About this place

Beautiful Hebridean archipelago with significant seabird colonies

  • Explore a paradise for nature lovers, with spectacular numbers of seabirds and wildflowers.
  • Discover a fascinating human history, from the Iron Age until 1857 when the final residents left.
  • Enjoy an exhilarating journey to the archipelago, with the chance of seeing whales, dolphins and sea eagles on the way.

The Treshnish Isles are a group of eight uninhabited islands and many more skerries, located in the Inner Hebrides to the west of Mull. The largest island is Lunga; the others are Bac Beag, Cairn na Burg Beag, Bac Mor, Sgeir an Eirionnaich, Sgeir an Fheoir, Fladda and Cairn na Burgh Mor.

The entire archipelago is a Site of Special Scientific Interest, and the islands are known for their distinctive silhouette in the seascape – especially Bac Mor (or the Dutchman’s Cap).

In summer many of the islands are covered in rich grasslands and abundant wildflowers. They are also internationally significant as a nesting site for many seabird species including guillemots, razorbills, puffins, kittiwakes, fulmars, shags and skuas. Archaeological sites provide a glimpse of human lives lived there in centuries gone by.

The marine environment surrounding the islands is part of the Sea of the Hebrides Marine Protected Area due to the presence of basking sharks and minke whales. Bottlenose and common dolphins, as well as grey seals, are also found there.
