Portsmouth/Yawkey: South Drag Line+Haul Road

To view the ride route map and elevation please scroll to the bottom of this page.

Cuyuna.com Trail Ride Overview:

An "extended" 5.2 mile loop for a beginner to intermediate mountain biker. Starting and ending at the Croft Mine Historical parking lot just north of the City of Crosby, on MN HWY 6.

Currently you do not need a Minnesota State Park vehicle permit to park in the Croft Mine Historical parking lot.

This loop starts on the paved Cuyuna Lakes State Paved Trail heading west across HWY 6 from the parking area and then leading into both segments of South Drag Line trail, continuing again east across HWY 6, and experiencing the full loop of the Haul Road singletrack trail.

These two trails feature Cuyuna's more appropriate flow and elevation for the first-time cyclist.

The Portsmouth Mine Lake adjacent to the Cuyuna Lakes State Trail is Minnesota's deepest, inland lake at 450 feet deep. Sagamore is also world-famous for the launch of the space program Man High II (click for more info on this famous space flight).

Depending on the speed you cycle, this could be a couple of hours, or a full day experience. 

The Cuyuna Lakes State Paved Trail is a two-way, two-direction trail. The Cuyuna Lakes Mountain Bike Trails per this ride loop are a one-way, one-direction loop.

            Responsible riding: International Mountain Bicycling Association (IMBA) Rules of the Trail


            Respect the landscape

            • Respect your local trail builders and be a good steward of the physical environment. Keep singletrack single by staying on the trail. Practice Leave No Trace Principles. Do not ride muddy trails because it causes rutting, widening and maintenance headaches. Ride through standing water, not around it. Ride (or walk) technical features, not around them.


            Share the trail

            • Most of the trails we ride are multi-use. Mountain bikers yield to foot traffic, and descending cyclists yield to climbing cyclists. Be nice. Say hi.

              Ride open, legal trails

              • Poaching trails, building illegal singletrack or adding unauthorized trail features are detrimental to our access of the Cuyuna Country State Recreation Area. Poorly-built features could also seriously injure other trail users. If you believe there aren’t enough trails or variety near you, it's time to get involved. Your engagement will be welcomed because it takes a village to create, enhance and protect great places to ride. Please visit the Cuyuna Lakes Mountain Bike Crew's website.

                Ride in control

                • Speed, inattentiveness and rudeness are the primary sources of trail conflict among user groups. If you need to pass, slow down, ring a bell or verbally announce yourself, and wait until the other trail user is out of the path. Be extra aware when riding trails with poor sight lines and blind corners, and make sure you can hear what's going on around you by not wearing personal earphones when mountain biking or trail running.

                  Plan ahead

                  • Be prepared and self-sufficient. Every mountain biker should carry what they need for the ride they're undertaking, and know how to fix a flat tire and make minor repairs. Download a GPS trail app on your phone for navigation or carry a map in unfamiliar locations. Ride with a partner or share your riding plan with someone if you’re heading out solo.

                    Mind the animals

                    • When it comes to wildlife, live and let live. If you encounter wildlife, please let the wildlife be, and remain exactly where it was found.


                      • If you want to ride with your dog, they must be on leash no longer than six feet in length. Be prepared to take care of your dog. Ensure your companion is obedient enough to not cause problems for you, other trail users or wild animals.
