We did 2 day trip tours with Extreme Ireland. Cliffs of Mohr was with Big Mac and Blarney Castle, Rock of Cashel, and Cork was with Niall. I would definitely recommend these tours. The guides are so personal and funny. Big Mac loves to sing Irish songs while on the bus to you! They are very prompt and able to give great recommendations on places to go in the areas you're going like Cork or when you go back to Dublin. We had a great experience! — Hillary E.
