Bring your passport, this is the most important thing to bring while traveling to a different country. If you were to forget it, you wouldn't be able to go! Belize borders an ocean so if you are planning to go swimming, pack a swimsuit! With all the cool tourists attractions, you might want to pack a camera to take some cool pictures. When you are packing clothes, make sure to pack very summery clothes becasue of the warm climate. Sunglasses are also imortant. For bringing money to Belize, bring less than you need becuse they use Belizean dollars in Belize, which are worth more than U.S. dollars.
