Start your third day with a visit to the iconic fortress of Eilean Donan Castle which lies at the meeting place of the three great sea lochs, Alsh, Duich and Long. Originally a stronghold of the Mackenzies, the Mathesons were occasionally granted the honour of being constables of the castle. It is now owned by the Macraes and is open to the public.
From here, head west to the Kyle of Lochalsh, from which point you can travel over the bridge to the Isle of Skye. In the south of the island, visit the Armadale Castle Gardens and Museum of the Isles at Clan Donald Skye, which gives a fascinating account of Highland clan history, and is where you can uncover the Matheson’s turbulent connections to Donald, Lord of the Isles.
