My wife and I decided to do the Cliffs of Moher tour while we were in Ireland. We used Extreme Ireland tours and really lucked out with Joseph Patrick Mulligan, who was absolutely fantastic, and seemed really passionate about sharing stories and knowledge about the parts of Ireland we traveled through.
My wife and I had also booked a tour to go to the Giants Causeway the next day (with a different company) we had previously booked online. I won't bad mouth the other company, but I will say our guide on that tour was nowhere near as great as Joseph.
We'll definitely be returning to Ireland, and if he's still around, would definitely do another tour with the Joseph!More
