Getting around Lusaka is not easy. While the city centre is relatively small, walking is not always a pleasant experience because of the climate and the hawkers along the sides of the roads. Public transport consists of buses and minibuses that run frequently along main transport routes, helping people get around the city. However, buses and minibuses can get crowded, meaning they're not always a comfortable way to travel. Visitors who have an international driving licence can hire a car, and there are plenty of reputable car hire companies in the city and at the airport. On the downside, driving in Lusaka is not an easy task because traffic is often gridlocked and it can be difficult to find parking. While signage is usually quite clear, the condition of the roads is not always good. Hiring a car with a driver is a popular option.
