I will be traveling to Darwin next week from the US. Unfortunately, I only have 5 days in Darwin so can only allow myself a day trip to Kakadu. I know that is not ideal at all, but I figure it’s best to see it for a few hours rather than nothing at all. Unfortunately we don’t get enough vacation days over here in the US. I was looking at tour options from Darwin however I consider myself a fairly advanced hiker and am concerned I might be disappointed as I want to spend most of my time on walks. I will have access to a 4WD vehicle during my stay, so I am considering driving myself. I am most interested in Gunlom and Jim Jim falls, however I am wondering the feasibility of getting to these in only one day. Are there any other walks closer to Darwin to offer similar experiences (moderate/difficult)? What regions would those be in? Can I drive straight do the walks or is there a centralized entrance I need to find and enter through? Basically, is it feasible to do a moderate difficulty hike in one day, self-driving, and if so, which would you recommend? Or, am I better off doing a guided tour with the easier walks? Any advice is appreciated. I really want to work Kakadu into my trip but I also know the time constraints I’m working under won’t do as must justice as I’d like.
