LOOKING FOR A FERRY FROM CHETUMAL OR XCALEK TO NORTHERN AMBERGRIS CAYE...
Cross the border to Corozal, and take Thunderbolt: //www.ambergriscaye.com/thunderbolt/
They don't run to Belize City and Caye Caulker anymore, but still do the Corzal - San Pedro run.
Barbnov11,
there's no ferry service that I know of. However, the //www.ambergriscaye.com/thunderbolt/ water taxi will get you to San Pedro from Corozal. Alternately, you can fly on
Tropic Air or
Maya Airways for about US$40.
