Eachmarcach is a personal name meaning 'horse-rider'. It is the origin of the surname Mac Eachmharcaigh, which can be anglicised Cafferkey or McCafferty and is a common surname in Mayo [De Bhulbh]. It would seem that this is the most likely origin of Knockaffertagh, though an Irish form for the name has not been found to support this. The t in Knockaffertagh is not a problem as the anglicisation McCafferty shows that such a pronunciation of Eachmarcach is possible. The hill is named Ummeraufferty on William Bald's map of Co. Mayo (1830), which appears to be a similar name with Ir. iomaire, 'ridge' as the first element instead of cnoc.   Knockaffertagh is the 515th highest place in Ireland. Knockaffertagh is the most easterly summit in the Nephin Begs area.

Short Summary created by Onzy  7 Oct 2014
Knockaffertagh stands on the east side of the Glendorragha Valley, north west of Cloondaff on the R317 from Newport. There are two cairns on the summit and some craggy steep ground to the south. It is more usually climbed as part of a horseshoe walk taking in an entire circuit of the valley.

There are parking spaces within the forest to the south of the valley at G042 027 starA and G035 024 starB, a good way along forest roads. From the first of these, walk east along the track, aiming to exit the forest at G048 031 starC. For the last couple of hundred metres the ground is quite soft. From here, you have 2 options, either head directly north through the scree patches and gullies of the south face, or head north east, aiming to hit the col just north of sh295 and from there onto the east shoulder and to the summit. Either way, you will need to cross the river, which should not be taken for granted.

From here you can return the same way, or, more enjoyably, continue north and complete the entire circuit of the Glendorragha Valley, taking in Birreencorragh and its two satellite peaks. Linkback:
