About The Alnwick Garden
The Alnwick Garden is one of the most ambitious garden projects in Europe, created by the Duchess of Northumberland. Spanning 12 acres adjacent to Alnwick Castle, it features the spectacular Grand Cascade — the largest water feature of its kind in the UK — along with the famous Poison Garden (home to some of the deadliest plants in the world), a beautiful cherry orchard, ornamental gardens, and one of the world's largest treehouses. The garden hosts regular events, exhibitions, and seasonal activities throughout the year. There is also a cafe and gift shop. A wonderful day out for all ages.
