We had been in the very touristy visitors center at Mizen Head on Friday and decided that we didn't want to spend the €7.50 each for the tourist experience out across the bridge. We knew there had to be a nice coastal walk in the area that didn't cost, and yet was a similar experience. And we were right!
Just as we were leaving the parking lot, we met a guy riding a bicycle and asked if we was from the area. Sure enough, he lived just 20 kms or so away. We told him what we were looking for, and he was quick to come up with "Oh, you have to go out to Dunlough Castle!"
