Dunns Swamp, or Ganguddy as it is known to local Aboriginal people, is a beautiful, serene waterway on the Cudgegong river in Wollemi National Park. The waterway was created when Kandos weir was built in the late 1920s.

Ganguddy caters for tent, campertrailer, and caravan camping.

There are some great bushwalks in the park.

Kayak tours and hire of kayaks and stand up paddle boards is available on weekends and daily during school holidays, from September to April.
