The Treshnish Isles are formed from 8 principal islands varying in size, with Lunga being the largest island in the archipelago.
Located at its closest 3km west of Mull, the Treshnish Isles archipelago extends along a northeast-southwest for a distance of 11km. The most accessible island for visitors is Lunga.
Apart from the scenery of the Isles, their mystique as a group of uninhabited islands holds nationally important treasures in the form of a medieval castle as well as a thriving community of wildlife.
Inhabited by huge colonies of seabirds, the islands have attracted travellers and visitors for at least 1000 years and some place names are rooted in the Viking language, reflecting their Hebridean rule.
