International flights to Belize City tend to go through Houston, Los Angeles or Miami. There are also flights between Belize and Guatemala, as well as other Central American countries. A combined departure tax and dubious 'airport security fee' (total of US$15) are payable by travelers departing by air. There are bus services from Belize City to Chetumal (Mexico) and to Benque Viejo del Carmen and Melchor de Mencos (Guatemala). A token exit tax is payable at Belizean land border-crossing points. You can travel by boat from Punta Gorda in southern Belize to Puerto Barrios and Lívingston (Guatemala), or from Dangriga and Placencia to Puerto Cortés (Honduras).

Belize has few paved roads and no rail network, so it depends heavily on small airplanes for transport. There are domestic airports in Belize City, Caye Caulker, Corozal, Dangriga, Placencia, Punta Gorda and San Pedro. Buses travel fairly regularly on the country's three paved roads (between Corozal and Belize City, between Benque Viejo Del Carmen and Belize City, and between Belmopan and Dangriga). Most other roads are narrow one- or two-lane dirt tracks, often impassable after heavy rains. Cars can be rented in Belize City if you're at least 25 years old. Bicycles and motorbikes can be hired on the Cayes. Fast and frequent motor launches connect Belize City with Caye Chapel, Caye Caulker and Ambergris Caye.
