Glenfarne Demesne was once part of the Tottenham Estate which had land in Leitrim which amounted to over 14,500 acres in the 1870s.
The estate is about 1.5 km north of Glenfarne on Manorhamilton/Enniskillen road. There is a picnic area and boat quay at the lake, but the road through the Demesne is not open to the public. There is ample parking. Looped trails, of varyong lengths, take you from the car park along the edge of Lough MacNean, returning through a diverse and varied commercial forest. The trails offers panoramic views of Northern Ireland on the other side of the lake. Adjacent to the trails is the feature known as Myles Big Stone. From here, there is a panoramic view of Lough MacNean and the surrounding countryside. This Stone is thought to have been a place of worship in olden times. Mainly coniferous plantations can be seen along this trail with some beech, birch, holly and alder.
