Passage over the road happens at Santa Elena, Belize into Chetumal, Mexico.
If you've got something to hide....Rio Hondo is the choice.

With Mexico to the north, Belize has become a stopover for smugglers traveling by land from Latin America to the United States.

Residents of Douglas in Belize know their village is a popular spot to smuggle goods and people into Mexico. The village lies next to the Rio Hondo River, which divides the two countries.

Belize has a surprisingly large Chinese population, making up more than 3 percent of the country's total population of 300,000. Those familiar with the trade say the smugglers are local Chinese-Belizean businesspeople.

Two men with bikes and a gaggle of kids show up when they realize someone is at the banks of the Rio Hondo. The river's edge is lined with trees and sugarcane. The water is still. Tied to the embankment are little canoes that locals say are used to shuttle contraband between Belize and Mexico.

The sun sets, and the light quickly slips into darkness. One of the men, in a white T-shirt and jeans, initially doesn't seem surprised by the visitor. But after some questioning, he becomes suspicious and says the canoes are used for fishing.
