Garraun South Top is situated in the less-visited northern half of the Twelve Bens, separated from the more prominent hills by the N59. It lends itself well to being combined in routes with other hills, particularly Benchoona and Garraun itself, but also Doughruagh further southwest. The summit itself is an unremarkable grassy mound marked only by a handful of stones. 800m out the western spur however, lies the more satisfyingly craggy Altnagaighera (not an MV listed hill) with a great impression of exposure.

The most direct way to this summit alone would be to ascend by the obvious spur to its south and east. Park on the road at the southern end of Lough Fee (L804 596 A) and head north along a farm track skirting the western side of the lake. At around L800 600 B, head west over featureless and wet ground onto the spur. This could be combined with visits to Benchoona and Garraun, before descending by the eastern spur off Garraun and back to Lough Fee.

A more challenging route begins from the northern end of Lough Fee (L780 621 C), and ascends the eastern spur of Benchoona before heading south to Garruan South Top itself. This route is best left for a dry day with good visibility. It is also better for ascent than descent.

Garraun South Top can also be reached from Lettergesh to the northwest, beginning at L74958 63413 D and ascending over Benchoona to the summit. Linkback: https://mountainviews.ie/summit/347/comment/5107/
