We loved Litchfield and it's spectacular waterfalls, gorges and swimmimg spots. We also loved that it was free (take note Kakadu).
We stayed 3 nights at Florence Falls campground ($13.20 pn) which had toilets, hot showers, kitchen, fire pits and only a short walk to the falls. We were surrounded by trees so it proved a bit difficult to catch sun for the solar panels, but we survived.
Loved Florence Falls, Buley Rockhole, Tolmer Falls, and Wangi Falls, although we didn't swim at Wangi (dozens were) as crocs had been sighted.
We spent a lot of time cooling off in the various swimming spots as it was warm during the day, but thankfully it cooled off at night.
