Loch Arail (sometimes listed as Loch Ellen[1]) is a remote loch in Argyll, Scotland, situated on the side of the B8024 road roughly 2.8km northwest of the settlement of Achahoish.
OS maps from the late 19th century record the loch's name as "Errol".[2] It is unclear whether the loch's toponymy is related to the village of Errol, in Perthshire.
The loch has a stock of brown trout suitable for fishing.[3]
Loch Arail sits on a bedrock of quartzite and pelite. A large peat bog known as Moine an t-Saraiche sits on its southern shore.[4]
