Ever wonder how the other half lives? This annual event grants public access to some of Amsterdam's most beautiful private gardens. A single pass buys entrance to the grounds of a host of canal homes dating from the 17th, 18th and 19th centuries. The well-kept gardens showcase a variety of design styles and also offer intimate concerts, sell garden decor and furnishings, and sometimes provide light refreshments. A canal boat is available to shuttle visitors from garden to garden.
