Thanks for the info guys. I ended up fishing Drunkie as I did not have the time to organise a boat for Achray.
Anyway, after getting a permit, discovered that the forest drive gate was not open until 10am, by the time I got organised it was blistering hot and flat calm
Not the easiest access from the northern side, wading was ok, if nothing else it kept me cool.

a lot of life on the water but I only seen one fish rise. Too hot, I guess, had a few knocks but ended up with nothing. Great value at a fiver

Still, lovely weather, great surroundings and as I write this I am sitting on the bank having a cold beer. ( the wife is driving )
Ah, what to do tomorrow ??
