Isle of SeilEasdale, Isle of Seil, Scotland.
The Isle of Seil takes about half an hour to drive to South of Oban. It is barely an island at all with a bridge that connects to the mainland that is no larger than your average river bridge. It has a fascinating slate mine industry history in that the area used to supply the whole of Britain by sea and it is worth the visit to spend some time at the museum that can be found at the harbourside. Nowadays it is chiefly visited for access to the sea-fari boats that go out to visit the Corrievechan whirlpool, which is much recommended especially if you get on one of the trips that coincide the moon phases with extreme tides.
