I have various proposals for March 2015 and would welcome your view.
1. We could stay at Slochd Bunkhouse just off the A9 after Aviemore - Very comfortable, luxurious even and is £20 per night. This opens up Cairngorms and further North. They also have Nordic Skis for hire should there be adequate snow.
2. Culdees Bunkhouse , Aberfeldy. £18 a night and is a little closer - Loch Tay.
3. SMC hut below Buchaille Etive Mor £10 per night
All have pros and cons - Let me know your preferred option and also dates in March. It will be subject to hut availability!
