Rahinnane Castle was one of my favorite places we visited while driving the Dingle Peninsula. We followed our GPS to get to the general area (the roads are unnamed but Google Maps recognizes the name) and then saw it in the distance across a field. We followed some homemade signs that directed you to park next to a barn. As we tried to figure out what to do next, a lady came out and told us it was 2 EUR each to see the castle. We paid and then she told us to walk through her yard, through the fence, and across the field. The field was extremely muddy and is home to livestock so watch your step (unfortunately I discovered that part the hard way...not my proudest moment). I don't think the castle actually resides on this family's land but they seem to have a monopoly on the access. Even after walking over, we didn't see a better way to have arrived. If you are using a GPS to navigate, the GPS coordinates are 52.143510, -10.382297.
The castle itself is breathtaking and it looked pretty sturdy for being in ruins. We were the only ones there at that time. It was so peaceful as we were free to explore the castle without anyone else to disturb us. There is an information board sitting outside that gives you a brief history. I really didn't want to leave but we wanted to explore more of the peninsula before sunset so we only spent about 15 minutes looking around.
This was probably the sketchiest place we visited but it was worth it. The 2 EUR admission was pretty standard for other more established looking destinations. 5 stars. read more
