Main image

Belnahua is a small, uninhabited island in the Slate Islands group off the west coast of Scotland, known for its historic slate quarries.

Commercial slate extraction took place on Belnahua during the 18th and 19th centuries; operations declined and the island was later abandoned, leaving the quarry structures and landscape scars as evidence of its industrial period.

Belnahua lies in the Firth of Lorn among the Slate Islands off Argyll on Scotland’s west coast, between larger islands in the archipelago.

  • Quarry remains: Formerly the site of active slate quarrying, the island retains ruined quarry buildings, piers and industrial archaeology dating to the 18th and 19th centuries.

Tips for Visiting Belnahua #

  • There are no visitor facilities; if landing by boat, check tide tables and plan for strong currents between islands.
