Lough Formal Walk: Carrigan Forest is part of the Marble Arch Caves Global Geopark. The Lough Formal walk is almost all on forestry tracks and features a short path through the heather to the summit of Formal More. This brisk walk is a chance to fill your lungs with mountain forest air while enjoying the views from Formal More, looking at some features of geological interest and experiencing a touch of wilderness. Sitting quietly for a while, you may be surprised at how much wildlife comes to you, in this seemingly barren woodland.

    Route Description

    From the car park, follow the black route as indicated by the way marked posts. This takes you west along a short section of minor road, where the route then branches left onto a forest track. The route takes you through corridors of forest, opening up as you near Lough Formal. Take a moment to watch for woodland wildlife on one of the benches overlooking Lough Formal and proceed along the shores of the lough before making the short climb up Formal More to enjoy the views towards Lough Melvin, Donegal Bay and Cuilcagh Mountain.
