Mingulay is an uninhabited island some way south of Barra. There are several in the area, marking the southern end of the Outer Hebrides archipelago.
Like many other islands, it was once inhabited; in this case, well into the last century. Many buildings are still partially standing. I haven't been to this island yet, but am told that the beaches are particularly good. To get there, hang around the harbour at Castlebay on Barra, ask around, and haggle with whichever fisherman expresses an interest in taking you over. Be bold; Barra fishermen have a reputation for driving a hard bargain.
