Howick Hall Gardens make a worthwhile detour from Alnwick if you have a car and want something quieter than the castle circuit. The estate is best known as the ancestral seat of the Grey family, including Charles, 2nd Earl Grey, whose name lives on in the tea blend.
The draw is the garden rather than the house: spring bulbs, a formal terrace, woodland walks, and paths that run toward the Northumberland coast. It rewards slow wandering, especially in rhododendron season, and pairs naturally with a drive along the coastal villages north of Warkworth.
