Lagg is a very small village on southern coast of the Isle of Arran in Scotland made up of a few houses and a hotel. The family run hotel has a restaurant and is one of the oldest inns on Arran, dating back to 1791. The shop/post office has closed and the hotel no longer has a public bar.
There are various cairns near Lagg on either side of the local river, reached by a forest footpath near the bridge that follows the riverbank south towards the sea.
From Gazetteer of Scotland by Rev. John Wilson in 1882: "It has in vicinity of Lag a post office designated of Arran Island, a parochial church, a Free church, and a public school with about 81 scholars."
