Towing to coongie lakes & cullymurra w'hole

Cullymurra yes . Can't say about Coongie Lake as I hav'nt been there but I would think so.

Coongie Lakes is sometimes a NO. Check with National Parks at Port Augusta. Are you planning to go there soon - because both places are out due to flooding.

Did Coongie 2 years ago and it was 100k in and out on hard packed corragated sand.

Depends on your van - how long is it ? - if its compact AND it handles corrugations well, then you only have a couple of bumps, heaps of corrugated sections and some soft sandy spots (which vary due to water levels and detours etc). 90 Km each way - Spoke to a caravan industry bloke the other day who said a customer described their 24 foot caravan as off-road - there are practical limits.

Lovely spot up at Coongie but keep in mind it can get amazingly cold if the wind comes off that water, and it is a campfire free zone. Closed currently seeing the Cooper is up - Western end of Cully is the only practical spot currently - might be squishy up there for quite some time - that alluvial clay is something else when it gets wet - have to talk to the locals before you plan.

Regarding SOFT sand on the tracks for both your destinations.
Cullymulla is no problem at all.

When i was last at Coongie, dunes on the way were no problem. The track/road was no problem until about 1 km from the nat. parks camp/picnic area at the lake.
The small dune there would not stop a 4x4, but would stop a 2 wd, and may slow you down a bit unless you are prepared.
Even so, you could camp around there and walk 1 km to the lake, or camp back a bit at Kudriemitchie and drive to the lakes.

If you cross that dune to the "main area", and want to camp in isolation on the lake shore (and it may be too full of water for this) you need to cross a second dune which is probably a bit steeper.

Take your van out there if it is robust and camp where it suits you at the time. I can't see problems if you are sensible.

Was at Coongie lake on new years day this year.(bit warm 'bout 54c!)
Track was a bit rough in places(although our idea's of "rough" might be different), but if you went slow towing your caravan seeing as it's an off-roader you should have no problems. Might be "fun" if the track was wet, but otherwise you'd be fine.
Not sure about going around the 4wd only dunes at the end but you can still
park up near the lake without having to 4wd.

Hope this helps.
