[3][6] According to an 1845 description: ... about 1 cable broad, and the stream of water during the greater part of ebb and flood rushes along the narrow pass with much violence.

All around are smaller skerries and islets, including Eilean a' Bhealaich (island of the pass), Guirasdeal to the south west and Fladda to the north.

[11] The only other anchorage for passing yachts is at Poll nan Corran (the sickle shaped pool), on the east coast, which has a pebble beach.

[3] Prior to the Pleistocene ice ages Lunga was part of a long peninsula stretching south west parallel to Kintyre.

The Firth of Lorn glacier sliced this peninsula into several islands, including Islay, Jura, Scarba, Lunga, Luing and Seil.

The bedrock of Lunga comprises a mixture of quartzite, limestone and shale called 'Scarba conglomerate' which predominates to the west and in the tidal islands to the north, with schist and mica-schist to the east.

[3] The legend associated with the Bealach a' Choin Ghlais is part of the same story that surrounds the naming of the nearby Gulf of Corryvreckan (English: the speckled cauldron).

Failing to find him on Jura or Scarba he tried to leap across the strait to Lunga, but missed his footing on Eilean a' Bhealaich which sits in the middle of the channel between the two islands.

[3] The island is owned by the family of convicted child sex offender [15] Torquil Johnson-Ferguson[16] who until 2013 ran the Rua Fiola adventure centre which catered for parties of school age children.

[19] The surrounding seas are fished for prawns and scallops and there is a lease for a salmon farm off the south eastern shores of Lunga just north of the Bealach a' Choin Ghlais by the islet Sgeir Mhic an Altair.

[21] This mini-archipelago has no formal status although Lunga is clearly the largest island in the heterogeneous group that lies 'between the Isles of the Sea and the Sound of Luing'.
