Either from a boat leaving from Calabar, through the jungle where during the rainy season mud will be piled as high as the car on either side of the road, or the road further northeast. All are feasible. The jungle is fun.

Likely the shortest route for many overland travellers, but like the car smugglers, corruption and shear volumes of people may create hassles in the south. Seldom used border crossings further north would likely avoid this.
