Hi are you thinking of doing some of the SUW? Nice part if you are, also Moffett is a nice place to vist, there is also a camping site there.
But if you want a hostel then i think Lotus Lodge in Wanlockhead, could be open. Their number is 01659-74544
B&Bs
The Garage Wanlockhead, 0870-2142632
Berries Cottage, 0870-2142638
Rose Lea Cottage, 0870-2142637
I think where you are going has the record for the highest village in Scotland also, plus for a very scenic drive you could vist the old spar.
There are some pics of the area on this website
