Scotland is beautiful but it is cold. If it's not raining, it's windy and the weather will chill you to the bone if you're not prepared for it. Even if you visit in Summer, don't expect it to be sunny because, Scotland. You'll have to take a large bag with you wherever you go containing a waterproof, umbrella, hat, gloves, sunscreen and some sunglasses. The weather is beyond temperamental so you'll need to be prepared for anything in Scotland. Maybe just take a hip flask with you and let that beautiful whisky warm you up.
