Known as Correl Glen and a designated Nature Reserve, the short trail follows a wooded ravine cut by the Sillees River, as it bubbles and foams between birch, oak, and holly. The woodland extends in three fingers across this Environment and Heritage Service reserve. The heath in between is formed of mosses, purple heathers and the aromatic bog myrtle. Lichens grow well amongst the heath, 131 varieties having been recorded so far, and indicate the air here is clean. Correl Glen is host to many species of butterfly and dragonfly. The S ilver-washed Fritillary, the largest butterfly in Ireland, may be seen in clearings throughout May. The path starts at Falls Bridge car park, passes through the damp, shady wood where the branches are draped with mosses and lichens. As the path ascends there are views of Carrick Lough and from the top of the heath covered hill, you have striking panoramic views of limestone hills to the south. Wooden seats are at various stages of the route and at the viewpoint, from where the path descends to the starting point.
