Emerald Necklace

Cleveland Metroparks is an extensive system of nature preserves in Greater Cleveland, Ohio. Eighteen reservations, which largely encircle the city of Cleveland, follow along the shore of Lake Erie and the rivers and creeks that flow through the region. Referred to unofficially as the 'Emerald Necklace', the network of parks spans over 25,000 acres and includes over 300 miles of walking, bicycle, and horse trails as well as numerous picnic areas, nature education centers, golf courses, and countless fishing spots. In addition, the district includes the zoo in Cleveland. Four of the reservations are adjacent to Cuyahoga Valley National Park.

Although the majority of the reservations are in suburban Cuyahoga County, Brookside Reservation is located within the city of Cleveland, and the Lakefront Reservation consists of several beachfront parks spanning the city's waterfront.
