The Foreign, Commonwealth & Development Office (FCDO) of the UK has issued a travel advisory for British citizens planning to visit South America, specifically targeting areas near the Ecuador-Colombia border. The advisory warns against all but essential travel within 20 kilometers of the border due to the presence of organized crime associated with drug trafficking. Notable exceptions to this warning include the El Ángel Ecological Reserve, the Rumichaca border crossing, and the Pan-American Highway. The FCDO emphasizes that the security situation can change rapidly in nearby provinces, including Esmeraldas, Carchi, and Sucumbíos, which are known for illegal armed groups and criminal gangs. Travelers are advised to remain vigilant, follow local advice, and pay close attention to warnings from Ecuadorean authorities. It is recommended to travel during daylight hours with a reputable guide and to have an emergency plan in place, as some lodges may be located far from major hospitals. The FCDO's guidance aims to ensure the safety of travelers in a region where risks can escalate quickly.
