You don't need to be too concerned about safety, but do follow a few guidelines
When you arrive in Colombia, you will be amazed by the country's beauty and the people's kindness. However, according to some people, when it comes to safety, Colombia does not have the best reputation. It is not only Colombia that is affected, but also other countries on the continent. Nevertheless, you won't have to be concerned about your safety. In fact, the safety situation has greatly improved in recent years, and if you follow the basic safety rules, you will have no problem at all.
In short, you need to be careful and follow the guidelines to have the best experience in this country. For example, you should not carry valuables such as jewelry and cash in plain sight. If you have a valuable camera, consider carrying it in a plain bag and checking your surroundings before using it. In addition, you should carry your bag on the side facing the street when walking on the side of the road. Moreover, don't take (illegal) street taxis. To order taxis, download the Uber or Cabify apps. You should also take a taxi instead of walking around late at night. If you are still unsure, ask the staff at your hotel or your guide for safety advice, they will be the most knowledgeable.
