Visit Notes

Sunday, 6th December 2009

This mighty cairn is actually just inside a military firing range, so I can't really recommend that people visit this one. It is only just inside the designated area and lots of people to visit this mountain top, so it's up to you.

The site overlooks nearby the passage tombs at Seahan Hill (County Dublin) and Seefin Hill (County Wicklow). It is in turn overlooked by the cairn-less Kippure Mountain. It is very likely that the cairn on Seefingan contains a passage tomb, too.

The cairn stands in a hollow in the surrounding peat. It is about 4m-5m high, but looks shorter on approach due to the hollow. It is is over 30m in diameter and has an OS trig point on its top. A couple of dips in the northside of the cairn could be where the entrance to the passage is located.

The views from this mountain top site are wonderful. You can see the aforementioned passage tombs, the flatlands of Kildare and even over Dublin City. Howth and Lambay are clearly visible.

I didn't realise that my camera was set to some very odd settings until I started to descend, so my images need a bit of work to make them right. Note to self: Always reset your camera when you put it away!

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.
