Coomacarrea is the highpoint of the remote Glenbeigh hills which incorporate a clutch of dramatic corries in their northern grasp. The terrain is grassy/boggy with immense views over Iveragh, the Reeks and Corca Dhuibhne. Take care in mist or wind as the ground is v steep to the N.
NE. This mountain can be climbed as part of the Glenbeigh Horseshoe either from Meentog to Drung Hill or in reverse taking in seven 600m+ tops and a sub 600 if you wish. At the end of a minor road out of Glenbeigh, there is parking for either route beside a ruined cottage by the head of Coomasaharn Lake at V63625 85122 A . Head up the steep slopes of Knocknaman and continue on to Meentog before heading W on grassy, broad slopes to the col at V61996 82453 B. There are some fences and stony paths near here. Continue W up the shoulder where a fence takes a meandering line up to broad, unmarked grassy summit. If doing the full horseshoe see track/1966 - this also takes in Macklaun and is a long, tough but exhilarating 26k loop that would probably take 9 - 11 hrs.
From the same starting point, for a shorter but equally stunning loop ascend or descend via the Keamconneragh ridge - see track/3095 for a profile of this 4h+ 13k circuit.
SW A less dramatic route starts at V57456 77887 C and takes in Caunoge before heading up the SW spur of Coomacarrea. 2.5hrs+ to summit.
W. Park near V56896 83074 D and following track/3301 head up the SW ridge of Teeromoyle before turning SE for Coomacarrea. 2.5hrs+ Linkback: https://mountainviews.ie/summit/59/comment/4819/

Take a look at these lakes. Coomasaharn Lake stretches from the top of the picture, with Loughacummeen below it in the picture. This view from 500m east of Coomacarrea at V61607 82566 E seems to bring them close, however in fact they are 430m apart on the map and differ in height by 340m. A remarkable sight.

On the east side of Coomacarrea, at the col with Meenteog a road has been hacked out leading south. There are piles of buckled or worn looking mast sections and coils of rusting wire. In the picture you will also be able to see a white object, which is a large concrete block. Less visible in the picture is a nasty series of gashes in the hillside leading right to the top of Coomacarrea at the top of the fence.

It's testing for a wind power station, though it is outside the Kerry Co Co designated area for such (if that matters). As of Dec 2005 there was a mast on top of Coomacarrea. Were windmills to be put up here they would be at by far the highest site in Ireland. Coomacarrea is at 772m and the top of the windmills could be at 930m. They would be visible from much of the Dingle Peninsula, from much of the Iveragh Peninsula and even the Beara Peninsula as well as far inland in the Killarney region. The road access would inevitably bring scramblers or quads to further damage the landscape. Whether you are in favour or not about windpower (personally I am) this is not the place.
