By ship
Several cruise lines call on Belize City. Unfortunately they usually stay only one day, which doesn't allow the opportunity to really see Belize. You can visit one of the Maya ruins, ride an airboat in the salt marshes just outside the city, shop, go to the museum, go to the zoo or take either a short cave rafting trip or go snorkeling, but that's about it. That means about 70% of the things most tourists would like aren't available, not mention the eco-tourism points of interest.
