Pretty much everyone who is going to Kakadu from Darwin stops at the Adelaide River Bridge but that is because they have those tourist boat rides to see jumping crocodiles (baited). But even if you aren’t into such things, it’s worth a stop here to see what birds are around. This is what we saw in about 20 minutes mid-morning.
More Corellas than Crocs!
Specialty of this area is Mangrove Golden Whistler. 
Restrooms and a shop are in the main building.
Typical tourist boat.
