Day tours from Galway

Any recommendations for small day tours from Galway. I want to see it all and have so little time. I think we can visit the Cliffs on our way from Dingle to Galway, but like to have a tour for some of the other sites. Also anyone taken a tour that allows for a view of the Cliffs from the Atlantic and a visit to to the Aran Islands. We are going in mid September and praying for good weather
