Take a scenic, costal route into the Kingdom of Northumbria, see the Holy Island of Lindisfarne and explore the medieval market town of Alnwick's stunning castle and gardens. The first thing to greet you on your Alnwick Garden adventure and arguably one the most iconic features within 45 acres, the Grand Cascade was one of the original features of the garden. Officially opening in 2001, a wealth of guests have since been dazzled by its beauty or soaked by the catapulting water jets. The garden was thought of by the duchess herself, who wanted the garden to have something that was different from other gardens.
