The Belle Vue Hotel has duly identified and accredited some taximen to park in front of the hotel for your service. They are all experienced professionals. They offer reasonable rates and know the geography of the city to perfection. You can pay at the race or rent the taxi on time for a flat fee.
Tip: Do not take a taxi at random if you do not know the city of Lubumbashi. You could inadvertently come across a novice driver, at random rates and who does not know the names of the streets.
