(1) Bunannio Bridge Route: Start around L737 943 A. Take the well made track E up to a T junction L751 948 B, turn left and follow track to its end L749 950 C. Go NW up the hillside for some 1.2k over short heather to the summit trig pillar. Return by way of ascent.

(2) Belfarsad Bridge Route: From L748 985 D just N of the bridge take the track SE to L766 977 E. Leave track and continue SE to the start of a prominent spur L768973 F. Follow the spur steeply up SW for about 1k to L757 966 G where the slope eases and then go SSW. Once on the flatter ground of the Plateau go SW across to the summit trig pillar. Return by route of ascent. This route offers an opportunity to view the precipitous north facing cliffs of the hill and its deep sided corries and loughs not seen on the more direct but easier route 1.

If climbing Corraun Hill it is well worth considering taking a looped walk which also includes the slightly higher Slieve Aghkerane or Corraun Hill E Top. To do so descend SE to a broad saddle at L761 957 H (Pt 421) and pick up the route from this point as described in the short summary for Slieve Aghkerane..
