I formed a Cruise Critic roll call group to participate in Offroad Dreaming's cruise ship group tour to Litchfield National Park. Our guide, Adam, was superb. We visited three waterfalls and had the opportunity to swim at each one. A delicious lunch was served complete with tablecloths and silverware. Snacks were also provided. Our guide stopped the van when he saw a frilled lizard crossing the road and for an emu family with three chicks crossing later. Best wildlife in the wild I saw on our entire trip! I was very pleased with this excursion and highly recommend it. The schedule is modified for cruise ship passengers. You are picked up at the ship upon arrival and returned in time for departure.
