channel with delightful riffles and standing waves. This 7-mile stretch is popular among anglers, as it's stocked annually with brown trout. The next 14-mile segment from Preston to Lanesboro continues the engaging paddling experience through state forest land, passing the Eagle Bluff Environmental Learning Center. The river's difficulty ranges from Class I to II, making it suitable for beginner to intermediate paddlers. Riffles and small rapids provide excitement, while calmer pools allow for relaxed floating. Spring and early summer typically offer the best water levels, though the river is often paddleable into fall.

The South Branch's corridor supports a diverse ecosystem. Paddlers may spot bald eagles, herons, and various songbirds. The surrounding bluffs showcase oak-hickory forests and limestone outcroppings characteristic of the Driftless Area.

Key access points include Highway 12 bridge in Carimona, Preston Trailhead Park, and Lanesboro. These charming small towns offer amenities and serve as gateways to the river experience. Lanesboro, in particular, is known for its quaint downtown and connection to the Root River State Trail.

For those seeking a multi-day adventure, it's possible to continue past the confluence onto the main Root River, potentially extending the trip all the way to the Mississippi River near La Crosse, Wisconsin. This longer journey would cover approximately 60-70 miles.

Paddlers should be aware of potential strainers and swift water, especially after heavy rains. Life jackets are required by law. The river's popularity for tubing and fishing means paddlers should be prepared to share the water, particularly on summer weekends.

The South Branch Root River offers a quintessential Driftless Area paddling experience, combining natural beauty, gentle whitewater, and access to charming river towns.
