In addition to the castle itself, visitors to Leeds can also experience:

The Maze - Planted with 2,400 yew trees in 1988, the maze at Leeds Castle challenges visitors to reach the panoramic central viewing point. (No need to fear getting lost; staffers perched high in the center help to guide the direction-impaired through this topiary castle.)
The Aviary - More than 100 species of rare and colorful birds including macaws, cockatoos, and toucans are housed in the outdoor aviary.
The Dog Collar Museum - Certainly one of the world's most unusual collections, the Dog Collar Museum displays nearly 100 antique dog collars spanning five centuries. Collars dating from the 15th, 16th, and 17th centuries were designed to protect a dog during a time when wolves, bears, and wild boar roamed the forests of Europe and the vulnerable throats of hunting dogs needed protection with broad iron collars bristling with fearsome spikes. The Dog Collar Museum also houses Leeds Castle's small gift shop.
Culpeper Garden - This quintessential English garden features neat box hedges enclosing traditional colorful perennials and fragrant annuals such as roses, pinks, lupins, and poppies.
Restaurant - More than 8,000 bottles of wine are produced each year from the castle vineyard. Award-winning Leeds Castle wines are sold exclusively in the castle restaurant and shops.
