Travel Ambergris Caye across channel to Mexico

Just curious. The channel  that divides the north end of AC and Mexico,  is there a way  to travel that? If so what  would  I find there? I heard  a lot of pdople go to Mexico  for health care  and dental  and  prescription drugs.

No, take the ferry from San Pedro to chet

Is Chet in Mexico? I am assuming so. Is that where you can get medical etc?

Chetumal is in Mexico you go to Cancun for medical

Merida Mexico is a popular destination for Medical checkups and surgeries.

Someone that lives there should discuss the passport stamp requirements and the fees to go between countries. We use to do it a lot but not lately; so I don't know the current fees or regulations.
