The Cuyuna Lakes mountain bike trails close at 6 a.m. Friday, November 6, for firearms deer season. They stay closed through Sunday, November 22, and reopen Monday, November 23, according to the Cuyuna Lakes MTB trail closure calendar. When they reopen, the deciding factor won't be the calendar. Once real snow arrives in Crosby and Ironton, volunteer groomers decide when each trail is ready to ride, and the grooming that follows a snowfall closes the singletrack to bikes before it opens it.
That changes the routine. A snow day is for snowshoes, and the morning after grooming is for fat bikes. One Saturday in early December puts the whole winter season in front of the town at once.
Seventeen Days Off, Then a Different Rulebook
The closure is an annual November event. The trail crew describes it as a way "to keep everyone safe" during rifle and firearms deer season. The posted window runs from 6:00 a.m. on November 6 through 11:59 p.m. on November 22.
Until then, the trails are in shoulder-season mode. The crew asks riders to stay off when surfaces are wet, soft or muddy and to ride only when the ground is firm or frozen solid. Water services at the trails have already been shut off for winter. On days the trails are open during hunting season, the crew's advice is to wear blaze orange or bright colors, use lights at dawn and dusk, ring a bell or call out near hunters, and leave the Bluetooth speaker at home.
Daily status changes quickly this time of year. The crew points riders to Trailbot for updates and conditions.
What the Cone Actually Means
The winter rules are written for snow. In its Cuyuna Country State Recreation Area trail guidance, the Minnesota DNR says volunteers generally groom in the afternoon or evening after snowfall ends. They mark recently groomed trails with an orange cone at the trail entrance.
The cone closes the trail to bikes. Freshly groomed snow is soft and easily damaged until it refreezes, so the trail closes to biking right after grooming but stays open to snowshoeing and skiing. Bikes are allowed back the first morning after grooming. Even then, the DNR says it usually takes 12 to 24 hours before the surface is ideal for riding.
In practice, the day snow falls is rarely the day to ride. The trail is typically groomed that afternoon or evening once the snow stops and is closed to bikes overnight. It opens to riders the next morning and often rides best a full day after that.
Two DNR details explain why the rule is enforced the way it is:
- Ruts count as damage. If your tires leave ruts in groomed trail, the DNR treats that as damage, and the trail is closed to that activity.
- Snowshoes help bikes. Snowshoeing and skiing pack down freshly groomed or soft trails, which can get bikes back on sooner. The DNR suggests bringing snowshoes or skis as a backup, especially on days above freezing.
Who Gets Which Trail Once Snow Falls
The DNR lists about 40 miles of packed winter trails at Cuyuna Country. They don't all follow the same rules. Here's how the main trail types differ for the uses most people in town care about.
| Trail type | Bikes | Other uses | Notes |
|---|---|---|---|
| Groomed singletrack and Sagamore Unit trails | Tires at least 3.7 inches wide | Foot travel on skis or snowshoes only | No pets on groomed trails |
| Snowmobile trail inside the recreation area | No biking December 1 to April 1 | Snowmobiling on designated trails | Bike ban is seasonal |
| Paved Cuyuna Lakes State Trail | No winter restrictions | No winter restrictions for hiking | Groomed and paved |
The groomed singletrack is the most restricted of the three. Walking in boots isn't allowed there, pets aren't allowed on any groomed trail, and a fat bike with tires under 3.7 inches doesn't qualify. The paved Cuyuna Lakes State Trail has no winter restrictions on hiking or biking. That makes it the simplest option for a walk or an easy ride when the singletrack is soft or freshly groomed.
Parking narrows down in winter too. The DNR plows Miner's Mountain Rally Center, Croft Trailhead, Sagamore Trailhead, and Yawkey Road and the yurt parking.
For setup, the DNR suggests 2 to 4 psi in soft snow and up to 8 psi on firm snow, studded tires when conditions vary, and a check of the Crosby forecast before heading out.
December 5 Puts the Trails and the Holiday Party on One Saturday
The first big test of the winter rules lands on Saturday, December 5. That day also brings Crosby's largest holiday gathering, so the ride fills the morning and the party takes the afternoon.
- Morning, Intergalactic Fat Bike Day. The trail crew, Otso, Red Raven and Wolf Tooth are hosting a Global Fat Bike Day event that starts and ends at Red Raven, 2 3rd Avenue Southwest in Crosby. It's free, and registration is required. The posted schedule has a rider meeting at 9:30 a.m. and departure at 10 a.m. Riders return to Red Raven between 11 a.m. and 1 p.m., and the event wraps up at 2 p.m. The group rides together through the Yawkey Unit on a route that stays close to town, so riders can peel off early, and the event page calls it "a social ride, not a race." Groomed trails depend on snowfall, or as the organizers put it, "If the snow gods deliver, expect groomed winter trail goodness." Back at Red Raven, there will be a Wolf Tooth Components giveaway, event merch, hot drinks and food. Fat bike rentals will be available through Red Raven.
- 3 to 6 p.m., Cuyuna Christmas/Snow Many Smiles. On June 8, the Crosby City Council took up CRMC's annual special-event application for that Saturday afternoon. Under the plan, CRMC provides food, water, portable toilets and garbage collection, and the city provides the band shell, cook shack and power.
On the posted schedules, the ride wraps up before the holiday event begins, so riders can make both.
Last year's lineup shows what the afternoon tends to look like. The Brainerd Dispatch previewed the 2025 event as free and family-friendly at Crosby Memorial Park. It listed The District, hot cocoa, soup, popcorn, kids' games, a petting zoo, fire dancers, Build-A-Bear, Santa and Mrs. Claus, and fireworks over Serpent Lake. CRMC sets the program each year, so the 2026 details may differ.
Where to Warm Up on Main Street
Crosby's warm-up spots are a short ride from the trails, and several sit right on Main Street.
Red Raven, the Fat Bike Day host, serves house-roasted coffee, food and local beer and also handles bike rentals. Its winter e-fat-bike rentals are picked up at the same 2 3rd Avenue Southwest address.
Iron Range Eatery, at 6 W Main St, serves American comfort food with a full bar and craft cocktails. It lists hours of 11 a.m. to 8:30 p.m. Sunday through Thursday and 11 a.m. to 9 p.m. Friday and Saturday. That's late enough to get there after a ride that ends at dark.
Cuyuna Brewing Company is at 1 East Main Street. Its new Vault lounge is open to the public during select curated hours.
In Ironton, The Hudson Smokehouse at 208 Curtis Ave describes itself as two blocks off the trail. Seasonal hours vary around town, so check before you leave the trailhead.
