There is parking for several cars at the entrance to Cronalaght Windfarm. The entrance to the windfarm is gated, but there is a pedestrian gate allowing access for walkers. Proceed up the tarred access road for 2km, taking you to the unlisted Cronalagh hill. Veer NE then for another 2km, at first losing some height and then slowly gaining it again, crossing multiple large peat hag areas along the way. At point B87695 25489 A turn directly east another 1km up the gently rising slope, taking you to the high point, which is marked by a large cairn.

Descending from Carntreena or Tievealehid towards Gweedore, you are rewarded on a fine day with perhaps one of the finest views of iconic Errigal to be had - especially if the summer wildflowers are in bloom. Linkback: https://mountainviews.ie/summit/716/comment/23610/

I climbed Carntreena (Carn Traonach) on 30 July as part of a circuit of Tievealehid (Taobh an Leithid). It has a bald, stoney, rounded top, with an expansive summit cairn and a fantastic panorama of the Donegal Highlands to the East. About 200 metres to the NNW of the large summit cairn is a small cairned rockey outcrop which is also worth a visit. To anyone wanting to climb this hill I would commend a round which includes the other nearby tops of Malaidh na Leacht and Tievealehid (Taobh an Leithid) starting at the access road to the Wind Farm on Malaidh na Leacht Map Ref. B855227 B. A shorter and more direct approach can of course be made from some point along the N56 which runs S to N to the E of the hill. Linkback: https://mountainviews.ie/summit/716/comment/3998/
