Slieve Gallion is an isolated outlier of the Sperrins which dominates the western shore of Lough Neagh. The earliest reference to it is in AD 670 in the Book of Armagh where it is called Collunt Patricii, 'the height of St. Patrick'. There is a traditional song called Slieve Gallion’s Braes. See Máire MacNeill, 'The Festival of Lughnasa' (pp. 150-52) for details of the festive assembly on Slieve Gallion. The names Tintagh Mountain and Glenarudda Mountain seem to refer to areas of mountain pasture on Slieve Gallion's slopes rather than separate peaks.   Slieve Gallion is the 476th highest place in Ireland.

I walked Slieve Gallion yesterday (Saturday) and what a day! The weather was perfect, the views amazing and the mountain, in general, was just beautiful! Coming from Omagh, we drove to Moneymore and about 200m outside the town there is a sign on the right hand side for Slieve Gallion 4 miles. I took this road to a cross roads and the road straight in front is the road up the mountain. There are a few houses on the road but I think the road’s main purpose is to service the telecommunications mast at the top. I had planned to start the walk from a viewpoint up this road so we drove up and parked at the picnic area and the views were spectacular when we emerged from the car! We followed the road to the first summit with the masts, meeting a lovely couple from Magherafelt on the way. We past the masts and over to the cairn and I stood in awe of the amazing views. I have heard that Slieve Gallion is good for views but this was unbelievable! The clouds threw animated shadows over the high and central Sperrins. Lough Neagh in its entirety was in view. The Antrim hills, Blue stacks – all visible! I managed to tear myself away and walked down the road again – point of note. The litter along this top part of the road after the cattle grid is a disgrace. Obviously caused by those who drive to the top and think its fine to eject their litter through the window. I had a plastic bag and collected as much that would fit and stuck it in my rucksack! It really makes me angry at the thoughtlessness of some people! We then left the road at the track Gerrym has mentioned and walked to the main summit. This is an easy enough walk on a dry day and we were very lucky. We kept an eye on the rain storms moving over the high Sperrins but they bypassed us. From the trig point we had spectacular views and since it was a good day we thought we’d take the “scenic” route back to the car. Instead of going back to the road which we should have done, since we only intended to have a short walk - we set off down along the fence - Very steep with some dangerous outcrops. Great care required in places. We walked east, traversing the slope and from the map we had two rivers to cross – unfortunately we met at least 6 fast flowing streams that were set, deeply into gully’s we spent A LOT of time looking for safe crossing points, with the result we had to keep dropping height, which was taking us further away from the car park. Anyway, after endless barbed wire fences and stream crossings we eventually hit the road and then had a 15 minute uphill walk up the car. Great walk, great day but we added an extra 2 hours onto our journey by coming back the way we did. It would have been better to park at Carndaisy forest, walk up the road and just drop down straight off the main summit without the hassle of crossing the deeply gullied streams! We live and learn and we had some laugh trying to get over the barbed wire fences without injury! Trackback:
