It is surrounded by the Cuilcagh Mountains and borders the counties of Leitrim and Fermanagh.A large stone known as 'Maguire's chair' is deposited on the right hand side of the road, roughly 4 miles from Glangevlin village, so-called because it was supposedly the inauguration site of the Maguire clan in medieval times.
