Storm the castle at Rock of Dunamase, a fortress dating back to the 12th century and once pillaged by Vikings. The rock itself stands above a flat plain, which holds the castle ruins and offers picturesque views of the countryside. The structure has passed through many hands, including the Normans and local Irish lords, and local tradition says it was besieged and blown up by the Cromwellian generals in 1651. While there are no records of these events, it is probably the best explanation for the ruins you can explore today. Take care when navigating the castle, as some parts can be dangerous.

  • Allow you to explore the remains of the castle. As it's the highest point around the area, you might be able to take some nice photos. Can park in front of the small church, of which you may need to locate it on Google Map manually.
  • Awesome place with great views. Good for a short hiking. Not crowded. Roads are very narrow. Road signs are hardly visible due to vegetation. If you are new to the area, I recommend great caution ⚠️.
