There are no internal domestic flights in Burundi.
Minibus & Shared Taxi
Travelling around the countryside is not as dangerous as it once was, though things change quickly (for better or for worse) in this part of the world.
As in Rwanda, most major roads in Burundi are sealed. Public transport mostly consists of modern Japanese minibuses, which are cheaper than shared taxis and not overcrowded. Destinations are displayed in the front window, and minibuses depart when full. You can usually find a minibus or shared taxi heading in your direction any day between early morning and early afternoon at the gare routière (bus station) in any town.
