Citizens from most European countries, the United States, Canada, Australia and many other countries do not need a formal visa for entering Colombia. Upon arrival in the country, a tourist visa will be given in the form of a stamp in your passport. This stamp allows a stay in Colombia for 90 days. In case you fall deeply in love with the country and you want to stay longer, it is possible to extend your stay with another 90 days.
Please make sure your passport is valid for at least another 6 months at the moment of entrance in Colombia.
Always check the latest Visa status well in advance of your trip.
