Three Castle Head on the Mizen Peninsula is a hidden gem along the Wild Atlantic Way in West Cork. The main attraction is Dunlough Castle, with its three towers connected by a curtain wall. The trail to the castle offers stunning views of the Atlantic coastline and takes about 25 minutes to reach. It's a private sheep farm, so no dogs allowed, but a small donation helps maintain the area. Legends of the castle add an eerie touch to this picturesque spot, making it a must-visit for those seeking a unique adventure off the beaten path.
