This 2.2-mile limestone-paved trail was built on the former Lake Erie, Alliance, and Wheeling Railroad, constructed between 1875 and 1877. Ownership changed to New York Central RR then Penn Central RR. The bridge was rebuilt in 1942 with the construction of the Berlin Reservoir damming the Mahoning River. The railroad was abandoned between 1972 and 1976.

Trail development was made possible thanks to a variety of individual and organization donations, fundraising by the Berlin Lake Association, boy scouts, volunteers, state grants, and the cooperation of Deerfield Township, ODOT, US Army Corps of Engineers, and ODNR.

The Berlin Lake Trail was initiated by the Berlin Lake Association back in 2006 when members with a vision for the future approached the Portage Park District to partner in its development. The Park District was granted a sublease on the trail from the Ohio Division of Wildlife, which leases the land from the US Army Corps of Engineers. The trail opened in the fall of 2011.

Restroom facilities on Berlin Lake can be found at the headquarters building, the picnic area by the dam, and the Circle Restaurant in Deerfield.

Berlin Lake spans three counties. The eastern portion is in Stark County, the middle portion is in Portage County, and the western portion is in Mahoning County. See the map for the county line boundaries. 

Berlin Lake lies in the northeastern part of Ohio at the junction of Stark, Portage, and Mahoning counties. The lake is located on and is accessible from US-224 and OH-14 and OH-225. The U.S. Army Corps of Engineers constructed Berlin Lake in 1942 on the Mahoning River. The Congressionally authorized purposes were flood control, low flow augmentation, water quality control, and water supply. Berlin Lake has a mean depth of 23 feet with a maximum depth of 55 feet. Annual water level fluctuations can be as much as 20 feet. Mud, sand, and gravel make up most of the bottom composition. Rock ledges can be seen along the original river channel at low pool level.

Restroom facilities can be found at the headquarters building, the picnic area by the dam, and the Circle Restaurant in Deerfield.

The Berlin Lake Trail is a 2.2 multipurpose trail crossing Berlin Lake.
