I have a gpx file for fuel round there - most involves at least a short walk up a beach.... It's on the home PC - will try to remember to post it tonight.
Re. food & places to go - see above!
If, however, you fancy a trip to the middle of nowhere , a wee trip / play through the falls at Connel (mind the canoes on the way past!) and you have a fair few miles of Loch Etive solitary to play with - plenty of places to drift & picnic , just don't do it on a day with a northerly or southerly wind unless you are wrapped up well!
As an aside - are you planning on launching at Linnhe & abandoning the trailer for a few days?
The reason I ask is that Loch Creran is an SSSI, so has lots of anchoring restrictions so you don't destroy the rare stuff on the sea bed. Just a wee heads up in case you had planned to anchor off your house.
I think the restricted areas might also be noted on the admiralty charts if you have a plotter.
