Even locals who have passed the Sydney Opera House a thousand times find something new on this guided tour of the building. You step inside Jorn Utzon masterpiece, wander beneath those famous sails and hear the improbable story of how it was built. A guide walks you through the concert halls and foyers most visitors only ever see from the forecourt. Book a morning slot for the softest harbour light, and linger afterwards at Bennelong Point for the classic photo looking back across Circular Quay.
