You’re coasting. No cars. No sirens. Just the rhythmic click-clack of your bike’s derailleur and the sound of the Root River tea-colored water rushing over limestone rocks to your left. Minnesota has a lot of "rail-to-trail" projects—it’s kinda our thing—but the Root River State Trail hits different. It isn’t just a paved path through the woods. It’s a 42-mile vein that pumps life into the Driftless Area, a weird, beautiful chunk of the Midwest that the glaciers somehow forgot to flatten.
Honestly, if you haven’t spent a Saturday morning between Fountain and Lanesboro, you’re missing out on the most dramatic descent in the state. Most people think Minnesota is flat. Those people haven't biked the "Big Hill" out of Fountain.
The Geography of the Driftless
What makes this trail special is the dirt. Or rather, the lack of it in some places. We’re talking about the Driftless Area. During the last ice age, the glaciers bypassed this specific corner of Southeast Minnesota, Western Wisconsin, and Northeast Iowa. Because the ice didn't grind everything down, you get these massive limestone bluffs and deep, craggy valleys.
The Root River State Trail follows an abandoned Milwaukee Road railroad bed. Because trains aren't great at climbing vertical walls, the trail stays relatively level, even though it’s surrounded by 300-foot cliffs. It’s a bit of a topographical cheat code. You get the mountain views without the mountain lungs.
Most riders start in Fountain. Why? Because it’s the highest point. You basically get a seven-mile gravity-assisted ride down into the valley floor. It’s glorious. You’ll pass through deep rock cuts where the air temperature suddenly drops ten degrees. It feels like walking into a walk-in cooler on a July afternoon.
The Town-Hopping Magic
One of the coolest things about this trail is the spacing. You’re never more than a few miles from a slice of pie or a cold beer.

- Fountain: The "Sinkhole Capital of the USA." Not even kidding. There are thousands of them in the county.
- Lanesboro: The crown jewel. It’s been named one of the "Prettiest Towns in America" by about a dozen magazines. It has no stoplights. No chain stores. Just a massive dam, a professional theater (Commonweal), and a lot of ice cream.
- Whalan: Stop here. You have to. There’s a tiny stand called the Whalan Depot that sells world-class pie. The rhubarb is legendary.
- Peterson and Rushford: These towns feel a bit more "real world" and less "tourist postcard," which is a nice change of pace. Peterson has a great museum in an old train depot.
The Logistics: What You Actually Need to Know
You don't need a special permit to ride the Root River State Trail. It’s free. That’s a win. But don't just show up with a rusty Huffy and a single bottle of lukewarm Dasani.
First, the wind. It usually blows from the west. If you start in Rushford and head toward Fountain, you are fighting gravity and the breeze. That’s a bad day. Always check the weather vane.
Second, the surface. It’s paved. Smooth enough for skinny road tires, but wide enough for the family trailers and the e-bikes that are increasingly taking over the path. Speaking of e-bikes, Minnesota law generally allows Class 1 and Class 2 e-bikes on state trails, but keep it under 20 mph. Nobody likes a speed demon on a narrow bridge.
Wildlife and the "Rattlesnake" Rumors
Yes, there are timber rattlesnakes in the bluffs. No, they aren't waiting to jump you at the trailhead. They are shy, endangered, and honestly, you’d be incredibly lucky (or unlucky, depending on your vibe) to see one. They like the sunny rock ledges way above the trail. What you will see are bald eagles. Dozens of them. They follow the river looking for a fish dinner. You’ll also likely see wild turkeys, white-tailed deer, and the occasional turtle sunning itself on the asphalt.
The Seasonal Shift
Summer is the peak, obviously. Lanesboro turns into a bit of a zoo on holiday weekends. If you hate crowds, go on a Tuesday. Or better yet, go in early October. The maple trees in the valley turn a violent shade of orange and red that looks fake. It’s so bright it almost hurts your eyes.

The trail is technically open in the winter for cross-country skiing, but it isn't always groomed. It’s more of a "do it at your own risk" situation once the snow flies. If you’re hiking, stay off the ski tracks. It’s a cardinal sin in Minnesota.
Beyond the Bike: The River Connection
Don't forget the water. The Root River itself is a "lazy" river, meaning it’s perfect for tubing and canoeing. A popular move is to bike from Lanesboro to Whalan, then rent a canoe and float back. Several outfitters in Lanesboro (like Root River Outfitters) handle the shuttles.
The river is also a blue-ribbon trout stream. If you’re into fly fishing, the North Branch and the Main Stem have some of the best brown trout fishing in the Midwest. You’ll see guys in waders standing under the bridges. They know something you don't.
Hidden Gems and Misconceptions
People think the trail ends at Houston. It does, but there’s a gap between the Root River State Trail and the Harmony-Preston Valley State Trail. They are two different segments that connect. If you add the Harmony-Preston branch, you’re adding another 18 miles of scenery, including some pretty intense climbs up out of the river valley.
One thing people get wrong: they think the trail is "easy" because it's a rail-trail. While the grade is mostly 1% or 2%, the sheer distance can sneak up on you. If you ride from Fountain to Houston and back, you’ve just done a metric century (about 84 miles). That’s a lot of saddle time.

Also, the "Sinkhole Capital" thing isn't just a marketing gimmick. The limestone (karst) topography means the ground is literally like Swiss cheese. If you look off the trail in the woods near Fountain, you’ll see giant depressions in the earth where the roof of a cave collapsed. It’s cool, but maybe don't go wandering off-trail without looking where you step.
Actionable Tips for Your Trip
If you’re planning a hit-and-run day trip or a full weekend, here is the brass tacks advice from someone who has ridden this loop twenty times.
- Parking Strategy: If it’s a busy weekend, don't even try to park in downtown Lanesboro. Go to the trailhead in Isinours (the junction where the Harmony trail splits) or park in Preston. It’s quieter and you’ll find a spot instantly.
- The Food Situation: Pedal Pushers in Lanesboro has the best burgers, but the wait can be an hour. If you’re starving, the Aroma Pie Shop in Whalan has savory pot pies too, not just the sweet stuff.
- Phone Service: It’s spotty. Once you get deep into the valley between Peterson and Houston, your bars will disappear. Download your maps for offline use. You won't get lost on the trail, but if you need to call a shuttle, you might be walking a mile to find a signal.
- Gear Check: Bring a light jacket even in summer. The valley floor stays damp and shaded, and those rock cuts are legitimately cold.
- Water: There are pumps at most trailheads, but they are sometimes shut off for maintenance. Carry two bottles.
The Root River State Trail isn't just a path; it's the heartbeat of the Driftless. It’s where the agricultural plains of the Midwest finally give up and turn into something rugged and wild. Whether you're there for the 18% grade "Big Hill" or just a slice of rhubarb pie, it’s the kind of place that makes you forget your phone exists for a few hours.
Check your tire pressure. Pack an extra tube. Start in Fountain so you can coast. Just make sure you leave enough time to sit by the dam in Lanesboro and watch the water move. That’s the real point of the trip anyway.
Next Steps for Your Adventure
- Check the DNR Map: Go to the Minnesota Department of Natural Resources website and download the official GeoPDF map. It works with GPS on your phone even when you don't have cell service.
- Book Your Stay Early: If you want a B&B in Lanesboro for a Saturday night in September, you need to book it three months in advance. Minimum.
- Inspect Your Brakes: If you’re doing the descent from Fountain to Isinours, you’ll be riding your brakes for a solid fifteen minutes. Make sure your pads aren't worn down to the metal.
