 Lochs Bracadale and Harport and the island of Wiay lie between Duirinish and Minginish, which includes the narrower defiles of Talisker and Glen Brittle and whose beaches are formed from black basaltic sands.Strathaird is a relatively small peninsula close to the Cuillin hills with only a few crofting communities, the island of Soay lies offshore.The bedrock of Sleat in the south is Torridonian sandstone, which produces poor soils and boggy ground, although its lower elevations and relatively sheltered eastern shores enable a lush growth of hedgerows and crops.
