You don't need a permit, just look out for the tourist buses. More interesting by far is the Mereenie Loop Rd which winds around and takes you in through the West MacDonnel Ranges. You can puchase the $2.00 pass at Kings Canyon resort (go to reception to the south of the road as you enter the resort). This is an easy drive and takes you through much more interesting terrain. Always use the road less travelled :-). Be prepared to be blown away by Kings Canyon if you haven't been there before. Give yourselves plenty of time.

Thanks for that Bob. What's the Mereenie Loop Rd like. I'd say we are moderately experianced offroaders but are not setup for anything to serious or remote on this trip.
