Good brown trout places around Inverness
 

I have a friend who's a beginner and I'm looking for a nice loch where
he's got a good chance of catching something. The closer to Inverness
the better as I don't have a car and have to rely on buses/train/bike.
I don't mind waling up to hill lochs.

Basically, I just want a suggestion of a good loch near Inverness
that's good for beginners.
