The Niger River
Stretching all the way from Gambia to Nigeria, the Niger River is 2,600 miles long. The river is so long that it’ll take weeks by boat to travel the whole distance and in some areas, the route turns into an unusual boomerang shape. The river will take you through the Sahara Desert before arriving to the historic city of Timbuktu, some of the best locations to go sightseeing on the river. If you plan to make the journey, make sure you don’t tackle the river during the dry season when portions of the river dry out, making it much harder to travel through. The journey will be well worth the time as you’ll earn bragging rights about being among the few to ever complete the journey.
