Just did an amazing trip from Inverness to Fortwilliam via Spean Bridge and the summit of Nevis.
Two of us in a Canadian Canoe non stop from Inverness. We started at 4am and staggered to the summit of Nevis having left our canoe on the shore in Fortwilliam. It took us 30hrs and 23 minutes from start to finish. Would post some photos but the camera is keeping Nessie company at the bottom of Loch Ness(Doh)!
This is a great trip for those who want to test their endurance. Found the route on a Blog by some guys that post routes they have done. No cost involved other than getting there and doing your thing.
The route is detailed on the blog at http://beastthegreatglen.wordpress.com/
