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/
