Climbed 5.6.04 starting at Cuilagh Mountain Park near to Marble Arch Caves (121336 I). There is a large sink hole here but very difficult to see down into due to vegetation. Cross stile and follow track. Just after crossing bridge take "floating path" off to right, this soon ends but continue in westerly direction to pick up course of Sruh Croppa River after half hour. Follow winding course of river through gully with nice waterfall and past some ruined settlements. As near summit of Tiltinbane (596m) climb away from river to the right to avoid steep gullies. Follow fenceline up to the summit - the final section is quite steep and may require use of hands. A depression next to summit cairn is perfect shelter for a brew. There are extensive views from the summit ridge - north and west towards Sligo Bay and big hills which i think were the Nephin Beg Mountains in Mayo and south over Iron Mountains. Follow path which keeps close to northern cliffs, passing fissures in rock and Lough Atona ,reaching large summit cairn after 1.5 hour walk along summit.
Had intended to return by Ulster Way between Trien and Benaughlin (marker posts just visible) but shortened journey by heading north over moor following river courses back to the track at the bridge. A long walk at 6.5 hours but rewarding with plenty of interest and some good views.

The approach from the S via Benbeg is perhaps more rewarding - it cuts out a long approach through moorland and has a fine sweeping ridge with a very different perspective on the mountain (see Benbeg for this walk). Linkback: https://mountainviews.ie/summit/165/comment/995/
