Kilkenny to Sligo: A Wild Atlantic Road Trip Guide

Did you know that the M7/M18 route from Kilkenny to Sligo passes within 1 km of the Hill of Uisneach, the ancient sacred centre of Ireland? This 220 km drive typically takes 2 hours 40 minutes non-stop via the M7, M18, and N17, but the best stops along the way add unexpected depth. For tips on how to find the best stops and hidden gems between cities, this guide covers it all.

This route is primarily motorway (M7 and M18) with a 70 km stretch of national road (N17) from Tuam to Sligo. There are no tolls on the M7 between Kilkenny and Limerick; the M18 is toll-free. Fuel stations are abundant every 20-30 km, but on the N17 section, stations are sparser – plan to fill up in Tuam. Estimated fuel cost for a typical petrol car at €1.60/litre is around €35-40, given 7.5 L/100 km consumption. For diesel, expect €30-35. Driving at 100 km/h on the N17 improves efficiency by 10-15%.

• Fuel stations: Frequent on M7/M18; last major station before Sligo is in Charlestown (N17).
• Road conditions: M7/M18 excellent; N17 single carriageway with occasional bumps.
• Toll: None on this specific route.
• Parking: Ample free parking at most attractions.

The M7/M18 is well-lit at junctions, but the N17 has no lighting between towns. Night driving requires high beams and caution for wildlife (deer, badgers) near Lough Arrow. Speed cameras are frequent on the M7 near Nenagh. For families, the Lough Derg Water Sports (near Portumna, M18 exit) offers kayaking and pedalos. The Honey Pot in Ballinasloe has a soft play area. Dogs are welcome at Glencar Waterfall (N17 detour) on a leash. For rest, the junction 27 services on M7 (Birdhill) have 24-hour parking and a coffee shop. The Davitt Quarter in Charlestown has a safe parking area for naps. Top things to do between Kilkenny and Sligo include exploring the Hill of Uisneach (5-min detour near Mullingar) and visiting the Teeling Whiskey Distillery (M18 exit 12, Roxborough).

• Pet-friendly: Many N17 service stations allow dogs; Rua Café in Sligo town is pet-friendly.
• Fatigue spots: Junction 27 M7, Ballinasloe town park (quiet benches).
• Hidden gems: The abandoned Killone Abbey ruins (3-min detour from N17 near Claremorris); Lough Bo viewpoint (5-min detour near Ballyhaunis).
• Child-friendly: Attymon Native Pine Forest (M18 exit) offers easy walks; Loughrea Cathedral has a historical treasure hunt.

Leaving Kilkenny's limestone plain, the route crosses the River Suir near Carrick-on-Suir. The M7 then skirts the Silvermines Mountains (southeast) and the Slieve Bloom range to the east. As you enter County Tipperary, the landscape opens to rolling green hills dotted with limestone outcrops. Near Birdhill, the M18 begins, slicing through the flat Burren-like terrain of northern Clare. This area is famed for its karst landscape – though not a UNESCO site, the Burren is a candidate. The N17 from Tuam to Sligo passes through drumlin country, with hundreds of small hills shaped by glaciers.

• UNESCO sites: None directly on route; however, the Brú na Bóinne complex (Newgrange) is a 1.5-hour detour east. Sligo’s Carrowmore and Creevykeel are on the tentative list.
• Natural landmarks: Lough Derg (view from M18 near Birdhill), Lough Arrow (N17 detour), Benbulben (visible near Sligo).
• Local crafts: In Claremorris (N17), stop at the Sliabh Aughty Arts & Crafts shop for handmade pottery.
