Visitors to Colombia need to be aware they face various risks and should maintain a high level of vigilance. The risk of terrorist attacks from domestic Colombian groups in the towns and cities on public places like bars, restaurants and nightclubs frequented by expatriates, is high.While security in Colombia has improved significantly in recent years, violence by narco-terrorist groups continues to affect some rural areas, which can still be extremely dangerous, as well as large cities. In Bogotá, where the threat has decreased in recent years, indiscriminate attacks do still occur. A bomb attack on a video-rental store in the north of Bogotá on 27 January 2009, killed two people and injured at least twenty others. If it is essential that you travel to areas that are remote or reported to be dangerous, you are advised to seek professional security advice and make arrangements for your security throughout your visit. You should seek up-to-date advice from the local authorities before each stage of your journey. The Parque Nacional Tayrona is a popular tourist destination for Colombians and foreigners alike. You are advised only to visit beach areas and resorts you are reliably advised are safe and not to venture inland as illegal armed groups are active and drugs are grown and processed in the area. Common crime also remains a significant problem in many urban and rural areas.
