We were just there this past weekend (Oct) and wanted to put in a big PLUG for the park!
Reasons we loved Darlington Park:
The onside managers (Judith and David) are so incredibly helpful and friendly!
There are platypus in the creek (and turtles) and a rope swing
Plenty of shallow "rapids" for the kids
Extremely clean amenities - toilets and BBQs
Playground for the kids and a cricket oval for sport or kite flying
Close to great walks at Lamington NP
CHEAP! 13.50 maximum for a family ($5 per adult, 2.50 per child)
Wonderful weekend and highly recommended
