When I got to the Belize City airport and heard that the cabbies wanted $17.50 US for a cab into town, I headed out to the highway and got a bus for $1.25. Oddly, when the trip was over, my ride back only cost 75 cents US.
It's only a half hour walk from the airport to the highway and that is like earning $35 per hour tax-free. Plus, I like to walk and I travel light, and the people who flew in with me were still milling around the carousel in hopes that the monsters they call suitcases show up. I sure didn't want to hang around to see if any of those people would like to share a cab.
It's a great way to save some money and see Belize from the beginning.
