Maumtrasna

Maumtrasna, historically Formnamore (Formna Mór, 'the great shoulder'), is the highest of the Partry Mountains in south County Mayo, Ireland, rising to 682 m above sea level. The summit is broad and flat with several ridges running off it, including Skeltia (An Scoltach), Benwee (Binn Bhuí), Buckaun (An Bocán) and Binnaw (Binn Fheá). The peak of Knocklaur (Cnoc Láir, 'middle hill') stands on the ridge between Maumtrasna and Devilsmother mountains.

The name 'Maumtrasna' comes from Mám Trasna, meaning "the pass across", and originally meant the hill pass on the road between Lough Nafooey and Lough Mask. The townland of Maumtrasna is on the south bank of the Srahnalong river. The townland was the location of the infamous Maumtrasna murders in 1882.
