Finnart / A-Frames

Wreckage of an old dynamited pier on a gentle reef slope

Finnart, also called the A-Frames, is a Loch Long shore dive at the oil terminal the Americans built during the Second World War. A gentle reef slope carries the wreckage of the old pier, with no current to fight. It is a standard training site that also lets deeper divers head out into the loch.

Also known as Finnart, A-Frames, The A Frames, Finnart Oil Terminal.

The dive

Divers walk down the cleared path to the beach and swim straight out onto a gentle slope with no current. Wreckage from the dynamited pier lies at around 8 to 12 m, and a whole dive can be spent zig-zagging this debris field among squat lobsters, edible crabs and velvet swimming crabs. Below 20 m stand the A-Frames, the remains of the old pier that give the site its name, covered in anemones, starfish and dead man's fingers. Divers who want more depth can carry on out into the loch, where getting past 40 m is easy and fireworks anemones have been seen.

Season follows Loch Fyne & Loch Long: Diving runs all year with no standout month; long spells of rain leave the water dark and murky, and settled weather clears it.

Know before you go

  • Fast cars and motorbikes use the A814 beside the site, so kitting up and crossing need care.
  • Silt cuts the visibility when the site is busy or a ship has just come in.
