Explore one of Scotland’s most stunning castles and gardens, along with the geological history of the Dee Valley and Highland Boundary, all within a half-day trip from Aberdeen.

This leisurely half-day tour, with convenient cruise pickup at Aberdeen South Harbour, takes visitors to Crathes Castle, a 16th-century tower house at the entrance to Royal Deeside, renowned for its walled gardens and ancient yew hedges. During the journey, participants will walk on metamorphosed ocean-floor rocks over 600 million years old, enjoy panoramic views across the Highland Boundary Fault, and discover Stonehaven’s coastal geology.

The guide, Steve Adams, is a geologist with 45 years of experience and a talent for bringing rocks to life. He will explain why Royal Deeside appears as it does, how the River Dee shaped its valley, why Crathes is located precisely where it is, and how Scotland’s diverse landscapes were formed along this significant fault line.
