I’m just back from a coast to coast trip (west to east) Starting near Oban and finishing at Spey Bay. Similar to one that a couple of others on here did in that it followed the Spey for the last section. But a different route from the start, also including Rannoch Moor and Loch Ericht. It could have been better. I’d planned a lot of peaks along the way but with mostly crappy weather was uninspired to go high in the end. More summits could have made it a really great trip but it was still fun. I put a report on my blog:
Cheers, Dave
