Glenafelly is a valley in one of the more remote parts of the Slieve Bloom Mountains and allows walkers to explore the geology and former uses of this upland area.
Situated near the entrance on private land opposite the car park is the Fiddlers Rock. This great stone of quartzite was erected in prehistoric times and demonstrates mans long occupation of this valley. The Glenafelly Eco Walk is a loop that passes through mature and semi-mature woods along river banks and on forest roads. The trail follows along both sides of a quiet and remote river valley leading into the townland of Barcam at the top of the valley. The open lower slopes of the valley along the riverbanks contrast with the seclusion of the more heavily wooded upper section.
