There is dramatic ground all around the remote Finnararagh/An Corrán; however, the top is fairly tame and there are fairly easy ways up provided you are careful. It's on a wonderful multiday ridge walk from Waterville to the Ballaghbeama Gap. Attractions incl. the 310m cliffs down to Lough Coomeen to the E and fine views over the Kenmare River. There's a narrow challenging ridge NE towards Sallagh and on towards Mullaghanattin.

From the S and E the key to ascending is to get to the col at V69782 72254 A. This can be done by :
a) start at V69259 71239 B, asking permission at the house. The track (it's the W of two shown) has a stony surface as far as Small River. Follow the river and break off eventually to the aforementioned col. From here head NNE to V70219 73121 C and then go NW to the summit. 90mins+
b) SE, start at V71137 72289 D E - ample parking, walk back 50m to farm track, up to farm sheds keeping L in farm yard pass thru gate, turning R heading to rusted gate at V70294 72080 E F - follow fence to the above col.
c) start at V71707 72935 F I - only room for one car - there is a farm track not shown on OS78 that will bring you up close to the col.

N. Park by Cloon Lough at V70825 78784 G. Walk up to Coomura then round to Coomnacronia and up to the summit. Or you could head to V70846 78403 H and head steeply up to Beann NE Top and approach F via the northern ridge...see track/2604 for access issues here.

Notable tracks incl. track/3507, track/3622 and the epic track/2604 Linkback: https://mountainviews.ie/summit/160/comment/4920/
