Duncansby Stacks
The dramatic Stacks of Duncansby are among the finest sea stacks in the British Isles and one of the most iconic sights in the North Highlands. These towering Great Stacks reach an impressive 60 metres in height and rise from the sea just off the cliffs near John O’Groats.
Just a short walk from Duncansby Head Lighthouse, the stacks are accessed via a scenic clifftop path offering breathtaking views over the Pentland Firth. In addition to the stunning scenery, visitors can enjoy a variety of wildlife and seabirds, including fulmars, kittiwakes, guillemots, razorbills, skuas, and even puffins during nesting season.
A clearly marked coastal footpath leads from the Duncansby Head Lighthouse car park to the stacks. The walk takes around 20 minutes each way, is mostly level, and offers panoramic views of the cliffs and, on a clear day, the Orkney Islands. Sturdy footwear is recommended, especially in wet or changeable conditions.

Explore the Coast: Walk from John O’Groats to Duncansby Stacks
One of the most rewarding ways to reach the stacks is via a 6 km (there-and-back) coastal walk from John O’Groats Harbour. The route follows the foreshore, where you may spot seals, eider ducks with chicks in season, and a variety of seabirds.
Passing through two kissing gates and across a burn occasionally visited by otters, you’ll reach Robert’s Haven, a quiet, sandy beach ideal for beachcombing. Keep an eye out for ‘Groatie Buckies,’ tiny cowrie shells believed locally to bring good luck!
Continuing around the Ness of Duncansby and on to Sannick Bay, the trail climbs to Duncansby Head Lighthouse. From here, a short cliffside path leads you to the breathtaking stacks, where seabirds nest in abundance throughout the summer months. You can return the same way or follow the quiet road back to John O’Groats.
