Wild Swimming

Loch an Eilein

Loch an Eilein ("loch of the island") is one of the most photographed lochs in the Cairngorms — a mirror-flat woodland loch with a ruined 14th-century castle on a small island. The water is peaty-golden, cold, and crystal clear, ringed by ancient Caledonian pines. Swimming here feels like stepping into a Scottish fairy tale. Entry is from the gravel shore near the car park end of the loch; a 5km path circles the whole loch through old-growth forest.
