Bespoke Dunnottar Castle & Highland Boundary Geology

Discover one of Scotland's most iconic castles and the great geological fault that shaped its dramatic setting — all in a single half-day from Aberdeen.

This relaxed half-day tour from Aberdeen (with convenient cruise ship pickup at South Harbour) takes you to Dunnottar Castle, the spectacular clifftop fortress that protected Scotland's Crown Jewels. Along the way you'll walk metamorphosed ocean-floor rocks more than 600 million years old, take in panoramic views across the Highland Boundary Fault, and explore Stonehaven's coastal geology — volcanic flows and ancient river deposits side by side.

Your guide is Steve Adams, a working geologist with 45 years of experience and a knack for making rocks come alive. He'll show you why Dunnottar stands exactly where it does and how Scotland's contrasting landscapes were forged along this single great fault line.

No geology background needed. Most of our guests don't have one.

Maximum 6 guests. Pickup from central Aberdeen or Aberdeen South Harbour.

Convenient for cruise ship passengers.
10:00 — Perthumie Bay
A 1km guided walk across some of the oldest rocks on Scotland's east coast — metamorphosed ocean-floor sediments more than 600 million years old. A perfect introduction to Scotland's Highland Terrane and the deep history beneath your feet.
11:30 — Stonehaven Coastal Exposures
A short coastal walk (around 500m) where the geology really comes to life. We'll examine volcanic flows and ancient river deposits side by side — the rocks that built Scotland's central Lowlands.

The grand finale. Explore one of Scotland's most spectacular cliff-top fortresses, perched on a sea stack of ancient conglomerate. Learn the daring story of how Dunnottar protected Scotland's Crown Jewels from Cromwell's army, take in views you won't forget, and discover why this castle could only have been built right here, on this rock. Note: a steep climb is required to access the castle itself.
