Achnacarry (Scottish Gaelic: Achadh na Cairidh) is a hamlet, private estate, and a castle in the Lochaber region of the Highlands, Scotland.

[1] Between Achnacarry Castle and Loch Arkaig is a path of interwoven trees known as The Dark Mile, or Mìle Dorcha in Gaelic.

One of the few remaining descriptions relates that Lochiel's seat was "a large house, all built of fir planks, the handsomest of that kind in Britain."

Sir Ewen's bard described the home somewhere around 1663 in song as "The generous house of feasting...Pillared hall of princes...Where wine goes round freely in gleaming glasses...Music resounding under its rafters."

[3] In 1665 the Stand-off at the Fords of Arkaig took place near Achnacarry, which saw the Camerons finally end their 360-year feud with the Chattan Confederation led by the Clan Mackintosh.

Donald was planting a long line of beech trees near the banks of the River Arkaig when word of "Bonnie Prince Charlie's" landing arrived in 1745...it would be the last landscaping done at Achnacarry Castle for years to come.

[3] With the Jacobite army's defeat at the Battle of Culloden in April 1746, the clans retreated into the Scottish Highlands, with Donald taking the lead in regrouping them.

Generally, it is a timed 7 mi (11 km) march, in full battle gear, backpack and combat boots, from Spean Bridge (site of the striking Commando Memorial) to Achnacarry.

Other exhibits include artefacts associated with the castle and estate's history, with the Queen's Own Cameron Highlanders, and with "Bonnie Prince Charlie".
