#4/#6 Aberfoyle, Duke's Pass, Lochearnhead, Killin, Kenmore, Aberfeldy, Sma' Glen, Crieff. Did this on Thursday, if you only do one don't miss this. Loch Long route great if you get it empty but about only one passing place. If staying near Glasgow, take an evening run for Fish & Chips in Inveraray. Great road south of Lochgilphead, call in to Crinan, down to Campbeltown back up to Tarbert take the ferry to Port Avadie then over to Hunter's Quay and ferry over to Gourock.
