Vanuatu's undeveloped road system, with fewer than 100 miles of paved roads, consists mostly of dirt tracks suitable only for four-wheel-drive vehicles. Every island has one or two short airstrips where Vanair’s Twin Otter planes land two or three times weekly. In addition, every island has a small port or wharf where small cargo ships and boats regularly dock. After arrival on an island, transportation is usually via pickup truck, foot, or small boat. Bicycles are becoming popular in Vanuatu. Port Vila and Luganville have numerous taxis and mass-transit vans. There are no railways in Vanuatu, although there was a small rail line on Efate during the colonial era. Vanuatu's main harbors are Forari, Port-Vila, Santo (Espiritu Santo).
