The best way to protect yourself in Managua, or any big city, is to follow the advice of the locals. Residents will tell you what areas to avoid and why (parts of Barrio Martha Quezada are known to be hangouts for drug dealers and alcoholics, for example). In the city, sections such as the Mercado Oriental are not safe to visit on your own. As the city has expanded, Managua has become increasingly dangerous, particularly for foreigners. Thieves target visitors, who are more likely to be carrying cash, passports and electronics, so be alert for pickpockets and avoid putting yourself in a dangerous situation, such as walking along the streets at night. As always, keep your valuables as inconspicuous as possible and travel with copies of all of your important documents.
