@kuriosiesouschristos For another beautiful Scottish walk, I can highly recommend the Great Glen Way. I did the Fort Augustus to Inverness section (i.e. along Loch Ness) over 3 days with friends. I think it was about 50 miles total, with a lot of elevation changes (some gradual and some not so gradual, but all totally doable for reasonably fit novice walkers). Really stunning.
