Nigeria

Visa: Nearly killed us but got in London before departure. they are apparently available in Bamako. We had 3 months to get the border and made it by the skin of our teeth. 200 USD each!

Insurance: Carte Rose

Diesel: Can be difficult to get. 40 N if you can be bothered to queue for hours/days.. 120 N otherwise, fluctuates a lot. 

Police: A lot of checkpoints, up to 20 a day. When crossing the border from Benin, they didn't wear uniform and tried to throw nails under the car if you didn't stop. No bribes paid. 

Accommodation

We stayed in hotels for 4 nights as we drove across. 

Drill Lodge - Camping for 4000N 7 hours north of Calabar. A real treat of a place.
