A lovely walk to take while visiting Jabiru, particularly during or just after 'the Wet', is the path from the Croc Hotel to the old Bowali Information Centre. Although the Centre is now closed, the bitumen path takes you on a liesurely 2km walk through bush and over a creek with an abundance of bush flora and native birds to see along the way.
The cache you are looking for is a small round camoed plastic container with a small log and pencil. Room for very small swaps.
