Route 1: On the N56 just S of Crolly,take a minor road on the left B833 197 A and follow along to a church car park B8387418575 B. just beyond the S end of the car parktake a track left up past a derelict building for 320m to B8402518735 C. Go up right on a less distinct track, alongside a stream, to a notch in the ridge above B8415518796 D. Head SE along a gently rising grassy hillside to a rocky knoll B8592918636 E overlooking L. Nabruckan and then past a large cairn B8561218463 F (Pt 453) on a rock strewn ridge. The mv listed co-ordinates B8570818248 G lies some 200m further along at B8570818248 G. However Pt 457 the OSI high point lies a further 100m away down a short incline and then up to a small but rounded, rock and grass covered knoll with a cairn. B8574718089 H. Until one or other set of co-ordinates is determined as the top it is easy, in a few minutes, to cross both points. Route 2: Go further SE along the minor road to B846 167 I above L. Caol. Park off road and go SE along a track around the N side of the lough and at it's end B850 163 J go NE (left) up the hillside for 1.7k to the top. For a looped walk use both routes, one up and the other down but note this requires 2k of road walking at finish. There are extensive views of the coastal scenery including the islands of Gola and Aranmore Linkback: https://new.mountainviews.ie/summit/595/comment/5354/

I climbed this hill as the first top in a round of five, all of them for the first time, on 10 August 2010. I started from the church car park suggested by eflanga at B8387418575 B. Just beyond the S end of the car park I took a track to the left up past a ruined building. After some 320 metres B8402518735 C I turned up to the right along a narrow less distinct track, alongside a stream, and followed it up to the notch in the ridge B8415518796 D. Once there I headed up SE along the gently rising hillside to a rocky knoll overlooking L Nabuckan B8592918636 E and then continued up over rocky ground to a large cairn B8561218463 F (Pt 453). From here there was still some 300 metres still to go along a broad rock strewn ridge to the top and for me, at first, a little confusion ! The current MV grid ref B8570818248 G leads to a rocky up crop about 200 metres along the ridge from the cairn and my own GPS reading cofirmed this position. However Pt 457 marked on the map as the high point (top) of the hill is over 100 metres further along down a short incline and then up to a small but very distinct rounded grass and rock covered knoll with a cairn. My photo shows the knoll and was taken from the current MV grid reference point. The reading I took for the cairn at Pt 457 was B8574718089 H. I will be interested if anyone else is of the same opinion. In the meantime an extra five minutes ensures a visit to both spots. The coastal scenery from the top is extensive from Errigal in the NW around past Bunbeg, the islands of Gola and Aranmore and then S to the Bluestacks. If the walk is only to Grogan More return by the route of ascent or go down SW to the N end of L Caol B8460016850 K and once at the road turn right and follow it back to the car park. However my next objective was Crocknafarragh over 2.5k away to the SE. ( For route followed see my comments on Crocknafarragh) Linkback: https://new.mountainviews.ie/summit/595/comment/6008/

Ascended as part of a circuit taking in Crocknafarragh. The starting point for the walk was at IB 83874 18575 B (Point A) (St Patrick’s Church). As you enter Croithlí (Crolly) take first left after filling station and before bridge/pub. Pass a quarry (left) on this narrow (waymarked) road before rounding a corner where you will see the church which is painted green. There is ample parking opposite. About 10 metres past end of the car park there is a track rising up on the left past small ruin. Take track, leaving it after about 120 metres & make for obvious gap in ridge. Here a fairly well worn path alongside stream will take you up onto height. Took bearing of 120SW up and over heather covered slope. Going relatively easy following sheep tracks. Emerged on height about 100m north of Loch Nabuckan. Decided to veer off course a little further north so as to approach An Grógan Mór summit along ridge. Cairn at IB85612 18463 and summit proper another 200m further on at IB85708 18248 Linkback: https://new.mountainviews.ie/summit/595/comment/2886/

If you want to do this in isolation, I suggest you park at B8460016850 K and proceed NE up the heathery hillside, which is steepish in parts. The views from the summit to the east are stunning and almost as good looking west over Lough Keel, in fact in all directions! Linkback: https://new.mountainviews.ie/summit/595/comment/23945/
