The Treshnish Isles is an archipelago of small islands and skerries, lying west of the Isle of Mull, in Scotland. They are part of the Inner Hebrides. Trips to the Treshnish Isles operate from Tobermory and Ardnamurchan in the summer months.
The archipelago stretches for roughly 7 kilometres (4 mi) from the island of Bac Beag in the south towards Cairn na Burgh Beag to the north east. The largest island in the group is Lunga, which is 7 kilometres (4 mi) west of Gometra, 6 kilometres (4 mi) southwest of Rubha' a' Chaoil on Mull, 12 kilometres (7 mi) south east of Coll, and 5 kilometres (3 mi) north west of Staffa.

There are several possible duns on the islands of Iron Age origin. Little is known of the early history, although these prominent landmarks would have been significant waypoints for the Norse settlers during their conquest in the early years of the Kingdom of the Isles, which lasted from the 9th to the 13th centuries. There are remains on Lunga of a village of blackhouses abandoned in 1857
The Isles were purchased in 1938 by explorer and naturalist Col. Niall Rankin and they were sold to the Hebridean Trust in 2000. The Trust are guardians of the islands to protect them and the wildlife and to monitor and study the ecology and archaeology.
Due to the beauty and remoteness of the Isles and the abundance of wildlife, particularly the puffins, they are very popular with tourists who visit by boat, generally to Lunga, for day-trips during the Summer.
Bac Mòr is also known as "The Dutchman's Cap" in English due to its shape. Bac Beag is from the Gaelic Am Baca Beag, with Bac meaning "bank" or "dune" and Beag simply being a diminutive in contrast to Mòr. Bac Mòr is also known as Baca Rois in Gaelic, which means "dune of the Ross" and is a reference to the shape of the island when framed against the Ross of Mull. Lunga is probably from the Old Norse lungr-øy, meaning "longship island". Sgeir an Eirionnaich and Sgeir a' Chaisteil are Gaelic names meaning "Irishman's skerry" and "castle skerry" respectively. Cairn na Burgh Mòr means "cairn of the large fort" and Cairn na Burgh Beg is thus "cairn of the small fort".
The name Fladda originates from the Old Norse for "flat island".
Natural history and conservation
The Treshnish Isles are part of the Loch Na Keal National Scenic Area, one of 40 in Scotland. They are also designated as a Site of Special Scientific Interest, a Special Protection Area due to their importance for breeding seabirds and a marine Special Area of Conservation. They are also known for their Atlantic grey seals and ruined castles.
