The Blue Mountains, 90 minutes drive outside Sydney, are named rather literally: the sun here creates a distinct blue haze in the hills and valleys when it merges with drops of eucalypt oil that the millions of eucalyptus trees in the hills disperse. There's no more luxurious way to see the haze than from Lilianfels Blue Mountains Resort and Spa, a lavish Victorian country estate perched on high cliffs overlooking the valleys. Its 83 contemporary-plush rooms have stunning views of the valley, while plush living rooms with blazing log fires and antique furniture recall the aristocratic homes of old England. Restaurant Darleys serves exquisite Modern Australian cuisine made from organic home grown produce and activities from country walks, billiard games, boules and state-of-the-art spa treatments - try the floatation tank - get you relaxed and healthy. Head for the hills.
