The island of Mousa boasts the most amazingly well-preserved broch in Scotland. Rising to more than 40ft, and looking rather like a Stone Age cooling tower, Mousa Broch has a remarkable presence, and even makes an appearance in the Norse sagas. The low entrance-passage leads through two concentric walls to a central courtyard, divided into separate beehive chambers. Between the walls, a rough (very dark) staircase leads to the top parapet; a torch is provided for visitors. Mousa is only a mile wide, but if the weather’s not too bad it’s easy enough to spend the whole day here. From late May to late July, thousands of storm petrels breed in and around the broch walls, fishing out at sea during the day, and returning to the nests after dark.
A small passenger ferry runs to Mousa from Sandwick. The ferry runs special late-night trips, setting off in the “simmer dim” twilight around 11pm.
