Why bypass Nigeria?
Drove Amsterdam-Capetown through WestAfrica and then Ghana/Togo/Benin/Nigeria into Cameroun.
The coastal border is very streamlined and altough they ask for a gift its not persistend. The roadblocks is something to get used to, but they stop you mostly to have a chat....
You will need to stay in Lagos for the Cameroun visa (or go to Calabar in the unstable delta region). We stayed in the Yaba district, it was quite an experience. Never seen such a hetic, energetic, bustling city. Ended up staying for a week or so.
Petrol situation is quite difficult, but mostly when you jump the queue (you gotta) and tell them you drove all the way from .... on this machine etc etc blablabla you will be served. They have a good sense of humor.
From Lagos we drove NorthEast into Cameroun, bypassing Abuja. The north is very different from the South, respectful moslim mainly and you are mostly being left alone.
You also gotta stop in Wikki Warm springs, very cheap national park were you can camp and relax in the hotspring..
Talk to people who've been through (www.tifua.com
) and there are all positive. All the other (negative stuff) is mostly hearsay...
