Wishbone Therapy Farm
Looking for a quiet country retreat in the beautiful Pyrenees Ranges for the weekend? Wishbone is rolling out the welcome mat to all you campers and caravaners out there!! Just let us know when you would like to come stay and we will be happy to have you FREE or charge. There is only one catch... for every day that you stay you give us a helping hand for a short spell. It might be building something, fixing a fence or feeding the cow. Whatever floats your boat!! We are only 2 hours from Melbourne, just 30 mins from the Grampians and surrounded in wineries so plenty to see and do. Children and pets are always welcome!! Simply send us a PM or call Sherry on 0410 483 763 to make a date.
