Exmouth to Gnaraloo

There is but you can't use it.
The gates are locked just north of gnaraloo bay and again on the Waroora southern boundary.
It's a bit of a blot cos it's a nice drive through there in winter. Not so nice in hot weather but.

You can drive from Exmouth down through the Cape range nat park down as far as Coral bay along a coastal track, which is also a nice drive in winter so long as you're not rushed. It's a bit bumpy in places but if you sit on about 20 to 30kphr it's pretty good.
All gates are unlocked on this track and mostly are left open.
You will have to wait til low tide at Yardie creek though because it has been open to the ocean for the last few years and deep at high tide. Usually only a few inches deep or even dry at low tide. Get a tide chart before you cross and preferrably cross on a falling tide in case you get stuck. It gives you a bit of time to get yourself out.

p.s. I've never used booties but some wusses use them to stop urchin spikes in the feet. You won't need them at the dunes because that seems to be urchin free for the last few years, so long as u go in and out in front of the shack.
Anyway, I think urchin spikes and stonefish would probably go straight through booties.
You would really need hob nail boots and they would just look plain silly.

Thanks for the reply.

I think the main road looks the easer option.

I'm glad to hear that you think booties are a waste of time. I've never worn them, I've surfed at Dunes before with no problems but saw some people sporting them. Booties would probably cause me to not stick the takeoffs and head over the falls head first onto the reef, a possible spike to the foot would then sound like a better option.

Cheers
