Are you from out of town and looking for accommodation while attending the Kowen Trail Run? Why not stay at Queanbeyan: http://www.visitqueanbeyan.com.au/accommodation
Or if you’d like a more rural feel, try Bungendore – just as close as Queanbeyan but to the east of Wamboin http://www.bungendore.com.au/bungendore-accommodation/
Both Queanbeyan and Bungendore are closer to Kowen Forest than Canberra and accommodation rates are FAR more reasonable!
Also, why not try searching for homes in Wamboin, or neighbouring areas of Bywong, Sutton, Bungendore and Queanbeyan on Airbnb at https://www.airbnb.com.au
