Great Miami River Trail

Whether you are a runner, walker, or cyclist, the Great Miami River Trail (GMRT) has something for you!

The trail follows the Great Miami Riverway, which is comprised of the Great Miami, Mad and Stillwater river systems and is a recognized National Water Trail. MetroParks' southern trailhead, beginning at Timberhill MetroPark, includes access to shelters, restrooms, drinking fountains, and playgrounds. MetroParks' northern trailheads in Trenton and the City of Middletown offer multiple points of access to the GMRT. Flush restrooms, drinking fountains, and a bike repair station are located at River Center at Bicentennial Commons. Currently, MetroParks manages approximately ten miles of the GMRT in Middletown and Fairfield Township. 

The GMRT is planned to run for approximately 100 miles from the City of Sidney to Hamilton County.

Great Miami River Trail Construction Updates

Thanks to the Butler County Commissioners, MetroParks of Butler County was awarded $2.5 million in American Rescue Plan Act (ARPA) funding to help reduce trail gaps in Butler County. MetroParks also received an additional $1.1 million grant from the OKI Regional Council of Governments and a $200,000 State Capital grant to help with construction. In total, the $3.8 million awarded will help get Butler County closer to completing the trail, but additional funding will be needed to finish the current trail gaps.

Project summary

A 3.1-mile trail gap currently exists between Timberhill MetroPark and Monroe. Thanks to the Butler County Commissioners ARPA grant and the OKI grant, this project is partially funded and moving through the preliminary design phase. Construction is expected in phases between 2029-2030 and will be led by the Ohio Department of Transportation (ODOT).

A 1.6-mile trail gap also exists between Monroe and Trenton/Middletown (0.9 miles of new trail plus 0.7 miles of shared roadway along Old Oxford State Road). This project is partially funded, thanks to the ARPA award from the Butler County Commissioners and an OKI grant. MetroParks of Butler County has submitted preliminary layout plans for a new alignment along the riverside of a Miami Conservancy District flood protection levee, crossing Dicks Creek on a new bridge. ODOT will lead this project, and construction is anticipated between 2027-2028. 

A New Partnership Helps Combat Dicks Creek Erosion in Monroe

A new regional partnership between MetroParks of Butler County, the City of Monroe, the Miami Conservancy District, and the Monroe Area Community Improvement Corporation will help to reduce erosion along Dicks Creek, a barrier to completing the Great Miami River Trail through the City of Monroe. Click here to find out more.
