In which: my guidebook is a massive liar

Today we were meant to go on a boat trip to see dolphins and whales but it had mechanical difficulties and was cancelled.
We got a guidebook on walks and decided to do a 2 hour walk along the beach of Loch Broom in Ullapool to Rhue lighthouse.
5 hours, cliffs clambering and having to cross a mountain that the guidebook omitted to mention, we finished. 15km, not 10km, but very beautiful.
