4WD cars are the best to drive in Senegal. West African roads are not in good shape. Roads in Senegal are BAD on the way from the Border Rosso north, to Saint Louis, you have +-100km of roads full of craters. The road heading North aside the Senegal River all the way to Ouro Sogui and Matam is in really bad shape, better to go off the road than actually going on the few asphalt left on the track. After Ouro Sogui near Matam and going all the way to Kidira and Tambacounda the road is very ok, no problem with this one. Going south o Niokolo Koba (except on the Park itself where you need a 4wd to make many trajects) is ok. The road to Velingara from Tambacounda is ok. From Velingara to the border with Gambia no road just tracks full of holes and red sand and dirt.
From the gambian border to kaolack road is not good, expect many hours to make just a few kms. From Kaolack to Thies is ok and then to Dakar is good. Dakar to Saint Louis is more or less ok.
On the picture you have a broken road between Matam and Kidira that was taken by the strong waters of the recent rains.
