Glamis Castle, located in the foothills of Angus Glens 45 minutes north of Perth and considered the most beautiful castle in Scotland, has been the ancestral home of the Earl of Strathmore for more than 600 years and is the childhood home of the Queen Mother. The gardens and grounds are beautiful year-round. In spring, swaths of daffodils line a mile-long avenue. In summer, the brilliant hues of flowering rhododendrons and azaleas light up the grounds. In autumn, the abundance of trees ensures a glorious spectacle of fall color. Garden highlights include an Italian garden laid out by Countess Cecilia, the Queen Mother’s mother, in 1910, a nature trail, a Pinetum featuring a variety of exotic trees laid out by the 13th Earl in 1870 and a four-acre brick-walled kitchen garden. The gardens are open until Nov. 3.
