Though many of the spots where travelers go are within walking distance of each other, it’s always safest to take a taxi after dark.
Belize City has the heaviest traffic in the country, as intense as that of a medium-sized country town in North America or Europe. There’s a limited one-way system, which is easy to work with. If you need to park on the street, try to do so right outside the place you’re staying. Never leave anything valuable on view inside a parked car.
Cabs cost around BZ$7 for rides within the city, give or take; if it’s a long trip from one side of town to the other, expect to be charged a bit more. Confirm the price in advance with your driver. Most restaurants and hotels will call a cab for you.
