The airport of the city is the Moi International Airport. Mombasa has a railway station and Kenya Railways runs overnight passenger trains from Mombasa to Nairobi, though the service is less extensive than it used to be. Highways connect Mombasa to capital Nairobi, former Tanzanian capital Dar es Salaam while northward road link to Malindi and Lamu. Within Mombasa, most local people use Matatus (minibuses) to move between villages and Mombasa Island. Mombasa port is the largest in Kenya but there is little or no scheduled passenger service. International cruise ships frequent the port, thus giving Mombasa a "Natural Harbour." There is no bridge between Mombasa Island and south coast, instead the distance is served by ferries from Kilindini and Mtongwe to Likoni in south coast. Operating ferries are aged. In 1994, a ferry serving Mtongwe route sank, leaving 270+ people perished.[7]
