One of the smaller islands in the Outer Hebrides Scalpay has been an important fishing and seafaring island for hundreds of years. There are two good harbours and the Eilean Glas lighthouse which was first built in 1788. The island is a popular wildlife spotting and photography site, look out for seals, otter and sea eagles as well as many other sea birds. The bridge was built in 1998 making the crossing to the mainland much faster and easier and helping the islands community which was in decline. The island has been community owned since 2011 and is part of the North Harris Community Trust. There is a community shop/cafe in Buth Scalpaigh which is well worth a visit.
