There are four bus companies operating in the country's major cities: Rimbo, SNTV, Maissagé and Air Transport. Buses from Zinder to Niamaey take between 8-10 hours (although this is quite unpredictable) and split about 4:30 am. from the autogarage of Zinder every day (this may change from day to day). Minimum booking one day before. Price is around 12.000 CFA one way. SNTV has a/c bus on Wed-Fri-Sun, price around 16.000 CFA. Anyway, be ready for a long and dusty day!!!
