There is a quiet way via the lochgoilhead road (B839 and B828 i think) to the carpark at the top.. After that if you are on a road bike you probably need to join the new road but it is all downhill from there and the traffic isnt too much of a problem with the speed you are going at. There is an alternative way down on the old road though if on a bike with wider tyres, should be ok on a tourer. If coming the other way do that in reverse
