I'm really not sure if Loch Creran is worth the effort, unless you are desperate for a very classy meal at the Isle of Eriska Hotel. Somehow it is a rather dull loch for visiting boaties, albeit with nice mountains at the far end (but guarded by the road bridge) heading up towards Glencoe, and lovely woods too. The roads down each side are obtrusive, and so are the houses. It is generally too populated for my taste. Anyway, anchoring in the loch is very restricted because it is now a Marine Special Area of Conservation. There are bedrock and biogenic reefs, the latter made from the tube-worm Serpula vermicularis (known as serpulid reefs, apparently the largest in the world) and the horse mussel Modiolus modiolus (known as horse mussel beds) which can be all too easily damaged by anchors. Maybe boaties should leave the place to the worms and visit by road, especially as the serpulid reefs appear to be dying — for reasons unknown.
