We visited Kakadu in late May and did the Yellow Water Cruise on 30/5/12. By this stage we had already done the 'Spectacular Jumping Crocodiles' tour at Alligator River (on the way to Kakadu from Darwin) as well as the Guluyambi Boat Tour at Ubirr. We almost didn't bother to do the Yellow Water Cruise as we figured we had done enough boat cruises and it would probably be much the same as the others. We are so glad we ended up doing the cruise.
The Yellow Waters was a beautiful wetland area and quite different from what we had seen at Ubirr. One of the main differences was that there was such a great variety of birdlife at Yellow Waters which we had not seen at all on the Guluyambi tour. Our guide Isaac was very knowledgeable about the birds and other wildlife. He had all sorts of interesting stuff to tell us, including the aboriginal lore he had picked up from his housemate who was one of the local aboriginal people.
We even got to see a fight between two male crocs (over turf or mates I guess), which apparently is a rare event that we were very lucky to witness! I'd definitely recommend doing this cruise while visiting Kakadu National Park.
