6. Sydney Royal Botanic Gardens
The Royal Botanic Garden of Sydney is one of the three major botanicals in the city that are open to the public. The garden was established in 1816 by Governor Phillip. It is located in the east of the Sydney Opera House and it overlooks the Farm Cove. The Botanical garden sits on a 30 hectare of land area and is open every day, from Monday to Friday. The great thing about this tourist site is that the entry is free.
