Duncansby Head & the Duncansby Stacks – Scotland’s Most Spectacular Sea Stacks
If you think John o’ Groats is the highlight of Scotland’s far north-east, you’re in for a surprise. Just two miles further along the coast lies Duncansby Head – the true most north-easterly point of the British mainland – and it puts its more famous neighbour firmly in the shade. The real stars here are the Duncansby Stacks, towering pyramids of ancient sandstone that rise dramatically from the sea like something from another world. Combined with a charming Stevenson lighthouse, jaw-dropping cliff scenery, and abundant birdlife, this is one of the most rewarding short walks you’ll find anywhere in Scotland.
History and Background
Duncansby Head (Scottish Gaelic: Ceann Dhunngain or Dùn Gasbaith) juts out into the North Sea at the very tip of Caithness, with the notorious Pentland Firth to its north and west and the Moray Firth to its south. Despite John o’ Groats claiming the fame, it’s actually Duncansby Head that holds the title of the most north-easterly point of the Scottish and British mainland – and it probably exceeds John o’ Groats’ distance from Land’s End by a good mile or two.
The headland and the surrounding 6.5-kilometre stretch of coast running south to Skirza Head is designated a Site of Special Scientific Interest (SSSI), and it’s not hard to see why. The coastal scenery has been shaped by continuous marine erosion and weathering over millennia, creating deep geos (coastal ravines), sea caves, blowholes, and of course the famous stacks themselves.
The Duncansby Stacks are composed of Old Red Sandstone, a rock type dating back roughly 400 million years to the Devonian period. Over thousands of years, the relentless forces of wind and wave have carved these isolated rock towers from the mainland. There are actually four stacks in total: the Great Stack, which at over 60 metres tall is even higher than the adjacent cliffs; the Witch’s Hat Stack; The Knee; and The Little Knee. In front of the stacks sits Thirle Door, a natural sea arch still attached to the mainland that will, given enough time, collapse to form yet another stack. The stacks are thought to have stood in their current form for over 6,000 years.
The headland is marked by Duncansby Head Lighthouse, a distinctive square concrete tower designed and built by David Alan Stevenson in 1924. The Stevenson family were the great lighthouse builders of Scotland, responsible for over 200 lighthouses around the coast, and David Alan was the last of the line to be connected with lighthouse building. The family’s most famous member wasn’t an engineer at all, but the writer Robert Louis Stevenson, whose childhood trips to remote lighthouse locations with his father inspired stories like Kidnapped and Treasure Island.
Standing only 11 metres high, the lighthouse doesn’t look particularly imposing on its own – but perched on a cliff 67 metres above sea level, its white light flashes every 12 seconds and is visible 22 nautical miles out to sea. The light was desperately needed. The Pentland Firth, the strait separating the Scottish mainland from Orkney, earned the fearsome nickname “Hell’s Mouth” among sailors. The tidal streams here create dramatic and dangerous races and eddies that can reach speeds of up to 10 knots, with each named individually – the Swilkie, the Bore of Huna, the Wells of Tuftalie, the Duncansby Bore, and the Merry Men of May.
The lighthouse has had its share of drama too. During the Second World War, on the eve of the invasion of Norway, a German bomber machine-gunned the lighthouse. Fortunately, nobody was injured and no damage was caused. The lighthouse was automated in 1997, and sadly the keepers’ accommodation had to be demolished due to asbestos contamination, leaving just the building attached to the tower itself. In 2024, the lighthouse celebrated its 100th anniversary, marked by a special light and sound show organised by Lyth Arts Centre.
The area is also a haven for wildlife, particularly seabirds. During spring and summer, the cliffs and stacks come alive with thousands of nesting puffins, guillemots, razorbills, kittiwakes, and fulmars. The waters below are rich in marine life too – seals are regularly spotted lounging on the rocks, and dolphins and even orcas occasionally pass through these waters. Duncansby Head is one of the official watching locations during the annual Orca Watch week at the end of May.
Our Visit
Getting There
My wife Janette and I arrived at Duncansby Head after a short visit to John o’ Groats. We’d been keen to see the famous signpost, but if we’re being honest, Duncansby Head was the real reason we’d driven this far north. From John o’ Groats, you simply take the single-track road signposted off the A99 (opposite the post office) and follow it for about two miles until you reach the lighthouse car park at the end of the road.
The car park is free and has space for cars, campervans, and even coaches, though it’s not the biggest and I can imagine it filling up quickly in high summer. We visited on a gorgeous clear day and there were a handful of vehicles already there, including a couple of motorhomes. It’s worth noting there are no facilities at all here – no toilets, no café, no shop – so make sure you visit the facilities at John o’ Groats before heading out.
The Lighthouse
The first thing that strikes you as you arrive is the view. Looking north and west from the car park, you can see across the Pentland Firth towards the Orkney Islands, and back along the coast to John o’ Groats. On our clear day, the views were absolutely stunning – the deep blue of the sea stretching to the horizon with the low-lying shape of Orkney beyond.
We had a good look at the lighthouse itself, which sits in a slight dip on the clifftop. It’s a smart, compact building – white-painted with golden-yellow trim – and the distinctive square tower gives it a character quite different from the typical round Scottish lighthouse. You can’t go inside, but there’s an excellent information board nearby that tells the story of the lighthouse, the Stevenson family, and the treacherous waters of the Pentland Firth.
From the lighthouse, we could also pick out what I believe to be the Pentland Skerries out in the firth, with a lighthouse clearly visible on Muckle Skerry. It really drove home just how exposed and wild this stretch of water is.
Walking to the Stacks
As impressive as the lighthouse and the northward views are, the real magic at Duncansby Head lies to the south. A signpost near the lighthouse points the way, and we set off along the well-trodden grassy path that follows the cliff edge towards the stacks.
The walk is only about three-quarters of a mile each way and the terrain is relatively gentle, though the path is on grass rather than a formal surface and can be muddy after rain. There’s a wire fence running along much of the cliff edge, which gives some reassurance, but you still need to take care – the drops are sheer and considerable. We passed sheep grazing contentedly on the headland, completely unfazed by the visitors tramping past.
As we crested the rise behind the lighthouse, the first hint of the stacks appeared on the horizon – just the tips poking above the clifftop. With every step the view opened up further, and before long we had our first proper glimpse of the Duncansby Stacks in all their glory. I don’t think either of us was quite prepared for how dramatic they are in person. Photos simply don’t do justice to the scale of these things – enormous jagged pinnacles of layered sandstone rising vertically from the sea, with the massive cliffs continuing south beyond them.
The Stacks Up Close
We spent a good while at the main viewpoint, soaking up the scene and taking far too many photographs. The Thirle Door sea arch is clearly visible at the base of the cliffs, and you can easily make out the individual stacks with their distinctive pyramid shapes coming to sharp points. On a calm, clear day like ours, the sea was a beautiful deep blue, and the sunlight catching the water around the stacks made for some gorgeous photo opportunities.
Rather than turning back at the first viewpoint, we continued south along the coast to get closer to the stacks and see them from different angles. This is well worth doing if you have the time – the perspective changes dramatically as you move along the clifftop, and you get much closer to the formations. The path descends to a lower section of coast before climbing again past the stacks, and from the higher ground beyond you can look back for a completely different view with the stacks silhouetted against the cliffs and sea.
I also managed to get the drone up for some aerial shots, and the view from above really puts the scale and beauty of the stacks into perspective. From the air you can see how the stacks were once part of the mainland, gradually isolated by the relentless erosion of the sea over thousands of years. It’s a humbling reminder of the raw power of nature.
After thoroughly exploring the area around the stacks, we walked back across the headland to the car park. The return walk is just as enjoyable, with the lighthouse gradually coming back into view ahead and the wide open expanse of the Caithness landscape all around. We allowed about 90 minutes for the entire visit, which gave us plenty of time to explore at a leisurely pace.

Frequently Asked Questions
Is Duncansby Head free to visit?
Yes, Duncansby Head is completely free to visit. The car park is free, and there is no charge to walk to the stacks or explore the headland. It’s open at all times, though overnight parking is not permitted between 10pm and 8am.
How long is the walk to the Duncansby Stacks?
The walk from the lighthouse car park to the main stacks viewpoint is approximately three-quarters of a mile (just over 1km) each way, and takes around 15–20 minutes at a comfortable pace. If you continue further along the coast to see the stacks from different angles, allow 60–90 minutes for the full round trip.
Is the walk suitable for children and older visitors?
The terrain is relatively gentle with no steep climbs, so the walk is manageable for most fitness levels. However, the path is on grass (not surfaced), can be muddy after rain, and runs close to unprotected cliff edges in places. Children should be closely supervised, and sturdy footwear is recommended.
Is Duncansby Head wheelchair accessible?
Unfortunately, the walk to the stacks is not wheelchair accessible. The path is on uneven grass and turf with no formal surface, and there are some boggy patches. The car park and the area immediately around the lighthouse are on firmer ground, and you can enjoy views north towards Orkney from there.
Are dogs allowed at Duncansby Head?
Dogs are welcome but should be kept on a lead at all times, as there are sheep and other livestock grazing on the headland. The cliff edges are also a hazard for off-lead dogs.
Are there toilets or a café at Duncansby Head?
There are no facilities whatsoever at Duncansby Head – no toilets, café, or shop. The nearest facilities are at John o’ Groats, approximately two miles away, where you’ll find public toilets, several cafés, and a visitor centre.
When is the best time to visit Duncansby Head?
Duncansby Head is impressive at any time of year, but for the best wildlife viewing, visit between late spring and early summer (May–July) when the seabird colonies are nesting. For photography, sunrise and sunset offer the most dramatic lighting on the sandstone stacks. A clear day is ideal to enjoy the views across to Orkney.
