Orange Walk is in northern Belize and most people use it as a jumping off point to the Mayan ruins of Lamanai.  This is a fun day trip as you get to the ruins via a 2 hour boat ride in which you a great chance of seeing crocodiles, various birds and various lizards.  The ruins are impressive and there is quite a bit of wild life there.  Orange walk is a good place just to hang out for a day or two.  Like most other cities in Belize, most of the restaurants serve Chinese food.
