Bac Mòr is a Scottish island, one of the Treshnish Isles,[3] sometimes referred to as The Dutchman's Cap in English due to its shape.[2]

Origin of name[edit]

The Gaelic name has more than one possible interpretation. Mòr means large (as opposed to Bac Beag, its smaller sister), but Bac can mean a "bank", or also an "obstacle" or "hindrance". The island's profile is one of the more distinctive amongst the Scottish Islands.


Bac Mòr from Lunga

Bac Mòr is of ancient volcanic origin, and the peak in the middle is a former cone. The low lying plain surrounding it is formed from a glassy lava field.

Despite having no safe landing places, there are the remains of summer sheilings on the island.


The Treshnish Isles are uninhabited and are owned by a charity, The Hebridean Trust. They are designated a Site of Special Scientific Interest and a Special Protection Area due to their importance for breeding seabirds. There are also a number of wildflowers there.
