Seahan has two megalithic cairns on its summit. Liam Price noted that Seahan appears on the Down Survey maps as Seavick na bantree and rightly interpreted this as Ir. Suidhe Mhic na Baintrighe, 'seat of the widow's son'. However, he believed that the story behind the name would never be understood: This curious name must have some reference to old traditions about the ancient burial cairns which crown the top of this mountain. All such traditions about this place have long ago disappeared (The Antiquities and Place Names of South County Dublin, Dublin Historical Record, vol. ii, no. 4, 121-33). While the precise story may never be recovered, it should be noted that Mac na Baintrí, the widow's son, is a common figure in Irish folktales whose characteristics are eternal persistence and ingenuity in the face of adversity.   Seahan is the third highest mountain in the Dublin area and the 205th highest in Ireland. Seahan is the third highest point in county Dublin.

Normal walk up Dublin Neighbour turns into Ethereal Christmas Cairnscape!
by Ronan119  2 Jan 2021
Walked up to Seahan in December from the forest path coming up from Ballinascorney.
Walked through the forest and saw a herd of Shetland ponies coupled with a larger Horse of unknown breed. After getting over the fence, (I do not recommend this route!) I got to the main track which runs parallel with the Dodder/Bohernabreena reservoir
below, rapidly passing out routing fairweather walkers who had evidently not bargained for the encroaching mist, or gods help them, actual height of the mountains.

At this stage, there was almost no sound, and the corpses of cut down trees which garnish the ground cast ghoulish shadows worthy of any great war reenactment.
As the mist grew fatter, I heard a strange noise piercing the mountainside, and my imagination summoned Demons of ancient myth from Fomorians to Fir Bolg. I also knew I was now a star of a 'think we're alone now' cover. However I realized what the unwelcome sight was: a solo Quad-biker who felt utterly entitled to churn up the trackway (which is already in a sorry state), though he was actually polite - I resisted the urge to pull a Braveheart on him for his environmental sacrilege, nonetheless I feel this should not be encouraged. Not long after, I noticed ice sheeting the rivulets of water which trickled off the hillside, and finally I reached the snowline, where layered feathers of the North Pole's best transformed the scene into a soundless moonscape. Stalagmitic daggers hung off the nearby bogland, and I noticed a sculpture of ice somebody had erected atop some bracken nearby - to which I added an axelike shard of rock from nearby. I pressed on and, only 100 metres away, the Cairn emerged from the mist like the prow of a ship near some far-flung glacier.

I stood on the Cairn (which has centuries on the Pyramids and was already ancient when the Romans first conquered our Welsh neighbours). The so-called 'Ava's monument' on top had been blasted by ice and yet there was almost no wind. Indeed the scene was a churchlike silence to which I can do justice only by encouraging repeat walks by others when similar conditions allow and align. Tried being smart and covering a new route on the way back as the darkness rose-all I will say is, don't do that. Anyway. Some say the ancients believed these monuments were a gateway to another world. After my experience, I can't say as they were wrong. Linkback: https://mountainviews.ie/summit/200/comment/21950/

May the (gale) force be with ye!
by mcrtchly  9 Nov 2010
Twenty five years ago I climbed Seahan on a cold winter’s day when the ground was covered in snow and the wind gave an almost arctic feel. The route taken that day was as described in the “Irish Walk Guides – East”. We decided to follow the route again last Sunday (the day of first incoming major storm of the winter). The route starts at the junction of the R114 with the road to Glenasmole at O08193 23076 A where there is a small pull-in suitable for a few cars. The original route passed through a gate on the south side of the junction and steeply up a field. Here we found our first obstacle which was a bracken and bramble covered slope. We declined a tussle with the vegetation and head off towards the SE along the Glenasmole road for about 300m until a forest road is met. This forest road was taken through mature woodland in a SE direction for about 700m to a switch back at O08545 22469 B. Soon after this the forest road peters out and a boundary is encountered with newer forestry to the west. This forestry wasn’t here on my last visit 25 years ago. A small cairn at O08332 22687 C makes an indistinct break in the forestry which leads uphill in a SW direction. Soon the break disappeared and we were forced to fight through the under storey of trees to eventually reach the top of Slievenabawnoge hill (O08068 22569 D). Another break in the trees headed off in a SSE direction to met an area of recent clear felled trees. This presented a new challenge of crossing piles of fallen branches and tree roots left after the felling until another stand of mature forestry was met. Now there was clear path along the side of the forestry heading uphill towards Seahan. Off-road motorbikes had been here before and churned up the path into a muddy wallow all the way to the top.

Our fight to the summit of Seahan by the chosen route was accompanied by increasing winds as the day wore on and the deep frontal depression approached Ireland. The summit of Seahan has a number of burial tombs which we believed to date from Neolithic times. Our assumption of their age was challenged by an ominous presence on the summit trig point – Darth Vader himself!. Resplendent with a glowing red ‘light’ sabre pointing to the north. Is Seahan some form of portal to Tatooine (Darth Vader’s home planet)?. Or perhaps he is warding off hillwalking invaders from the North?. We wait to see what happens in the next sequel/prequel of Star Wars – perhaps the Wicklow Mountains will be the battle ground between the Rebel Alliance (Mountainviewers) and the Empire (Mountaineering I…..).

Following our encounter with Darth Vader (and a quick traverse to Corrig and back) we beat a hasty retreat down back to the car pursued by now near gale force winds (MAY THE FORCE BE WITH YOU).

PS. I don’t recommend the route we took. A much easier route is now possible from the R114 by taking a forest track along the edge of the Kilbride rifle range at O073200 E as described by Wicklore. Linkback: https://mountainviews.ie/summit/200/comment/6159/

From the pillar on Corrig to Seahan is 0.99km for those interested in stats! We took a coffee break and thought about how we were going to get down to the road. I think three cairns in one day must be my record, but it was a wonderful walk. One correction to Sheet 56 I would advise is that the cairn is placed in woodland on the map but this woodland is many hundreds of metres away both in a northern and western direction. So be warned! We took heed of advise read on this site and kept well to the right of the Kilbride Rifle Range, coming to a fence surrounding young trees. Directly ahead we could see a forest road coming in off the public road so we went through the trees, picking our steps carefully, and made our way to the road. A half hour or so and we had got back to our car, without incident. A lovely walk, and it took about 5 and a half hours altogether, over the almost 17km covered.

Question for regular climbers of Seehan. I am doing research on Peat landslides and the causes of them. There is one south-west of seehan, which is clearly visible from its summit (see picture). I am wondering if any hillwalkers would know anything about when it happened?

Harry Goodman on Seahan, 2010
by Harry Goodman  5 Apr 2010
As I was in Dubin over the week-end I decided on Sat 6 Mar 2010 to tackle two of the 600m mountains in Dublin/Wicklow that I had not yet climbed, Seahan and Corrig Mountain. I followed the R114 towards Brittas and at the top of the incline at approx O 0750022800 F turned left onto the L7462. As I did not have this reference before setting out I had some difficulty in locating this side road. I therefore give above directions for those who, like myself, are not regular walkers in the area. The start point for my walk was a forestry track some 3k along this side road, on the left at O 073520100 with parking for several cars. The track was covered in snow and ice and undulated along to a T junction O 0825021050 G at a less well defined path where I turned right, steeply uphill, for a short walk to a fence and open hillside. From here I turned right along the track following the forest edge and made for Ballymorefin Hill, a "bump" on the way to Seahan. I was suprised to find the track was fence deep in snow and sought to make easier progress by moving across to more open ground on the hillside with less snow cover. There were constant views SE to Corrig as I climbed. At a point where the fence and forest edge swung to the right I continued SE to the cairned top of Seahan. The views south were dominated by Kippure and Seefingan, while Dublin and the lower hills above it were to the NE. From here it had been my plan to walk out and back to Corrig Mountain and then descend to the road by the forest edge and back to the start. However given the fine conditions on the day I decided, when I reached Corrig Mountain, to continue on and complete the full Circuit of Kilbride with walks over Seefingan and Seefin, two tops that I had previously climbed.

Climbed 10/02/07 as part of Seefingan Circuit, submitted by Djouce (see Walks Section). Having visited Seefin, Seefingan & Corrig Mtn I now set a bearing of 296 degrees from Corrig’s summit IO 09050 19373 H , necessary given the mist enveloped summits on the day in question. It was in this stage of the walk that I encountered the deepest snow thus far on the walk. I was regularly wading through snow which reached my knees. Obviously a good deal of this had drifted onto the slopes of Corrig & Seahan and especially in the col between. It was on the col where I believe I encountered my first ‘white-out’. Now, I have never experienced this phenomenon before but given what I have read about them I think this definitely qualified. Having trudged through the ever deepening snow from Corrig’s summit I suddenly found myself faced by, what I can only describe as a wall of pure white. I couldn’t distinguish ground from sky, nor up from down and an eerie silence had descended around me. There was just a somewhat disturbing, yet peaceful, feeling of nothingness. Thankfully, compass & map to hand I wasn’t too worried and started off again, maintaining my bearing. Eventually, the snow appeared to thin out underfoot and there emerging from the mist in front of me was the summit cairn. From here I took my last bearing of the day (289 degrees), one which would take me onto the road running paralell to the rifle range. The snow became deep again for a time as I descended until I reached the perimeter fence. From here, having climbed over the fence, I made my way with due care down through a fairly recently replanted area of forestry. Eventually, I emerged from the mist that had covered all four hills on the walk. Below me in the distance I could see a couple of houses and off to the left another perimeter fence. I found that my bearing took me towards the fence and I noticed a set of footprints heading up in the direction from which I had just come. I followed these and found that they crossed the fence onto a snow-covered track within the military range. I decide the going would be easier on that side. From here it was a straightforward walk down to the road and then a 2K walk back to where I had parked the car, IO 06286 16865 I, some 3.5 hours earlier that morning. All together, this was a most enjoyable walk despite the absence of any views from the various summits and I will definitely revisit the circuit, hopefully on a clear day.
