Visas
Nigerian visas need to be bought in advance. We got our 30-day tourist visas at the Nigerian embassy in Yaounde (Rue Joseph Mballa Elounden in Bastos), which took our passports late Friday and handed them back Monday morning. The application was straight-forward but they weren't cheap - the cost for Brits is 62,000 CFA each (roughly £70). The visas cost the same whether you state you want transit or tourist, the only difference being the number of days you are given at the border itself.

Border formalities and checkpoints
The border at Boukoula was very quiet and free of complications. Immigration were helpful and friendly whilst customs just wanted our details and were totally disinterested in our car. Be careful that they fill in your carnet de passage correctly as they seemed unfamiliar with the document. Exiting the country at Kongolam was similarly laid-back.

There was a police-check immediately after the border but they just wanted to copy our details down and were very friendly. We were waved through every other checkpoint bar one, but he just wanted to talk to us about the football! We didn't have third-party insurance for Nigeria but had no problems as we were never asked to present documents.

General driving conditions
The main highways have some potholes but are generally good tar roads. Most of the lesser routes are poorly maintained and terribly potholed. As well as the usual taxis and buses there are many giant coaches and fast saloon cars on the road. Most drivers are aggressive and incompetent.

Specific driving conditions

• Boukoula to Mubi - 1 hour on 4x4 dirt track.
• Mubi to Hong - 1 hour on good tar.
• Hong to Little Gombi - 1 hour on good tar.
• Little Gombi to Biu - 1 hour on partially potholed tar.
• Biu to Dindima (turning for Yankari) - 4 hours. Bad potholes to Wuyo but better after.
• Dindima to Yankari gate - 1.5 hours on new perfect tar.
• Dindima to Jos - 4 hours. Good tar with some potholes.
• Jos to Zaria - 4 hours. Good tar with some sneaky potholes. Armed police block (easily distracted)
• Zaria to Kaduna (Abudja to Kano Expressway) - 45 mins. Good tar, two lanes and occasional pothole.
• Kaduna to Kano (Abudja to Kano Expressway) - 4 hours. Good tar, two lanes and occasional pothole.
• Kano to Kongolam - 2.5 hours good tar. Some customs/immigration roadblocks but we had no problems.

Accommodation
Camping is available in the interior of Nigeria (we stayed in the grounds of guest houses and hotels) but we didn't bushcamp. In some towns we stayed in cheap rooms.

• Biu – Tourist Lodge (N10.37.107; E12.10.386). Tatty, but acceptable late in the day, and a basic room was only 800N.
• Yankari National Park - they say they offer camping but then make you camp in the tarred car-park and use the toilets by reception (no shower). We eventually complained so they opened the toilets and showers for the (unused) squash courts which were brand new.
• Jos - COCIN guest house (Noad Avenue). Friendly and very central. A large room was only 1000N.
• Zaria - New Zaria Motel. We convinced them to let us camp in the spacious hotel grounds for 1000N. Ablution facilities not ideal: we used the reception toilets and they opened a room every morning to let us shower.
• Kano - Tourist Camp. Camping in the back car park of the tourist camp for 500N each. Good central location but ablution blocks are dirty and well-used.

Food, water and beer
Nigerian food is very tasty with spicy meat, chicken and offal sauces and several types of carbs laced with palm oil. You can eat in Chop Bars for as little as 250N or upgrade to fast food outlets with aircon, including the high street favourite Mr Biggs (500N). Foreign restaurants in Kano are a more expensive but well worth it, especially the delicious and generous Spice Inn on Magasin Rumfa Road (Indian buffet on a Sunday for 1200N).

The Oasis Bakeries (in all major cities) do good but expensive wheat bread (400N a loaf). The Lebanese supermarkets opposite the Tourist Camp in Kano have loads of imported goods but at ridiculous prices.

Fruit and veg are not abundant although we found many good mangos, bananas and enormous grapefruits, as well as tomatoes, peppers, carrots and peanuts in a bottle.

Water shortages are as commonplace as power-cuts in Nigeria. Many places supplied us with plastic buckets of well water which made it difficult to take water for drinking. Bagged 'pure water' is very cheap (70N for 24x50cl bags). Nigerians think the harmattan makes it freezing cold so they will all supply hot water in the morning if you ask!

We mostly drank Star lager (170N in drinking spots, 300N in top hotels in Sharia Law territory) but after a while we switched to Heineken and felt better in the morning. Gulder also widely available.

Money and fuel
The ATMs in Nigeria do not accept foreign cards but there are plenty of foreign exchange bureaux, especially in expensive hotel complexes. We changed US$ at the souvenir stalls outside the Zaria Hotel and at the Hamdala Hotel in Kaduna. The Kano Tourist Camp has its own bureau which has good rates for both Euros and US$.

New Naira notes were issued in 2007 and, although they were still valid when we were there, some places were funny about taking the old 50N note in particular (check the posters when you change money).

Diesel is more expensive in Nigeria than petrol and costs 110N (49p) per litre. Fuel stations line the highways, most of them seem closed whilst others are open but with no customers. Drive around until you find a busy one (a sign of clean fuel) and confirm the price before they start as the price displayed on the pump is often not what they charge.
