Historic, picturesque, and relaxing, the Sydney Royal Botanic Gardens cover 74 acres (30 hectares) running along the harbor from the Sydney Opera House to Woolloomooloo. A true inner-city oasis, the gardens combine exotic plantings from Europe, tropical rainforest, woodland, flowers, grasses, the Indigenous First Encounters garden, and rare horticultural exhibits. A program of events includes activities, workshops, courses and lectures, plus there are entertaining guided walks throughout the year.The gardens are laced with leafy walkways and harbor lookouts, and they also boast a fernery, camellia garden, palm grove, and herb garden. For a walk through history, the Mrs Macquaries Bushland Walk traces a path along the coast, re-creating the landscape as it appeared when the early settlers arrived in Sydney in the early 19th century. Don't forget to stop off at Mrs Macquarie's Chair, a bench carved out of sandstone, to get amazing views of the Sydney Harbour.
