Bring something to swim in when you come to the Day Spa at The Observatory Hotel and make sure schedule plenty of time because this is one of the spas in Sydney you probably won’t want to leave. It’s all too easy to spend hours floating in the spa’s wet area, featuring Romanesque columns, a tranquil 20-metre indoor pool featuring a fibre-optic, twinkling ceiling representing the Southern Hemisphere sky at night, sauna and steam rooms. This is one of the most opulent spas in Sydney and treatments are equally luxurious, using La Praire products. Rooms feature individual showers and the spa menu features everything from a simple manicure to an all-day pampering session. The spa caters well to couples and men, too – try the Gentlemen’s Rescue if you fancy several hours of being smothered with La Prairie Skin Caviar massage followed by a Swiss Cellular facial. Massages are dreamily executed, but why settle for one therapist when you can have two? The Observatory Four-Hand Therapy means there are four hands kneading, pummelling and soothing the muscles, nudging away even the most stubborn laptop shoulder knots.
