This 4.8-hectare walled garden incorporates a series of magnificent green spaces surrounding the breathtaking Grand Cascade – 120 separate jets spurting some 30,000L of water down 21 weirs. Half a dozen other gardens include a Franco-Italian-influenced Ornamental Garden (with over 15,000 plants), Rose Garden and fascinating Poison Garden, home to some of the deadliest – and most illegal – plants in the world, including cannabis, magic mushrooms, belladonna and tobacco.
Enveloped by – but not in – the treetops, the timber-lined Treehouse restaurant serves Modern British cuisine.
