Entering Belize from Mexico is easy, even on a bus. Stop at the office on the Mexican side, have your passport stamped and hand in your Tourist Card. On the Belize side, stop in the office and fill out a form of intent and a customs declaration. If you're driving, be sure to declare your car because they stamp your passport with an additional receipt. Rental cars are not supposed to be taken in, but if you do, be sure to buy Belizian car insurance just over the border.
Money changers conveniently wait outside the border office. You can spend US dollars if you don't want to bother exchanging, especially if you are only going in for a short trip. The exchange rate was BZ$ 1 = US $2.

In the middle of the peninsula is Seine Bight Village.  Over 700 Garifuna people make up the heart and drum beat of this fishing village where the dug out canoe is still the way to the sea.
