If you haven't spent time in Belize City, you won't understand Belize. Belize City is the commercial, social, sports, and cultural hub of the country. It's even the political hub, despite the fact that the capital, Belmopan, is an hour west. The current prime minister, Dean Barrow, a lawyer who came to power in February 2008, former prime ministers including Said Musa, many of the other ministers, and nearly all of the country's movers and shakers live in or near Belize City.
Belize City is highly photogenic, full of interesting faces, streets full of color, and charming old colonial houses. In short, Belize City has character.
Belize City rewards the intrepid traveler with a surprising number of interesting sights and memorable places, among them the everyday colonial-era buildings in the Fort George and Southern Foreshore sections, where people still live and work. For the most part, buildings are wood, with tin or zinc roofs. Many are in need of a bit of repair, but they still ooze Caribbean port-of-call atmosphere.
As a visitor to Belize, you'll almost certainly have to spend a little time in Belize City, whether you like it or not. The international airport is in Ladyville, at the northern edge of the city. Belize City is the transportation hub of the country, and most flights, buses, and car rentals originate here. If you're arriving late or leaving early, you'll have to overnight in or near the city. Make the best of it. Take care, but explore and enjoy the city.
