Lunga is one of the Slate Islands in the Firth of Lorn in Argyll and Bute, Scotland. The "Grey Dog" tidal race, which runs in the sea channel to the south, reaches in full flood. The name "Lunga" is derived from the Old Norse for "isle of the longships', but almost all other place names are Gaelic in origin. The population was never substantial and today the main activity is an adventure centre on the northern headland of Rubha Fiola. The surrounding seas are fished for prawns and scallops and there is a salmon farm off the south eastern shores. The Special Area of Conservation of which the island is part hosts a growing number of outdoor leisure pursuits. Geography Lunga is west of Luing and just north of Scarba. The nearest town is Oban, some to the north. The channel to the south, Bealach a' Choin Ghlais (pass of the grey dog), is only wide and is scoured by the notorious "Grey Dog" tidal race which reaches when in full flood. 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. So great is the overfall on the current, that even during moderate tides it is impossible to force a boat through. This strait is sometimes called the 'Little Corryvreckan' after its greater cousin between Scarba and Jura just a few miles to the south. There are numerous islets in the surrounding waters. To the north is the isle of Belnahua and to the north west are Eilean Dubh Mor and the Garvellachs. Due west there is only Dubh Artach lighthouse between Lunga and the open Atlantic Ocean. At high tide the northern tip of Lunga becomes several separate islets with Rubha Fiola (headland of the tidal island) to the north, then Fiola Meadhonach (middle tidal island), Eilean Ioasal (humble island) and Fiola an Droma (drum-shaped tidal island) closest to Lunga proper. 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. This complexity of land and sea coupled with the strong tides makes these the most treacherous channels on Scotland's west coast. The highest point is Bidean na h-Iolaire (peak of the eagle) and the main bay is Camas a Mhor-Fhir (bay
