I posted these posts few years ago, it might be of some interest to you as it is still relevant:
“I personally drove to Palm Valley mid May (2011) without any problem (I have 4WD 6 tonne camper truck), the road has been re-aligned due to floods earlier in the year and in my opinion no problem for beginners to get to the camping area, just take your time. What I donot advise is the 4km drive from the camping ground to Palm Valley itself, there are sections of the track where you (could) need 4WD experience. Having said that just walk the 4 k´s in it’s a fantastic walk and you certainly see a lot more (especially the driver) wild-life etc, I have myself no problem driving in but I always leave my truck at the camping ground and take the walk! There were a number of Brits/Apollo/Maui 4WD drives at Palm Valley.
While you are in Hermannsburg go and visit the "Hermannsburg Mission" founded by two Lutheran missionaries from Germany in 1877. The complex has been well maintained and worth a visit. After that make sure you try the home made "Apple Strudel" that is made from a secret recipe that has been handed down for generations!!!!. “
“If you have a 4WD then "Palm Valley" (Finke Gorge NP) is a absolute must and should not be missed at any cost. Take main road out of town East towards "Gosse Bluff" after about 1 K´s you will find the direction sign on the left hand side. The drive into the gorge approx 16km is just fantastic, you will not be sorry you went. The drive is not hard but can be very rough as you actually drive on the creek bed. The crossing over the Finke River just before the homestead can get quite boggy with soft sand but if you get stuck someone will always come and pull you out. The camp site is set back about 4km from the “Palm Valley” walk and has, believe it or not, flushing toilets and hot showers!! From the camp site there are a number of bush walks, every one is worth doing.
The drive into Palm Valley itself is also very rough and care should be taken that you don’t rip the oil sump out or damage the underneath of your vehicle on the rocks. The hard drive is rewarded with fantastic views and scenery. Once at the car park you will find two walks available, the shorter goes up the valley and back again. My advice is make sure you do the circular walk it is just amazing! you will not be sorry.
Leave your vehicle at the camp ground, get up very early and walk down to the valley instead of driving, loads of bird/wildlife and you can enjoy the scenery at leisure, especially the driver who would normally have to concentrate driving on the track, .
The Palm Valley trip I’m sure will be one of the high-lights of your Oz trip, it’s certainly one of my NT favourites!
One word of warning: On route there is a track that cuts across via “Boggy Hole” to the Ernest Giles Road. The track as the name suggests is very sandy and should only be attempted by experienced 4WD drivers with all the recovery equipment on board! But saying that, the trek is well worth doing (I enjoyed it) if you are capable but ALWAYS check with the ranger before setting off.
If you have no 4WD there are one or two day tours out of Alice but I have no idea of the cost.”
Remember track conditions do change often at short notice, you can get up to date information at Hermannsburg Police Station, at the petrol station or phone 1800 246 199 for current road conditions .
My personnel opinion is that the track from the highway to the Palm Valley camp ground is OK for an un-experienced 4WD driver, if you are not sure of yourself just wait at the start of the track till another 4WD comes along and ask if you may tag along!

Enjoy your trip you will not be sorry!
