In Lima, as in every major city, and other cities within Peru, there are some areas more dangerous than others. Visitors should be alert. Before going anywhere, travelers should check to see if the area is risky to prevent any trouble.
By taking precautionary measures, it is improbable that visitors should run into any trouble. Visitors traveling through a problematic area should not wear jewelry.
Valuable items are best left at one's lodgings. Do not carry flashy handbags or briefcases. Do not carry large amounts of cash, and if taking along a film or photographic camera, ensure it is kept hidden most of the time.
