The Gambia
The Gambia is a small country in Western Africa.
Hitchhiking
Hitching is common in The Gambia and especially near the relatively developed western region locals hitch regularly. The two main highways along the south and north bank of the river see lots of traffic with a high proportion of personal vehicles. Getting rides with the police or military is also relatively easy.
The number of vehicles significantly decreases as one travels upcountry to the east, but the occasional truck, motorcycle, or NGO vehicle will offer a lift, especially if you are walking along the side of the road in the bush.
Traversing the country to travel between northern Senegal and Casamance is not too difficult because many truckers and Senegalese with personal vehicles make the journey, although expect to wait a long time to cross the river.
