Last August we went to the North Ledaig Caravan Club Site it is a members only site but is excellent, you are on the edge of a bay with shingle beach, the view accross the bay is of the isle of Mull and you are about 15 minutes from Oban where you can get the ferry to the island. There are several other caravan sites in the area, my brother stayed at a site in Connel which again was excellent. There is plenty to do swimming at oban, the seal rescue centre on the road to fort williams, sea fish, hill walk and of course the Isle of Mull. We will definitly be going again this year, spent a week there and still didn't see everything.
