I did the castle tour yesterday and our driver Eoin was a fantastic guide. Lots of information and even more great jokes. Trips like that can easily get boring if it's too serious but Eoin did a great mixture of fun and information. Highly recommend this guy. The castle itself is stunning especially the "magic painting". The bus for the tour was very nice as well. After the castle the bus stopped in a small fisherman village for a short rest. Also a nice spot for a coffee or a snack.
