The camp is only 2.5 km from the turnoff, which has an example of one of the original underground catchment tanks used for sheep grazing. There is a lookout only a short walk from the camp overlooking the lake.
Firewood is scarce, and there are no facilities.
There are some good tracks in the Wilpena area. Make sure you do Skytrek.
Arkaroola is my favourite part of the Flinders, Waraweena is second. Have a meal at the Prairie Hotel (Parachilna Pub), also owned by the people with Pinch of Salt track.
What part of Mt Remarkable NP are you staying at, Mambray Creek or Alligator Gorge? Mambray is better in my opinion.
If you are doing the Lake Torrens track from Farina (good camp ground with flushing toilets and a donkey shower) it may have some areas where caution will be needed with the caravan. Some good camping when you get to the sand dunes north of Andamooka.
This track can be quite slippery after rain in the salt flat areas, and you can get your permit from Wichelina Station along the way.
A few photos of the track around the top of Lake Torrens are attached.
