History

The Central Idaho Mountain Bike Association (CIMBA) was created in 1997 by a small group of mountain bikers who wanted to ride together, work to improve trails, and create new riding opportunities in the area. As the popularity and value of those activities grew, so did CIMBA’s membership. CIMBA became an IMBA club and hosted several Trail Care Crew visits. The trailbuilding knowledge from those events is now evident by the improved trails in the region. CIMBA’s efforts helped create many new trails in the area including those at Bear Basin, Jug Mountain and Tamarack Resort.

In 2009, CIMBA was established as a 501c3 non-profit. Since that time it’s focus has grown to include educating user groups on safe cycling practices, developing land and user codes of conduct. Protecting resources with responsible usage standards, and engaging and educating our members in current policy issues relating to mountain bike and trail access.

The original emphasis on trails is still in place, and CIMBA is working with regional Forest Service offices and private land managers to maintain and create better riding opportunities.

Public Notice: Trail Grant Applications

The Central Idaho Mountain Bike Association (CIMBA) is preparing grant applications to the Idaho Department of Parks and Recreation for two separate funding programs: the Recreational Trails Program (RTP) and the Idaho Mountain Bike License Plate Fund. Public comments are requested to be submitted with both applications.

Recreational Trails Program – Central Idaho Trail Project

CIMBA is applying for a 2026 Idaho Department of Parks and Recreation Recreational Trails Program Grant to support trail maintenance and stewardship efforts across multiple trail systems in Central Idaho. The application will request funding to support ongoing maintenance on existing trails within the Bear Basin area, including segments such as Westies, Ditch Witch, Goose Creek, Upper and Lower Drains, Sleepy Hollow, the Brundage to Bear Basin Trail, and the Blackwell Lake Trail.

The Idaho Department of Parks and Recreation administers the Recreational Trails Program, a federally funded program that supports both motorized and non-motorized recreational trails across the state of Idaho. RTP funding is derived from federal gas tax revenue returned to the state for recreational trail development and maintenance.

If awarded, grant funds would support trail maintenance activities, volunteer coordination and training, and oversight of conservation corps crews. The project is intended to improve trail sustainability, increase the quality and consistency of maintenance work, and support long-term stewardship of Central Idaho’s trail systems. The project includes in-kind equipment and crew support from the One Track Mind Foundation.

Idaho Mountain Bike License Plate Fund – Ponderosa State Park Trail Project

CIMBA is also preparing an application to the Idaho Mountain Bike License Plate Fund to support trail work at Ponderosa State Park. The application will request funds to assist with trail improvements and maintenance within the park, building on recent planning and grant efforts submitted to Valley County.

The Idaho Mountain Bike License Plate Fund is administered by the Idaho Department of Parks and Recreation and is dedicated to supporting mountain bike trail development, maintenance, and stewardship across the state. If awarded, funding would help improve trail conditions, enhance user experience, and support sustainable trail management at Ponderosa State Park.

Public Comment

Public comments in support of either application are welcome and may be submitted as part of the grant packages. Community feedback helps demonstrate public interest and support for these projects.
