The Ultimate Guide to Cuyuna Country State Recreation Area: Biking, Lakes & Camping

Imagine standing on a ridge of deep red earth, looking out over water so clear and turquoise it could pass for a tropical lagoon—except this is central Minnesota. Decades ago, these hills and pits were the heart of an active iron ore mining operation on the Cuyuna Range. When the mines closed more than 30 years ago, nature and thoughtful planning stepped in. What remained was transformed into the Cuyuna Country State Recreation Area (Wikipedia), a roughly 5,000-acre outdoor playground near the towns of Crosby and Ironton that now ranks among the Midwest’s premier destinations for mountain biking, paddling, camping, and year-round adventure.

The landscape still carries the unmistakable signature of its industrial past: striking red dirt trails, white aspen forests, and a network of flooded mine pits that form crystal-clear lakes. Visitors quickly notice the rusty red soil that coats bike tires, shoes, and sometimes even clothing—an iron-rich hallmark that gives the trails their distinctive character and the area its “Shred the Red” nickname. Cuyuna Country State Recreation Area delivers world-class singletrack, excellent water recreation, unique lodging options, and a welcoming vibe that rewards both first-timers and seasoned outdoor enthusiasts.

World-Class Mountain Biking

Cuyuna mountain biking is the main draw for many visitors. The trail system within Cuyuna Country State Recreation Area and the surrounding Cuyuna Lakes network offers over 50 miles of purpose-built singletrack (local trail organizations and community sources often cite closer to 70 miles when including connected trails), earning it recognition as an IMBA Silver Level Ride Center. The trails weave through red dirt, aspen stands, and past the turquoise mine lakes, creating a riding experience that feels both technical and scenic.

The system is designed for a wide range of abilities. Beginners find flowy green trails and skills areas, intermediate riders enjoy rolling terrain with berms and rollers, and advanced and expert riders seek out steeper gravity-oriented lines, rock features, and jumps. Trail names often nod to the mining history—think Drag Line, Haul Road, Galloping Goose, or Sledgehammer—adding a layer of local character.

Trail Units

The recreation area is organized into distinct units that help riders plan their day. Key areas include the Sagamore, Mahnomen, Portsmouth, and Yawkey units. The Miner’s Mountain Rally Center near Ironton serves as a popular central hub with parking, trail access, skills features, and an overlook offering sweeping views of the red hills and lakes.

The North Mahnomen Unit stands out for more advanced riders. It features gravity flow trails connected by routes such as Backcountry, with options that include rock drops, technical gardens, and larger features suited to experienced cyclists seeking a sense of remoteness. The Sagamore Unit includes adaptive mountain bike trails built with gentler grades and fewer obstacles, making them accessible for riders using adaptive equipment as well as families and beginners looking for a more relaxed experience. Portsmouth and Yawkey units offer a mix of trails that loop near the campground and yurts, allowing convenient ride-in, ride-out access for overnight guests.

Trail maps are available through the Minnesota DNR and local organizations such as the Cuyuna Lakes Mountain Bike Crew. Many riders use apps like Trailforks for navigation and real-time updates. Always ride within your ability, wear a helmet, and yield appropriately—mountain bikers typically yield to hikers where trails are shared, though the singletrack is primarily managed for bikes.

The Red Dirt Experience

The iron-rich soil that gives Cuyuna its signature look also influences how the trails handle weather. The red dirt can be grippy and fast when dry, but it is vulnerable to damage when wet. A critical local rule protects the trails: singletrack closes during active rainfall and typically remains closed until conditions improve. Most trails reopen about one to two hours after rain stops, though some sections (such as certain connector or heavier-use trails) may need additional drying time—sometimes up to 24 hours after heavy rain. Riding wet or muddy trails creates ruts that are difficult and time-consuming for volunteers to repair. Check current conditions via the Cuyuna Lakes Mountain Bike Crew resources or Trailbot before heading out. This simple respect for the “rain rule” keeps the red dirt trails in top shape for everyone.

Riders often leave with red-stained tires and a sense of having experienced something uniquely Minnesota. The combination of purpose-built flow, scenic overlooks, and that distinctive soil creates a memorable day on the bike whether you ride a short loop or link multiple units for a bigger adventure.

Beyond the Bike: Lakes and Water Activities

Cuyuna Country State Recreation Area is defined as much by water as by dirt. The landscape contains roughly 16 pristine mine lakes formed when abandoned open-pit iron mines filled with groundwater, plus additional natural lakes. These waters are known for exceptional clarity—visibility often ranges from 30 to 60 feet—creating the striking turquoise color that contrasts beautifully with the surrounding red soil and green forests. Shorelines total around 25 miles of largely undeveloped edge, offering quiet paddling and wildlife viewing opportunities (bald eagles, loons, beavers, and other species are commonly sighted).

Paddling & Scuba Diving

Kayaking, canoeing, and paddleboarding are popular ways to explore the mine lakes. Several accesses allow easy launching, and the calm, clear water is ideal for both beginners and experienced paddlers. Local outfitters can provide rentals if you don’t bring your own gear. The same water clarity that makes surface recreation appealing also elevates Cuyuna as a premier inland scuba diving destination in the Midwest. Divers encounter submerged mine features—shafts, foundations, roadbeds, and sheer walls—along with fish and occasionally loons. Depths reach several hundred feet in places (Mahnomen Mine Lake is reported around 525 feet, with Portsmouth among the deeper inland lakes). Dive operators in the broader region offer guided trips and site information for various skill levels. Always follow local regulations and safety practices for diving in these unique environments.

Trout Fishing

Several of the mine lakes are managed for trout. Anglers with a valid Minnesota fishing license and trout stamp can target rainbow and brown trout (along with other species such as bass, northern pike, crappie, and sunfish) in designated waters including lakes associated with the Portsmouth and Yawkey areas. The DNR stocks significant numbers of trout annually. Shore fishing, boat access, and the clear water all contribute to a productive and scenic experience. Check current regulations, seasons, and special rules on the Minnesota DNR website before fishing, as management can include specific limits or gear requirements for trout lakes.

Swimming is also permitted and popular at designated beaches, including areas near Portsmouth Campground and the Rally Center. The clear water and scenic setting make a post-ride or post-paddle swim especially inviting on warm days.

Camping and Lodging

Staying overnight at or near Cuyuna Country State Recreation Area lets you maximize trail time and wake up to the red dirt and turquoise lakes.

Portsmouth Campground

Portsmouth Campground sits on the northwest shore of Portsmouth Mine Lake and serves as the primary drive-in camping option within the recreation area. It typically offers around 33 campsites, with a portion (commonly listed as 18) providing electric hookups. Sites include a mix of shaded and more open grassy options. Amenities support a comfortable stay, with access to restrooms, showers (seasonal), a swimming beach, and direct connections to mountain bike trails for convenient ride-out mornings. A group camp that can accommodate larger parties is also available. Reservations are strongly recommended and can be made through the Minnesota DNR reservation system. The campground operates seasonally (generally spring through fall) and is not open in winter.

Unique Stays

For a more distinctive experience, three year-round yurts are available in the Yawkey Unit along Yawkey Mine Lake. These insulated canvas structures feature wood floors, woodstoves (with free firewood provided in winter), and basic furnishings that sleep up to seven people. They offer a private, immersive setting with ride-in/ride-out trail access. Note that yurts lack electricity and indoor plumbing (vault toilets are nearby), and rules prohibit pets, cooking, and open flames inside the structures. Outdoor picnic tables and fire rings support meal preparation. Yurts are popular and often book well in advance—reservations open through the DNR system.

Nearby private options expand the choices. True North Base Camp offers glamping-style stays, while accommodations in Crosby (such as loft-style or boutique lodging) provide comfortable bases close to town amenities and trail access points. Combining a night or two in a yurt or at Portsmouth with time exploring Crosby and Ironton creates a well-rounded trip.
