Most visits to Panama are trouble-free. Visitors should, however, be aware that there is a risk of street crime in Panama City and it is unwise to carry large sums of cash or valuables in public. Visitors should be vigilant using ATM cash machines in public places and beware of pickpockets and muggers in the main city shopping and tourist areas. There have been incidents of assault involving taxi drivers and armed hold-ups in restaurants. Use only registered taxi companies and phone for a cab rather than hailing one in the street. Do not allow the taxi to pick up additional passengers and do not share a taxi with unknown passengers. Burglaries have recently been committed by organised gangs who use ruses to gain entry to properties, so be cautious. Avoid political demonstrations in Panama City, usually centred on Panama University and the main road known as the Transisthmica.
