Be sure to have a full tank of gas, because Limerick is worth making a detour for. Situated 35 miles from Borrisokane, it offers up some terrific attractions, such as King John’s Castle and St. Mary’s Cathedral. Get ready to start clocking up those miles, because Galway Cathedral and Galway City Museum are also a rewarding road trip. You’ll find these fine sights in Galway, 45 miles away.
