Your domestic flights within Ethiopia are operated by Ethiopian Airlines.
Transport in the northern region is provided in a 4WD Toyota V8 or Highroof (depending on the number of passengers). For the Danakil Depression the transport will be in a 4WD Nissan. All car costs like park fees, driver/guide, washing, fuel, etc. are included in the rate of your tour.
Your driver/guide is a professional and experienced English-speaking Ethiopian guide.
All journey times are close approximations, as you can never quite guarantee what will happen on African roads. You could be in for a bumpy ride on parts of the route, you may encounter road work and, of course, there are the photo stops.
While you may sometimes be seated for long periods, you will be passing some spectacular countryside and there will always be something of interest to see along the way!
