Just wanted to pass on a suggestion for a place to anchor for awhile in Mexico while you go across to Belize to find a spot you like. We like the city of Chetumal. Kind of a large town with a small town feel. Good services, quiet, and friendly. This RV park is on the Mexico side but you are looking at Belize in the Background. Hope this helps. These pictures are from 3 years ago. Whew, time flys.
Here is there website link. It is called
Yax-ha ResortBoat launch.
Pool area.
A few cottages if you have friends visit.
There is a restaurant and bar right on site.
Good luck and happy trails.
