You can visit the ruins of a 16th century tower house at Carsluith Castle, in Dumfries and Galloway, in south west Scotland.
The castle is located just off the A75. It’s open all year and it’s free to enter. You could combine a visit to Carsluith Castle with a pit stop at the adjacent cafe. If the weather is dry, you could sit outside.
There are stone steps to ascend the castle.
The higher you get, the better the views of the surrounding countryside and Wigton Bay.
I had the place to myself when I visited around 10am on a Saturday morning.
