There are two waymarked trails in Slievethoul and Lugg Woods, providing a pleasant walk with some lovely views to the south and east of the Dublin/Wicklow Mountains and northwest over the plains of Kildare.
Slievethoul was formed from glacial deposits of sandstone, siltstone and shale laid down at the end of the last Ice Age. Much of the hill has been replanted with spruce and larch.
There are fine views from the summit and a wealth of archaeological sites with 5 monuments in and around Slievethoul Wood. On the summit, there are 2 monuments, one is a megalithic tomb dating between 3500-3000BC. This monument consists of cairn, a chamber, a distinctive outer ring of monoliths and possible kerbstone on its northern side. The other monument is a barrow or ring-barrow from the Bronze/Iron Age tradition (c.2400BC to 400AD). It consists of a circular or oval raised area defined by a low internal bank surrounded by a ditch.
The Saggart Hill loop extends 3.8km and is graded easy and waymarked with green. The second longer loop, 8.7km in length, includes the loop of Slievethoul and nearby Lugg Wood. It is graded moderate and waymarked with orange discs. Please take care walking the small section of public road between the two forests.
