Letterkenny in the context of "Blue Stack Mountains"

The Derryveagh Mountains (Irish: Cnoic Dhoire Bheatha) are the major mountain range in County Donegal, Ireland. It makes up much of the landmass of the county and is the area of Ireland with the lowest population density. The mountains separate the coastal parts of the county, such as Gweedore and Glenties, from the major inland towns such as Ballybofey and Letterkenny. Its highest peak is Errigal.

The River Swilly (Irish: An tSúileach) is a river in County Donegal, Ireland, which flows in an eastern direction through Letterkenny. Letterkenny, the largest town in County Donegal, is built on the river and became the first crossing point on the river in the 17th century.

Kilmacrennan (Irish: Cill Mhic nÉanáin or Cill Mhic Réanáin), also Kilmacrenan, is a village, townland and civil parish in County Donegal, Ireland. The village population was 888, as of the 2022 census. The village's population has increased steadily over the last decade with many new housing developments catering, in particular, for an overspill population from Letterkenny. Kilmacrennan was historically the caput of its eponymous Barony of Kilmacrennan, of the eight Baronies of Donegal.

The Battle of Kilmacrennan was fought near the village in 1608 during O'Doherty's Rebellion.

Lifford (Irish: Leifear, historically anglicised as Liffer) is the county town of County Donegal, Ireland, the administrative centre of the county and the seat of Donegal County Council, although the town of Letterkenny is often mistaken as holding this role.

Lifford lies in the Finn Valley area of East Donegal where the River Finn meets the River Mourne to create the River Foyle. The Burn Dale (also spelt as the Burn Deele), which flows through Ballindrait, flows into the River Foyle on the northern outskirts of Lifford.

The N2 road is a national primary road in Ireland, running from Dublin to the border with Northern Ireland at Moy Bridge near Aughnacloy, County Tyrone to connect Dublin with Derry and Letterkenny via the A5. A section of the route near Dublin forms the M2 motorway.

Monaghan (/ˈmɒnəhən/ MON-ə-hən; Irish: Muineachán [ˈmˠɪnʲəxaːnˠ]) is the county town of County Monaghan, Ireland. It also provides the name of its civil parish and Monaghan barony.

The population of the town as of the 2022 census was 7,894. The town is on the N2 road from Dublin to Derry and Letterkenny.

Strabane (/strəˈbæn/; from Irish An Srath Bán, meaning 'the white river-holm') is a town in County Tyrone, Northern Ireland.

Strabane had a population of 13,507 at the 2021 census. It lies on the east bank of the River Foyle. It is roughly midway from Omagh, Derry and Letterkenny. The River Foyle marks the border between Northern Ireland and the Republic of Ireland. On the other side of the river (across Lifford Bridge) is the smaller town of Lifford, which is the county town of Donegal. The River Mourne flows through the centre of the town and meets the Finn to form the Foyle River. A large hill named Knockavoe, which marks the beginning of the Sperrin Mountains, forms the backdrop to the town.
