I look forward very much to reading this in full later, but after a quick glimpse, I gotta say I disagree about the Uists! We thought they were gorgeous! It rained harder than I'd ever known rain previously, and the wind blew a hoolie, but through brief moments of sunshine, we thought the scenery was fabulous... Mind you - we live in Southampton so it's all relative. ;) We only spent 3 days there but I'd happily do a fortnight.
Totally agree about Harris though. Awe inspiring scenery... Another place I need to spend more time in. Beautiful island... I do love Lewis as well - as you say it's so sprawling (3rd largest of the British Isles!) and because of that the scenery is so varied. Great Bernera is amazing... Probably the place on Lewis I've spent the most overall time at.
Good to have you back! :)
