At the northern end of the island is this lighthouse, over 100ft high and one of many built across Scotland by the Stevenson family. A visitor center and licensed cafe are here, as are bikes for hire and a gift shop selling the woolens made from yarn supplied by the local seaweed-eating sheep. You can climb the lighthouse itself and/or visit the woolen mill on a tour.
On the shore to the south of the lighthouse is an earlier model, an 18th-century beacon tower some 70ft high.
