Harrington Forest is a bushland reserve in Harrington Park, managed by Camden Council. It protects a patch of critically endangered Cumberland Plain Woodland. Its highlight is the Nest Box Trail: ten nest boxes, decorated by local school and preschool children, are mounted in the old gum trees, and visitors try to spot them all. Most of the trail follows a sealed path. It’s a free, easy nature walk with a fun “treasure hunt” to keep everyone engaged.
