To the south-west of Tarbet is the small island of Scalpay (covering just 2.5 sq. miles or 653 ha).   It sits just 300m (about 1000 ft) off the coast of Harris and a ferry service operated until 1997 when a bridge was finally built.  At the far wesern tip, is Eilean Glas lighthouse, which was the first lighthouse to be built in the Outer Hebrides (and first illuminated in October 1789).

After parking in Scalpay village, Judith and I walked (6 miles / 9.5 k) along the waymarked circular path which runs around the island.  Though it is possible to drive and park within about a mile or 1500m of the lighthouse.
