To travel to the Isle of South Uist there are two options, by ferry and by plane.
There is a causeway from Berneray to North Uist in the north, and a series of causeways linking North Uist to Benbecula, South Uist and Eriskay to the south.
The ferry to and from the mainland departs from Oban in Argyll and goes to Lochboisdale, either directly, or via Castlebay in Barra.
