Belmopan

The Lonely Planet travel guide describes Belmopan with this:

Travelers arriving in Belize's capital are faced with the most basic of all existential questions. What am I doing here? Thankfully the town provides a ready answer: changing buses.

There really isn't too much to see in Belmopan unless you have an interest in administrative capitals. If you do find yourself there for a day it can be interesting to make a few friends by having a lunch of fish and rice and Marie Sharp's hot sauce on the picnic tables near the government offices with Belizean officials on lunch break.
