A few friends and myself are thinking of spending a few days around Thredbo Or Mt Buller in summer to do some Mountain Biking. I have checked the www.rawnrg.com.au site and its very expensive just for one day to use the chairlift...has anyone been down there and is it worth it? Besides the long downhill on thredbo are there many other riding options? We are looking to spend 4-5days down there...what else is there to do???
