Along the Beech Trail, you'll discover some of the oldest trees on the estate, including Oak and the sprawling limbs of this Horse Chestnut, forming a natural arch over the path.

"continual slur on Irish caving" It's actually only a few hundred metres is accessible and it's total length is thought to be 2km. No where near the longest cave in Ireland. Consider a trip in only if well equipped with a good light and helmet. Alternatively/also consider visiting McKenzies back lounge just down the road. A much drier watering hole. ;)

In the graveyard are several interesting stones, probably the most noted one is known as the Bishops stone, this odd shaped stone has been altered and reused several times, originally thought to have been a carved figure similar to those on nearby White Island. Another stone with a lot of history is the large slab standing west of the bishops stone, one side of the stone bears at least twelve cup-shaped hollows, see image above right, which suggest this maybe a multiple bullaun stone/cup marked stone that has been reused as an early Christian cross slab, as on the obverse face is a Greek cross in a circle with a bifurcated stem. Situated south of the bullaun stone is a holed stone, as the image shows this stone is half embedded in the ground. Immediately to the West of the holed stone is a broken 1.2 metre high stone pillar. This stone may have been damaged. http://www.megalithicireland.com/Killadeas.htm

Pollnagollum Cave (meaning Hole of the Dove) is the longest cave system in Ireland. The cave system is complex and fascinating and is fed by a tumbling waterfall that topples off a limestone cliff. Watch your stepping here as rocks can be unstable and slippery, and don't forget your camera for some awesome shots.
