Ubirr is well worth a visit to when around Kakadu. Aboriginal drawings can be seen on the short and easy walk. There are signs along the path that detail what has been drawn.
If you're able to walk up the rocks, it is well worth getting to the top and seeing the view. You get 360 degree views all around, very green on one side and a lot of rocky hills around also.
I think the walk to the top probably looks harder than it is, there aren't many big steps to do, the path is quite good.
