To get around the area, most locals walk. Expect to see lots of other pedestrians around Oxford St, William St and Darlinghurst Road most times of the day and night.
Kings Cross can be a jam for cars both in peak hours on weekdays, and late at night.
Almost everywhere has either limited parking one to two hours or parking meters. Expect to pay for parking if you drive. Moore Park has three hours free parking, except during sporting or large entertainment events, when you can expect to pay a larger flat fee.
