Mountain bike trails at Cuyuna Country SRA



The 30-mile long mountain bike trail system covers nearly 800 acres inside the Cuyuna Country State Recreation Area (CCSRA), and has been ranked as a Silver level ride center.

With over 30 purpose-built routes to choose from, everyone from beginner to pro can enjoy exciting rides and overlooks. Check out the Yawkey Mine Lake, or for a great view, go west through the Miner's Mountain Rally Center to see the Miner's Mountain Overlook and the Huntington Mine Lake. The trails are enhanced by the deep-red soil, turquoise mine lakes, and white bark of the aspen and birch trees. Watch for bald eagles, red-tailed hawks, beavers and other wildlife.

When it rains, the single track trails will be immediately closed to all users (foot or bike) until trail conditions dry out or improve.

Hiking is allowed on the mountain bike trails, unless posted restricted. Hikers follow the same rules as bikers. Follow all signage and only travel trails in their intended direction. Leashed pets are allowed but must be personally attended at all times. No exceptions!

Extreme caution should be used on the mountain bike trails at all times! The State of Minnesota does not assume responsibility for injuries.

  • The CCSRA is not always staffed. Be prepared to take care of yourself in any emergency or equipment failure. 
  • Mountain bike trails can have loose and slippery surfaces. Proceed carefully as rocks and trees frequently fall, and are commonly encountered along the trails.
  • Full face helmets, full-length gloves, biking armor and a full suspension bike are recommended.
  • Do not ride alone. Give other trail users enough space.
  • Maintain control on the ground and in the air. Clear the landing area quickly after a jump.
  • Hunting is an allowed activity in the CCSRA. Trails close to all uses other than hunting during the three week firearms deer hunt in November. More about hunts in state parks and recreation areas.
  • Trail markers are shown on the map and placed in the field. If you have an emergency, call 911 and provide the dispatcher with the following: 1) Description of the emergency. 2) Number on the nearest trail marker. 3) Name of the trail you are on.
  • The skills development area contains numerous technical features (ramps, jumps, etc.) that vary in difficulty and change frequently due to weather and usage. Pay attention to the difficulty ratings and stay in control. Your speed will determine your risk of injury.

Trail closures

When it rains (or snows, if the ground is not frozen), the single track trails will be immediately closed to all users (foot or bike) until trail conditions dry out and firm up. Trails typically reopen a few hours after rain ends, but the cooler the temperature, the longer this may take. Wet, soft or muddy trails are extremely easy to damage, which is why we close them until they dry out. If you are leaving tire ruts or footprints in the trail or your bike or footwear is muddy, you are damaging a trail that is currently too soft to use.

Exception: Sagamore Unit trails do not close under wet weather conditions.

All trails in the CCSRA close to all uses (foot or bike) for three weeks in November for the firearms deer hunt.

Prohibited uses
  • Off-highway vehicles.
  • Camping in non-designated areas.
  • Riding or hiking on soft, wet, muddy or closed trails.
  • Consuming or displaying intoxicating liquors.
  • Building a fire, except in a fire ring at the campground or yurts. 
  • Target and trap shooting.
  • Horse riding on mountain bike trails.
  • Off-leash dogs or other pets. Pets must be on a leash no longer than six feet and personally attended at all times -- no leaving dogs in the vehicle while you ride. 
    • Pets and hikers are not allowed on Jump Line Trails or on trails or technical features in the Mountain Bike Skills Development Area.
  • Any activity that causes damage to the trail surface, either by foot or bike.
  • Rock collecting.
  • "Free riding" into the landscape, leaving defined trail surfaces, or unauthorized building or modification of trails and/or technical features.
  • See additional rules.

Winter trail grooming:

Volunteers generally groom trails in the afternoon or evening after snowfall ends, and mark recently groomed trails with an orange cone at the trail entrance. Freshly groomed trails are very soft and easily damaged until they can refreeze and firm up. For this reason, trails close to biking immediately after they have been groomed, but are open to snowshoeing and skiing. Trails reopen to biking the first morning after they have been groomed, but it usually takes 48 hours before surface conditions are ideal for biking again.

Winter tips:

  • If you are leaving tire ruts in groomed trails, that is considered damage and the trails are closed to that activity.
  • Bring snowshoes or skis as a backup activity in case trail conditions are too soft for biking. (Most days when temperatures are above freezing.) Snowshoeing and skiing help pack the surface on freshly groomed or soft trails, which can get bikes back on the trail sooner.
  • Reduce tire pressure in your bike. 2-4 psi in soft snow; up to 8 psi in firm snow.
  • Use studded tires for variable trail conditions and added safety.
  • Check the Crosby, MN weather before you travel (ZIP 56455).
