Letterkenny

One of the fastest-growing towns in all of Ireland, Letterkenny, like Donegal to the south, is at the gateway to the far Northwest; you're likely to come through here if you're driving west out of Northern Ireland. Letterkenny's claim to fame has been that it has the longest main street in the whole country. None of Letterkenny's shops or pubs are particularly special, but lots of locals bustling around make it an interesting place to get a feel for what it's like to live in a modest-size Irish town.
