I was in Glasgow for a day. I wanted to visit two near distilleries, glengoyne and auchentoshan. However nobody was able to direct me to the right buses and bus stops. Get that info before coming and reserve online for your tickets. Also, do visit the Pot still, a wonderfull little pub with hundreds of whiskies. The hop on hop off sightseeing tour makes for great pictures as the architecture is really interesting.
