It's a beautiful area and well worth a visit.
I've paddled round the loch in my sea kayak, camping out one evening here
It's on the North shore about 1.5km past the wee island of Eilean nam Breaban.
There's a few houses north of the woods in this area so you may be able to park somewhere. Probably best to ask someone there if ok to do so.
There's another cracking site with this view about 1km along the shore from Milton Morenish (North West end of loch with boat hire and campsite so parking a possibility)
I know, I know, what's that big bannana doing there, spoiling the shot! (twas my first trip with her
)
Plenty of options for you as others have said, so responsible camping anywhere within the access code is no problem.
Don't know if it's an option for you but there's canoe hire available on the loch. If your not experienced and the weathers good then sticking to the loch shore shouldn't present any problems for you and would make it a trip to remember!
