Yup, I liked The Slate Isles.
Do Eat at the Tigh Na Truach, just over the Bridge, they give you HUGE servings
Its £1.60 each way (no return) to Easdale, and I think the same if your on Foot to Luing.
The shellfish on Ardinmar beach, East Coast of Luing are huge!
A few plantations, but Id reccomend a Bivvy, as few trees and the grounds too hard for tent pegs.
Campings limited but remember me to the Guy in Kilbride Farm, Seil island, you can stay there.
I stayed three nights.
The main economys Lobsters, but I did not see any. (never looked, you may be able to pick one up cheap)
The highland arts centre do great ice cream, look out for the lioness skin hung from the celing. (Dont camp in their car park; £8 a night for no facilities)
