The Mountain Bike Capital of the Midwest

CAMBA Mountain Bike Trail System - Singletrack Capital of the Midwest

Welcome to the premier system of mountain bike trails in the Midwest, located in and around the beautiful Chequamegon National Forest region of Northwest Wisconsin.

The Chequamegon Area Mountain Bike Association off-road bike trail system consists of over 300 miles of marked and mapped routes through a near-wilderness area of striking beauty and peaceful solitude. The CAMBA system is quickly becoming the Singletrack Mecca of the Midwest, with more singletrack trail being constructed every year. CAMBA's vision of a linked system of singletrack trails connecting Hayward, Seeley, Cable and Namakagon was achieved in 2016. Additional enhancements and improvements to our world-class trail system continue to be implemented to provide the best possible mountain biking experience.

BREAKING NEWS: April 28, 2017

Additional Limited Trail Openings

We have the OK from the National Forest and Bayfield County Forest to open the trails on Saturday, April 29. This pertains to trails in Cable and Namakagon only, in addition to Mt. Ashwabay which has already opened. The crazy weather of late has played havoc with making the call on this. As of noon Friday the trees were still coated with ice and then raining ice balls.
The good news is that the frost is out of the ground and the solid precipitation when melted drained quickly. Please continue to use good judgement when riding.
And enjoy it while you can. Snow and cold are predicted again on Sunday afternoon into Monday. The trails will be closed until after the next snowfall has melted and the trails have dried out. Watch the CAMBA website for updates.
Note: We do not have approval yet from Sawyer County Forest to open the trails: Hayward and Seeley Clusters, so please do not ride Hatchery, Makwa, Seeley Pass or FlowMama Trails.


CAMBA Workday – Saturday, April 29

CAMBA will hold its Spring Workday on Saturday, April 29.  We expect the trails to just about be open by that date and most pre-season work on the trails will have been completed.

We have an assortment of projects to tackle in the Hayward area to including: mowing Hayward Hospital Trail corridor, repair boardwalk on Hatchery Creek Trail, bike park clean-up and tread work, assemble features in the bike park skills area, and leaf blowing.

Meet at the lower parking lot at Hatchery Creek Park at 9:00 a.m.  We will work til about 12:30. CAMBA will provide lunch and beverages following our work.  Please contact CAMBA if you have any special dietary needs.

Dress for outdoor work, bring work gloves, water and snacks.  If you have any questions, please contact CAMBA at or 715/798-3599.


The Borah Epic is a major fund raiser for the CAMBA trails and annually contributes up to $20,000 to CAMBA’s trail fund. The Epic is still in need of quite a few volunteers for the June 3 event. All kinds of tasks are available. There is a very easy sign-up process. Just go to and select a task that interests you.  Task descriptions detail time, place and the work to be done.

CAMBA strongly encourages you pitch in on the Epic.  This is a unique event run entirely on CAMBA singletrack and a great opportunity to showcase the CAMBA trails.

If you have specific questions, contact the Epic race director Jack Zabrowski or call 608/381-1033.

Ashwabay Trails Open

The Bayfield County Forestry Department has given the OK to open the CAMBA mountain bike trails at Mt. Ashwabay. Note that at this time these are the only trails open.

Also note that there is active logging on Hot Saw, and that trail remains closed.

Rain is predicted for this weekend, so factor that into your decision to ride and if conditions are wet, please do not ride.

Other trail openings will be announced as conditions warrant and as we get the go-ahead from the land managers.


CAMBA Women's Mountain Bike Weekend
June 9-11, 2017



Mt. Ashwabay Trails are open, except for Hot Saw where there is active logging. That should be finished soon
All other trails are  closed until the Forest Service and County Forests announce openings, which weather permitting, are traditionally May 1 - May 15, but could be earlier if conditions allow.
Gravel roads are not be affected by this closure. 


Please note the following special circumstances:

Makwa Trail - just north of Gravel Pit Rd. Trailhead is rerouted around the water crossing.

Hatchery Creek Bike Park is closed until spring.
The bike park was constructed with a high percentage of clay-based soil.  This is unlike most of our other trails. As such, it remains wet and soft longer that our sandy loam based soils.  It is potentially vulnerable to damage, so please help us preserve this new facility by not riding when wet. 



Please exercise good judgment when deciding to ride during periods of wet weather. Many of the trails will soak up the precipitation right away and it shouldn’t be an issue, but local conditions may vary. We appreciate your cooperation, understanding, and concern for the trails.
Ride safe, have fun & enjoy the great trails and forests we are so lucky to have.




After considerable debate and deliberation the CAMBA board of directors has voted to withdraw from the IMBA Chapter Program.  CAMBA became an IMBA chapter in 2012 very early in the development of the chapter program. Over time it has become apparent that CAMBA, as a mature and well developed trail advocacy organization, does not experience the same level of needs as other smaller and younger clubs and associations around the country and was not realizing a commensurate return on our revenue sharing arrangement with IMBA.

“CAMBA still believes in and supports the IMBA mission,” notes CAMBA executive director Ron Bergin.  “We fully intend to continue our support for IMBA into the future.”

CAMBA is obligated by our chapter charter agreement to continue to function as a chapter through a 60-day notice period that will expire in early May.  Until that time current members may receive renewal notices from IMBA and membership revenue will continue to be shared with IMBA.  CAMBA will roll out its own membership program in early May. CAMBA members with questions about their membership should contact CAMBA directly at or (715)798-3599.

IMBA has experienced a number of setbacks in recent months, precipitated by the loss of Subaru as a major sponsor as well as other sponsors.  This has required numerous cutbacks in the organization, as well as to services offered through the chapter program.  The Associate Regional Directors have been eliminated leaving only a few Regional Directors nationwide to assist local chapters.  The widely appreciated IMBA Trail Care Crews are also gone. 

When CAMBA became a chapter in 2012, a key feature of the program was the cost savings possible by obtaining group liability insurance coverage for CAMBA through IMBA.  The new program offers no help with liability insurance to chapters.

Central to the decision to withdraw from the chapter program has been the revenue share structure. Upon becoming a chapter, CAMBA agreed to share membership revenue with IMBA on a 60%-IMBA/40%-CAMBA basis.  As CAMBA developed its 2017 budget it became quite apparent that this percentage of membership revenue could play an important role in meeting our local needs. “We have several significant initiatives underway for the 2017 season,” relates Bergin, “and these additional funds will help us balance our budget.”

Extensive efforts have been made and are continuing to be considered by IMBA to rework the function and offerings of the chapter program. To date none of the new offerings of the second and third iterations of the chapter program provide sufficient incentive for CAMBA to continue in the program.  As previously noted, CAMBA thoroughly believes in and supports IMBA’s mission to create, enhance and protect great places to ride mountain bikes.  CAMBA will continue to play a role as a strong regional trail advocacy organization and assist IMBA in any way possible.

We look forward to your continued support as CAMBA returns to its roots as an independent trail advocacy organization working for you, the rider, to advocate for and to provide, maintain and keep improving our great system of mountain bike trails.
