Getting to know the Treshnish Isles

Stretching over seven kilometres, the Treshnish Isles are one of the biggest draws on the West Coast of Scotland.

The small Archipelago is formed by a series of small islands and skerries (a reef or rocky island), and is part of the Inner Hebrides chain of islands.


Owned by the Hebridean trust, the islands were once inhabited by people, the last of whom left the isles around the mid-19th century. The heritage of these settlements can still be found through remains of centuries-old buildings, including a church on Lunga, the largest of the islands. Lunga is also where our tour boats stop at the Treshnish Isles.

The isles also once formed part of the historic 'Kingdom of the Isles', a Viking and Middle Ages island empire that spanned from the Isle of Lewis in the north to the Isle of Mann in the south. The isles have changed hands many times since, before eventually being abandoned by Donald Campbell and his family in 1824.

Today, the islands' main residents are Puffins and other sea birds. Only three miles from the Isle of Staffa, the Treshnish Isles form a rich part of the wide and compex ecosystem across the whole West Coast.

As with the Puffins on Staffa, Treshnish Puffins are incredibly friendly. They'll come up close and even pose for photos!

There are approximately 47 other species of birds on the island, including:

  • Razorbills
  • Guillemots
  • Fulmars
  • Storm
  • Petrels
  • Kittiwakes
  • Herring Gulls, and
  • Shags

The islands also boast a variety of sea and land animals, including otters and seals, whales, dolphins, basking sharks and sea eagles.

Along with visting Staffa, our daily boat tours take our guests to the Treshnish Isles to discover some of Scotland's most historic and beautiful islands first hand.
