Even if you don't have relatives to visit, Ireland's west country and its offshore islands offer some of the most ruggedly beautiful and culturally rich lands anywhere in the nation. But even summer highs are unlikely to get above 70 degrees, so pack for cool and rainy days no matter when you go.
Layers work well.
The pickings are slimmer on the Aran Islands. Inishmore, the largest island, is more tourist oriented, with shops offering crafts and island tours by bike or horse-drawn wagon. On Inishmaan, don't miss Teac Synge, the lovingly restored thatch-roof cottage where Irish playwright John Millington Synge spent his summers in the late 19th century. You can also rent cottages, farmhouses and even old castles. Pub fare is generally good and modestly priced.
