Taxis can be a very good way to explore the local area you are staying in - although long distance trips can get expensive. Ask your accommodation, or someone you trust to put you in contact with a reliable driver. Always agree on a price before you get into the taxi. Taxi's normally have green number plates that start with a "D".
Tropic Air (http://www.tropicair.com) and Maya Island Air (http://www.mayaislandair.com) both have multiple flights daily to various towns around the country and to Ambergris Caye and Caye Caulker. They fly out of both of Belize City's airports, but flights from Belize City Airport IATA: TZA are often significantly cheaper than those out of Phillip Goldson International IATA: BZE. Domestic flights are generally pretty reasonable, and thus popular if your time is limited and budget is not. Flights are operated with planes ranging from 8 to 68 seats. Because of the limited capacity, booking in advance is advisable. For bookings from outside Belize, there is only one internet agent, airviva (http://www.airviva.com), who can make bookings, take payment credit/debit cards/Paypal and then send e-tickets. Some hotels do also offer to make the flight reservation on your behalf.
Of course, if you like to make your own itinerary when traveling around Belize, car hire is an option. There are several car hire companies based at the Philip S.W. Goldson Airport BZE, including major international companies e.g. Hertz, Avis, Thrifty as well as local companies e.g. Pancho's, Crystal, AQ's Car Rental. Several companies also have rental offices located in Belize City proper. Car hire will run upwards of $80/day, even during the low season. Be aware that many rental cars in Belize have manual transmissions, although cars with automatic transmissions are not too difficult to come by. The roads are bumpy, so a four wheel drive is recommended, especially if you plan to drive on minor roads.
Driving is on the right-hand side of the road. Drivers can pass slower vehicles on the left, being very careful to check for on-coming traffic before making a pass. Lighting on minor roads is not great so stick to highways or day time driving.
The main highways through Belize are: the Northern Highway, beginning at the Mexican border; the Western Highway, from Belize City to the Guatemala border; and the Hummingbird Highway, which takes you to southern Belize. These highways will take you almost anywhere you need to go and are relatively well-maintained. And although they are not marked well i.e. no mile/kilometer markers or town signs, the road system is relatively simple to navigate and it's easy to know where you are. The Hummingbird Highway is the oldest, and roughest of the paved highways, and you will often experience potholes and stretches of gravel. The newest paved road is the Placencia turn-off, which is smooth and very well-marked all the way to the southernmost tip of the Placencia Peninsula. Always use caution when entering the vicinity of towns and villages, because Belizean roads are notorious for steep speed bumps.
AQ Belize Car Rental is Belize Premier economy Auto Rental company, with free local pick up, with 24 hour roadside assistance.
Several competing buslines operate on the main road in the north-south direction from Punta Gorda to Belmopan and Belize City. There are bus stations in the main towns, or simply stand on the side of the highway and wave at an approaching bus. Most buses have a conductor in addition to the driver, who stands by the door and will come to your seat to collect the fare at some point during the trip. Fares run anywhere from BZ$2-25 depending on distance traveled.
Express buses can save up to an hour and a half depending on the distance of your trip; they do not stop for passengers waiting on the roadside, making only scheduled pick-ups and drop-offs in towns.
Most buses in Belize are retired US school buses Bluebirds, that have been given a slight makeover, a luggage rack installed, and sometimes a new paint job. They generally aren't too crowded, but you may have to stand occasionally.
Children selling snacks and soft drinks often board the buses at stops, and this is an inexpensive way to have a snack if you've exhausted what you've brought along or just want to try some home-made travel foods.
