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. The highest point is
Bidean na h-Iolaire (peak of the eagle) and the main bay is
Camas a Mhor-Fhir (bay of the giant) to the south which provides an escape route from the Grey Dog. 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. ==Geology==
