We stayed 2 nights in early December. It was a very good location to explore the Cradle Mountain and nearby. We are impressed by their effort to live off the grid and be self-sustaining, yet maintaining comfortable lifestyle. Leaving some land for the use of wildlife and prevent invasive species is a respectable idea.
Driving on the driveway at dusk feels almost like night safari, we spotted wallabies and rabbit. Unfortunately we didn't get to see the platypus. My kids love the dogs; the goats are friendly too.
There are basic kitchen facilities. We found it a little cold during our stay (though supposedly summer but temperature were around 8-18C if not mistaken), it didn't occur to us to ask for the fireplace to be lit! Limited eating places nearby so do plan ahead.
I'd highly recommend this place!
