Followed the minor roads out of Carracastle (G545002 A, M542994 B & M537995 C, being the appropriate road junctions) and parked at a track junction at M533985 D. A 4 wheel drive vehicle is more suitable for this last track, as it is of the gravel forestry type.

Walked along the tracks to the communication masts, a new track, unmarked on the map, branches off just where you make a sharp right turn for the final ascent to the masts. At the masts, I crossed a barbed wire fence (on the right) and made my way round to the far side of the masts, which is as interesting as paddyhillsbagger says. Given the size of the summit contour, I went for a wander in a north east direction. Well, it was a bit of an assault course really, over fallen trees and moss covered ditches, but I did get a gps height reading one metre higher than I did at the masts!

There was an old planning notice tied to the masts railings, so it appears that there is further "development" to come on this MV summit. Oh, and the position of the road & mast on the map (& satmap) is a little off, according to my gps readings. Linkback: https://mountainviews.ie/summit/1016/comment/5944/

Drove up the gravel road and parked. From here it's about a kilometre stroll up to the mast area. It's very overgrown around the compound now but it's possible to squeeze in along one side of the fence and jiggle around a bit to what might be the actual summit.
No views up at the mast but it's a pleasant stroll to kill a half hour or so on the road to the West. Strictly to be ticked off - not worth doing this one more than once. Linkback: https://mountainviews.ie/summit/1016/comment/24063/
