This forest includes a hilltop passage tomb, located deep in the forest north of Augher. It is topped by extraordinary decorated stones said to mark the grave of Queen Aine, who ruled during the second century.
The stones are inscribed with megalithic designs that are considered among the finest from this period located in all of Ulster. To reach the tomb, visitors must climb a steep path 1-¼ miles long, that winds its way from the upper parking area.
Below the hilltop monument, in another part of Knockmany Forest lies Ardushin Lough, which can be enjoyed to the fullest by following the 1-½ mile long lakeside path that proceeds through a striking group of mature Douglas Fir trees that are more than 80 years old.
