Catalina Park commonly known as The Gully is a beautiful piece of land situated in Katoomba and is also known as the Katoomba Falls Creek Valley. The Gully forms the headwaters of the Katoomba Falls Creek and is therefore part of the Warragamba Catchment area that provides Sydney’s water. It is an ecologically and culturally sensitive place. The Gully was declared an Aboriginal Place on 18 May 2002. The Gully in Katoomba became the largest Aboriginal Place in NSW.
Equally as beautiful, The Kalkari Discovery Centre, is located near Ku-ring-gai Chase National Park western boundary, one of Sydney's less-known natural gems. The park is the second-oldest in the country, established in 1894 and preceded only by Royal National Park, which was founded in 1879 and lies to the south of Sydney.
