Overall, Scotland is a very safe country to travel in, but be a cautious traveler and keep your cash, passport, credit cards, and tickets close to you or in a hotel safe. Don't agree to carry anything for strangers. It's a good idea to distribute your cash, credit cards, IDs, and other valuables between a deep front pocket, an inside jacket or vest pocket, and a hidden money pouch. Don't reach for the money pouch once you're in public. Use common sense as your guide.
