Climbed July 2006 in a week of glorious weather in Mayo. From the col with Benbrack (see for approach) the climb is on grassy slopes, past a jumble of enormous boulders. The climb is tough and frequent stops allow the scenery to be fully appreciated, there are particulary good views back over Benbrack. To the left Benfree dominates and to the right An Cailleach and Maumonght stretch away along the Polladirk river valley. Unrelenting is another good word to use here, on the steep grass slopes. I passed a prominent outcrop of rock beyond 500 m and made the decision to head for the col with An Cailleach which i intended to climb next. This was not easy, contouring around on very steep sheep trials, the col was reached in 45 minutes. The going was now on wonderfully easy cushioned ground on the broad col. After visiting An Cailleach and Maumonght i returned to the col and climbed Muckanaght from this W side - fairly gentle on good groundand took 25 minutes. There is a small cairn at the summit, with an even smaller cairn on another little rise. I don't think there is any hill in the Bens that does not have exceptional views and this certainly fits the picture. I could see Killary Harbour and Lough Fee, backed by the big hills of Mweelrea, Sheefry and Ben Gorm. The rocky ring of hills surrounding Glencoaghan to the SW are undoubtedly the most impressive in terms of sight (and in terms of actually walking). The steep descent towards Benfree and the long long slopes of Benbaun are to the E. I took this route E, passing a small cairn, rising to yet another small cairn and then a 20 minute drop over some pretty steep and grassy ground - a nightmare in the wet i would think.
