There are two ways to access the Isle of Mull via ferry. The more obvious one is the Oban-Craignure ferry. This takes about 45 minutes, and (if I have figured correctly) costs about $180 round-trip, at current exchange rates, for a car and two persons. The less obvious one is to take the 5-minute Corran-Argour ferry (on the A82 about 9 miles south of Fort William), then drive what seems to be about 35 miles to Lochaline, taking the 17-minute ferry trip from there to Fishnish on the Isle of Mull. I think this route would cost about $95 round-trip, plus gas for the extra 70 or so miles of driving.
So, the alternate route would save maybe $70 or so. For me these savings are not decisive (as I thought they might be when I got into this), but I am still intrigued by the alternate route as an adventure, and as a way to avoid Oban, which sounds both crowded and unlovely. Has anyone done the 2-ferry route? I am especially interested in the scenery, and the quality of the road, from Corran-Argour to Lochaline. If the road is decent, and the scenery anything like the jaw-on-floor beauty I'm seeing in pictures of the highlands/islands, then I am leaning strongly toward the alternate route.
