Carrigan Forest: Lough Formal Walk
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.

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. Retrace your steps to the junction in the path where you then turn right. The next section traces the Roogagh River and takes you deep into the forest before re-emerging onto the hill road.

Carrigan Forest: Lough Formal Walk
A very peaceful landscape to walk through, with a picturesque stop at Lough Formal. Otherwise views are restricted because of the forested landscape and be aware that the walk is almost exclusively on gravel
forestry roads. A good tramp!
Lovely area, bit of advice. Once exiting your vehicle proceed back down to were you turned in from Knockmore Road and take right were you will see a sign post for Lough Formal on the left a short way down Knockmore Road.
Don’t as I did and proceed past gate and pedestrian access we’re there are black arrows which is only part of the walk to little dog view point. Doing this will shorten the walk.
