You will get your Chad visa in Niamey in one day…
Then travel trough Niger overland; From Zinder you must reach remote village of Diffa – there is local bus once a week – on Thu – I was lucky to jump on…
Departure in the dark at 5 am – arrival to Diffa at 4 pm.
Then look for the transport to Nuigimi. If you are lucky to find companions you can rent a 4WD car – write a contract in french. Make sure that petrol is included in the price.
After hard bargaining it was 66 USD for bumpy and sandy 130 km – like 5 hours drive… It is real African Outback!
