Andorra is a UN Member State, located high in the Pyrenees, sandwiched between Spain and France. There is neither an airport nor a railway so unless you have a car, or want to walk, bus is the only way. DirectBus run 8 services a day from the airport in Barcelona, stopping at Barcelona Sants, to Andorra La Vella.
Am not a big fan of Tanzania. It's my second visit here. I was really just passing through. After just 5 days/4 nights I crossed the border at Tunduma to Nakonde, Zambia
In 2020 I was in West Africa. this is my report as I travelled from Mali to Côte d'Ivoire, Sikasso to Ferkessédougou at the Zegoua/Pogo border crossing
