Absolutely worth going!
There is no secret about Scotland being one of the most beautiful places on Earth. Edinburgh is a charming, delightful, medieval city. Mixing the old with the new, Edinburgh is like no other place you have seen it! Scottish people are very welcoming and friendly, you will feel at home right away. Good transportation, you have easy access to buses and trains running all day to the Highlands and cities nearby, like Glasgow for example. It's a must in anyone's bucket list.
Insider Tip:The Highlands Day Tour leaving from Royal Mile and National Museum of Scotland is a must. Also if you make it to the Fringe Festival you won't regret it!
