This is normally done in conjunction with Coomcathcun, but may also be completed in isolation. Take the road to the NW of Sneem (following the Sneem River), turning left at point V672 698 A and following the narrow road around to the left until it terminates beside a farmhouse. Ask permission here for access and parking (as of Feb 2016 the elderly farmer has no objection to walkers, but won't allow dogs).

Continue on foot past the farmhouse, swinging to the right almost immediately before old stone building. (See pic inset). Follow this track for about 100m until you come to a gate. Do not continue through gate. Instead, on the left is a muddy sheep pen and behind it, very easy to miss, is a track that curves to the north of Dromtine Lough (in red on pic).

Follow this track, crossing the shallow stream and you will then emerge on open mountainside. Proceed directly west over grassy, steepish terrain. You will need to veer to south or north slightly to pass some steep rock outcrops, after which the incline eases. Continue over several humps for about 1.5km then turn south at point V644 705 B. Continue for 500m over mostly rocky/grassy surface to reach the summit, which is marked by a pile of stones. From car to summit to car took 4 hours, although conditions were very poor.

See comments under Coomnahorna for details of horseshoe route (Coomahorna, Slieveshaska South & Slieveshaska). Lovely rock-bound lakes to the west of the summit. Massive strata twisted and buckled. Slow going over rough ground. Amazing country. Linkback: https://mountainviews.ie/summit/1424/comment/19944/

This is a very rare new addition to the Arderin list and would normally be done in conjunction with Coomcathcun or Coomnahorna and Coomcallee from the south, but if you've already bagged those and missed this one, then it's possible to do it on its own, and with relative ease, from the east. Unfortunately, the day we did it, the rain, wind and cold were unrelentingly cruel! This slowed our ascent considerably (multiple slippages), although overall, the terrain is pretty solid and not too steep. See short summary for access, directions etc. The mountain's aspect from the ridge to the NE is very impressive - a gigantic wall of precipitous rock, with Slievenashaska Lough nestling to the mountain's equally steep south face. The final 500m as you turn south offers multiple, pretty loughs amid a terrain of rock and grass. The summit is marked by a largish pile of rocks and overlooks the lough to the south. Overall, a very worthy Arderin. Linkback: https://mountainviews.ie/summit/1424/comment/18446/

In order to get a general idea of approaching Slievenashaska S from the south, here is a simulated aerial picture. Linkback: https://mountainviews.ie/summit/1424/comment/23293/
