Kilmacrennan lies on the N56 road, 9 km northwest of Letterkenny which is the largest town in County Donegal. The village's name 'Cill Mhic nÉanáin' means 'the church of the sons of Éanán'.
Two rivers flow through the village, the Lennon and the Lurgy. Traditionally, the river Lennon was renowned for salmon fishing; however, the salmon numbers have dropped dramatically in recent years. Most anglers blame pollution for this. The salmon and trout population is slowly increasing but will take a number of years for it to reach its old level.
A 1916 Remembrance Garden was opened to the public in 2016 to mark the centenary of the Easter Rising. There are three churches: a Catholic church and the Church of St Finian and St Mark Church of Ireland in the village itself, as well as a Presbyterian Church in the townland of Leiter about 3 km away. Kilmacrennan national school is also located beside the Catholic church. It has approximately 185 pupils. It opened in 2008. The previous national school, which opened in 1935, is across the road.
