As a native Scot I have used this book frequently to the extent that it is now falling to pieces! Not only are the recommendations for hotels, restaurants, walks, beaches, historical places, waterfalls etc etc consistently good, they are well laid out and easy to access. I use this book as a guide when I want (eg)a restaurant to eat in, but I also love to peruse it as a reading book, inspiring me to visit new places and take detours off my regular routes.
I would highly recommend this book to locals and tourists alike. Buy it well in advance and use it to plan your visits. If you are a foody you'll get hungry reading the descriptions of restaurants and if you've never been here before the 'tick' rating system will help you decide upon the best things to do.
