About 16 miles west of Aberdeen, Crathes Castle was once the home of the Burnett family and is one of the best-preserved castles in Britain. Keepers of the Forest of Drum for generations, the family acquired lands here by marriage and later built a castle, completed in 1596. The National Trust for Scotland cares for the castle, which is furnished with many original pieces and family portraits. Outside are grand gardens with calculated symmetry and clipped yew hedges. Make sure you browse the Horsemill bookshop and sample the tasty baked goods in the tearoom. There's an adventure park for kids, and the staff organizes activities that are fun and educational.
