Loch an Eilein Castle Walk
Aviemore, Highland
Loch an Eilein is a jewel of the Cairngorms, a pine-fringed loch with a ruined 13th-century castle on a small island. The circuit walk through ancient Caledonian pine forest is one of the most beautiful in Scotland and a favourite with dog walkers year-round.
The Route
Start from the Loch an Eilein car park and follow the well-maintained path clockwise around the loch. The route passes through towering Scots pine and birch woodland, with the castle island visible across the water. The southern section is quieter, with the path hugging the shore through ancient forest. Red squirrels, crested tits and crossbills are regularly seen. Optional extension to Loch Gamhna adds another mile through deeper forest.
Dog-Friendly Details
Dogs can be off-lead throughout the walk. The forest floor is soft pine needles and the paths are wide and well-maintained. The loch provides multiple swimming access points. Keep dogs under control near the shore if ospreys are fishing (summer months). This is one of Scotland's most dog-friendly walks.
Practical Information
Rothiemurchus Estate car park (charge applies). No cafe at the loch. The visitor centre at Rothiemurchus has refreshments. Toilets at the car park. The path is suitable for pushchairs. Best in autumn when the birch trees turn gold.
