Cong is a gorgeous town just about an hour's drive away north. It's where they filmed the Quiet Man and you can have a stroll around the old abbey and walk up to Ashford Castle (which is where Pierce Brosnan got married - v posh!).

Out of town, the restaurant at the Twelve hotel in Barna (further up the coast) is absolutely amazing.
