Don a headset, a safety cord and a dandy gray jumpsuit and you'll be ready to embark on an exhilarating 3½-hour climb to the top of Sydney's famous bridge. The priciest climbs are at dawn and sunset. A cheaper, 90-minute "sampler" climb (to a lower point) is also available, as are "express climbs," ascending to the top via a faster route (2½ hours).
