Saw this on the Beeb today, Calmac launching a summer ferry from Ardrossan to Campbeltown article here.
Bearing in mind Ardrossan is under 2 hours away on the train, and previously you would have had to go across to Brodick, around Arran then across from Lochranza to Skipness, you can now go direct to south of Kintyre and then up the east coast on the B-road. From there Islay and Jura are but a few hours away on the ferry.
New opportunity for some shorter touring without having to do the dull bit of "getting there".
I may factor this into my summer plans.
