Duncansby Stacks
Highlight • Natural Monument
Duncansby Stacks are two visually-impressive 60 m high sea stacks (offshore pinnacles of steep-sided rock) located to the immediate south of Duncansby Head (the most northeasterly part of the British mainland) in Caithness. A third rock promontory called Thirle Door is in the process of becoming a stack but still remains attached to the mainland.
The offshore stacks are remnants of where the coastline used to be. They were formed by sea and storm weathering and have existed for at least 6000 years. The stacks are made of a coarse-grained sandstone rock that dates from the Devonian geological era 385 million years ago. The tallest stack is called the Great Stack and is actually higher than the nearby mainland.
The grassy path that descends south from Duncansby Head and the Geo of Sclaites provides superb views of the Duncansby Stacks and of the Thirle Door arch! The two stacks and Thirle Door will appear nearly-aligned in a row.
An additional highlight of viewing Duncansby Stacks is that - depending upon season - you may see them covered by large seabird colonies.

Tip by
The Clett Sea Stack
Highlight • Viewpoint
Be aware that the path is on the outside of the fence passing along some high cliffs, at one point quite close to the edge. If vertigo isn't a problem, when looking down at times you can spot sea caves at the bottom.
Tip by
Bucholie Castle Ruins
Highlight • Historical Site
The castle stands on a 30-metre-high peninsula and is separated from the land by a moat about 2 metres wide and 3 metres deep. Only the high western wall and part of the south wall of the castle remain.
The headland in front of the gatehouse as part of the keep tapers to an extremely narrow point, with unstable cliffs on either side of an unstable step to the entrance. Entering the castle is therefore too dangerous.

What a great little castle. Amazing to see it still standing after so many years. Very cool little place to visit and explore the ruins - never quite seen anything like it.

Bucholie Castle – Forgotten ruin on a cliff edge One of Caithness’s most dramatic, yet least visited castles, this 15th-century ruin sits on a narrow headland overlooking the North Sea, a few miles south of John O’Groats. The walk to it (approx. 20 mins from the A99) takes you across quiet meadows and ends with a spectacular view of the remains.

Parts of the path are overgrown (be careful of ticks, I had to flick 7 of my clothes) and potential for slipping near to cliff edges, so care mist be taken. Otherwise very enjoyable, even if i did take a few wrong turns following more used animal tracks.

Bucholie Castle or a predecessor is said to have been built around 1140 by Sweyn Asliefson, a Norse pirate and privateer. However, the buildings visible today were built by the Mowat family, who received the land from King Robert the Bruce. The castle stands on a 30-metre-high peninsula and is separated from the land by a moat about 2 metres wide and 3 metres deep. Only the high western wall and part of the south wall of the castle remain. The headland in front of the gatehouse as part of the keep tapers to an extremely narrow point, with unstable cliffs on either side of an unstable step to the entrance. Entering the castle is therefore too dangerous.
