The Royal Botanic Gardens and Domain Trust is responsible for the Royal Botanic Garden Sydney, the Australian Botanic Garden Mount Annan and the Blue Mountains Botanic Garden Mount Tomah. People visit our Gardens for peace, relaxation, education and to learn more about plants and horticulture. Entry to the Garden is free but some special events are ticketed. We provide a range of community events, classes, tours and children's activities led by our expert Education Rangers, Horticulturalists, Volunteers and Specialists.
