Tips from the Community
The well-signposted paths lead you through dense forests and offer impressive views of Carlingford Lough and the Mourne Mountains. The mountain bike routes in particular are varied and require both fitness and technique. However, some sections can be slippery in wet weather, so caution is advised. A highlight is the Cloughmore Stone, a huge boulder that was transported here during the last ice age. The approach there is steep, but the view makes up for the effort.

Beautiful Forest features scenic trails with amazing views of Carlingford Lough, especially from The Cloghmore Stone, a 40 tonne granite boulder which was deposited here at the end of the last ice age. The Oak wood is a Special Area of Conservation believed to be over 250 years old. It is a remnant of the old oak woodlands that clothed the lower slopes of the Mournes several centuries ago. Most of these oak woods were cleared during the 18th and 19th centuries for use in boat building.

Nice and peaceful place with a bench that's perfect for resting weary legs and watching the wildlife around the lake. Even with the new gravel path this area can get quite boggy so best to wear the boots.
