We are booked on the 12 day South Africa Intensive in Feb 2023 and have been looking at walking tours in Maputo that are not ship excursions. They seem to meet and begin at the Cathedral in the city. Does anyone know where Azamara docks in Maputo and how far that would be from the city center? Is it walkable or would we need to take some type of transportation to get there. Thanks for any input!
