Glendalough State Park — a state park in Otter Tail County, Minnesota — is a rewarding subject for landscape photographers. The nearest town is Perham, about 30 km (19 mi) away (Glendalough State Park lies SSW of town).

Glendalough State Park is a state park of Minnesota, USA, in Otter Tail County near Battle Lake close to Minnesota State Highway 78. It is named after Glendalough in Ireland. The park was once used as a resort and game farm by the owners of Cowles Media Company, owner of what is today the Star Tribune newspaper. The park contains 1,931 acres (7.81 km2) on land and 1,000 acres (4.0 km2) on the water. Cowles Media Company transferred title to Glendalough to the Nature Conservancy in 1990, and the Nature Conservancy transferred title to the State of Minnesota in 1992. Glendalough was officially declared a state park with a celebration on Earth Day, April 22, 1992.From the Wikipedia article “Glendalough State Park”, licensed under CC BY-SA 4.0.
