Most of these castles are just there, free to enter, and begging to be explored. You can climb (and with the stairs rotted away sometimes you have to) and wander at your own risk, unhindered by signs or fences. Unlike the restored castles that are constantly under construction, the beauty of decay takes over and adds a life of its own to these abandoned structures.
Combine a gentle walk and a heart pounding adventure exploring tombs in the countryside. While Carrowkeel is not far from the highway, it is a bit of Ireland that not many people get to see.
Off the beaten path without being out of the way, this isolated peninsula makes the perfect picnic stop.
A road trip around Ireland and a couple days in Edinburgh. (8-15 day trip)
