We were in Kakadu for four nights at a great campsite in Jabiru. We trundled around the sites (including this pretty stunning lookout over the wetlands near Ubirr) but really needed at least a week or more, to see everything. We had also come off the back of six days of constant driving where we camped for one night and moved on in an attempt to gt through to the Top End pretty quickly. In consecutive nights we stayed at Emerald, Longreach, Mt Isa, Barkly Homestead, Daly Waters, Katherine and then Kakadu.
