The Pebbly Beach Holiday Cabins offer about the most remote cabin experience in driving distance from Sydney. We took the train to North Wollongong, rented a car at Thrifty Car Rental from manager Bill (exceptional human being). Drove the other 3 hrs...
Yvonne and Stuart McFarlane are the hosts, and this is their website: http://www.pebblybeach.com.au/.
Only ten cabins, plus theirs and another one (caretaker) and that's it... and then the two mobs of kangaroos, goanna lizards, birds, possums and serene beach/forest valley like a scene from a dream.
One word: EPIC. Epic people, epic place they run, epic critters, and from my VERY limited kangaroo knowledge/experience, some pretty tame and lovable creatures. Check out our movie, too, on youtube, simply called "Pebbly Beach, Australia". A lovely place and the cabins are so clean, so well-maintained, comfy, great views, was only 125/night, and a magical location that I truly hope to return to one day. The McFarlanes are OUTSTANDING. Cheers, Yvonne and Stuart.
