Visit Notes

Tuesday, 19th March 2002

I have driven past here many times, but have never bothered to stop off. Afterall there is nothing megalithic about these woods. Anyway I decided to see what it looked like as part of my "getting to know the landscape around Dublin better" project.

My first surprise and tantalization was a huge granite plateau exposed on the top of the hill. From this space (without the hideous surrounding pine plantation) the views of Howth and the bay would have been stunning and very similar to Carrickgollogan.

Just in case I spent a good half hour scouring the exposed rock for signs of scribblings or rock art but to no avail. Perhaps these rocks were not exposed way back.

Directions

Heading south from Stepaside through Kiltiernan take the first left after passing the R116 junction. Follow this road around and just after the second left you will see a car park on the right. There is a good map in the car park that shows you where the granite plateau is.

About Coordinates Displayed

This is an explanation of (and a bit of a disclaimer for) the coordinates I provide.

Where a GPS figure is given this is the master for all other coordinates. According to my Garmin these are quite accurate.

Where there is no GPS figure the 6 figure grid reference is master for the others. This may not be very accurate as it could have come from the OS maps and could have been read by eye. Consequently, all other cordinates are going to have inaccuracies.

The calculation of Longitude and Latitude uses an algorithm that is not 100% accurate. The long/lat figures are used as a basis for calculating the UTM & ITM coordinates. Consequently, UTM & ITM coordinates are slightly out.

UTM is a global coordinate system - Universal Transverse Mercator - that is at the core of the GPS system.

ITM is the new coordinate system - Irish Transverse Mercator - that is more accurate and more GPS friendly than the Irish Grid Reference system. This will be used on the next generation of Irish OS maps.
