Hi there, We're on a backpacking trip, traveling by public transport/motorcycle taxis. We're in Noubou, south of Salemata in Senegal, just a stone's throw from the Guinean border. Do you know if it's possible to cross the border in this area? Where do we register? Can we cross the border without an official border post and just register in the first town we come to? We have our visas for Guinea.
