The Treshnish Isles form an archipelago to the west of Mull.
Whilst the islands are uninhabited today and owned and looked after by the Hebridean Trust, the islands have provided both a home and a place of refuge for humans at various points during history. The most recently-occupied settlement is a small village on the isle of Lunga, which was abandoned in the mid-19th century. There are ruined castles and evidence of early settlements on a number of the other islands.
The main islands are Lunga (the largest and the nesting site of thousands of puffins and other seabirds during the summer months), Fladda (the northernmost island with a distinctive flat top), Bac Mor (known as the 'Dutchman's cap' due to its distinctive shape with a peak in the middle) and its smaller sister Bac Beag, Cairn na Burgh Mor and Cairn na Burgh Beag (relatively flat-topped with steep cliffs), Sgeir a' Chaisteil and Sgeir an Eirionnaich. In addition to these islands, there is a large collection of smaller skerries.
The islands are now protected as part of the Loch Na Keal Scenic Area and are also protected due to their significance for seabirds and marine life.
The Treshnish Isles can be reached by boat from Mull or Iona - we recommend a day trip with Staffa Tours during the summer months to see the puffins on Lunga.
