The Wikipedia entry on Machair has not one, but two, images of Berneray. So this is a place to visit to experience the phenomenon. A walk around the island gives contact with the sea, shore, dunes and this fertile, luxuriant-looking pasture which features on some of the West Coast of the Mainland and certain of the Western Isles. Pick the right time of year and the colours as well as the impact made will be memorable.
