Welcome to the Royal Botanic Gardens Sydney, an oasis of 30 hectares in the heart of the city. Wrapped around Farm Cove at the edge of Sydney Harbour, the Gardens occupy one of Sydney's most spectacular positions. Established in 1816, it is the oldest scientific institution in the country and is home to an outstanding collection of plants from Australia and overseas. From the provocative rare and threatened plants of the world to the romantic rose garden, the themed garden areas show the diverse beauty of nature. Special features include: Cadi Jam Ora - First Encounters is a garden display that remembers and acknowledges the Cadigal - the original inhabitants of Sydney's city centre - and their relationship with this land. Aboriginal Heritage Tours of the Royal Botanic Gardens run 10am Fridays or by request for groups. Free guided walks daily 10:30am from the Garden Shop.
