Public transport is not recommended for visitors to Kingston due to overcrowding and unsafe conditions aboard the buses. Taxis are a better option. They come in various shapes, sizes and vintages but should bear a red license plate with the letters 'PPV' indicating it is an authorised taxi. Passengers should negotiate a fare before setting off. Driving conditions in Kingston are chaotic. Although it may seem the most convenient option, renting a car and self-driving can be stressful. Renting a car and hiring a driver may be a better bet for those planning excursions out of the city because some of the roads are in bad condition and in some areas it is quite easy to get lost. Having a driver/guide can also be very informative and enriching to your explorations. Downtown Kingston is easily navigable on foot, but walking anywhere at night is not advisable. Walking in touristy areas during the day is a great way to see the city - just be aware of pickpockets in the markets and crowded areas. Many of the popular attractions outside the city provide transport deals, and many visitors to Jamaica choose to use package tours which solves the problem of getting around.
